For any heavy industrial application, but especially in petroleum refineries and other processing industries, there is always a need for reliable and durable valves. This applies particularly to valves that have to operate under the extreme conditions of heavy industrial applications that involve high pressure, high heat and constant use.

The high-temperature flow control valves at the Everlasting Valve Company are no strangers to heavy industry. They’re designed specifically to operate exceptionally well over extremely long periods of time under tremendously stressful, diverse conditions. These conditions can include high heat, enormous pressure and varied processing materials. It doesn’t matter to these valves.

Everlasting Valve Company also produces top shelf, high-endurance versions of two key types of high-temperature valves. These are process valves and diverter valves. Let’s have a closer look at both.

The Mechanics of High-temperature Process and Diverter Valves.

For high-temperature flow control valves, The design used by Everlasting Valve Company is based on literal decades of field-tested and highly rugged technology that’s used in extreme environments. These valves are designed to outperform ball valves for a wide range of handling needs. They can robustly manage the flow of slurries, chemicals, highly heated liquids and also dry, abrasive solids. These valves are regularly used to manage applications such as loading reactors, pneumatic conveyance, vessel discharge, moving slurries, petroleum refining and materials processing. They’re basically built for the harshest environments and industrial uses you’re likely to encounter.

Both valve types are assembled with a self-lapping, rotating disk valve design that’s designed to self-clean and wear in such a way that performance actually improves over time. As the rotating internal disc inside these valves slides across the valve body while the system is operational, it cleans the precisely lapped surface of the valve interior while also clearing away lingering materials that’s being piped through.

Everlasting’s diverter valves work in much the same way except that they offer dual branching internal valve entrances that are both serviced by an alternating rotating disc much like the one found in a process valve. Because the internal disc can be switched back and forth as needed on the fly, production and material flow can be maintained uninterrupted as you pump material to multiple receptacles without the need for downstream line plugging.

Because the design of Everlasting Valve Company’s high-temperature diverter valves is open-body, they’re exceptionally good at letting even highly abrasive materials with particulate matter flow freely without clogging over time. The self lapping disc inside them rotates to polish away scratches as they form, and thus creates a seal that in fact improves over time.

It’s also seriously worth noting that both the company’s process and diverter valve discs are kept in constant, firm contact with the piping seat inside the valve with heavy-duty coiled springs in the disc center. This unique technology lets these valves also adjust themselves vertically in a way that negates the possible plugging and seizing effects of thermal expansion. For valves that process materials at both extremely high and sometimes low temperatures, this design feature becomes crucial.

Essential High-temperature Valve Specs

Everlasting Valve Company’s process and diverter valves are both perfectly capable of handling temperatures of up to 1500°F (815°C). In the case of process valves, pressure tolerances sit at ANSI Class 50 through 2500 with full vacuum tolerance of up to 10,000 psi. These valves can handle abrasives, corrosives, slurries, high-temperature liquids and coking materials among others. They’re also high cycling and bi-directional.

The company’s diverter valves offer pressure tolerances of ANSI Class 150 and 300 with vacuum tolerance of up to 100 psig. Both types of high-temperature valves come in a range of different sizes that for diverter valves range from 4” (100mm) through to 14” (350mm) and include 5” (125mm) sizes. For process high-temperature valves, sizes range from ½” (12mm) to 18” (450mm).

Why Use Everlasting Valve Company’s Unique Valves?

The features, tremendous strengths and benefits of Everlasting Valve Company’s high-temperature valves are numerous. If you need valve technology that just doesn’t quit suddenly with high repair-downtime costs as a result, these are the valves you need for even the most high-stress industrial materials handling needs.

How To Prevent Unplanned Outages

Downtime — it costs tons of money and reduces productivity, whether it is planned or unplanned. That being said, planned downtime for scheduled maintenance is quick and controlled, whereas unplanned outages can cause even more of a headache and stress. When unplanned outages strike, they can:

  • Really kill your profits
  • Cause production to grind to a screeching halt
  • Rack up repair costs
  • Necessitate wage payments without any work actually being done
  • Waste materials
  • Waste manpower
  • Cause missed deadlines and delays
  • Frustrate your own clients and damage trust and working relations
  • Lead to loss of business
  • Require a lot of work and expenses to start back up

In short, nobody enjoys the chaos of an unplanned outage. Thankfully, the risk of unplanned outages can be minimized by making a few mechanical or procedural changes and planning ahead. Some changes can also reduce the total periods of inactivity when outages do occur.

Common Causes of Outages – And Their Fixes

Knowing the common causes of unplanned outages means that you can efficiently prepare for the right fixes, which will either speed up your start-up or reduce the amount of downtime in general. In essence, expecting the unexpected can really help to manage sticky situations and kickstart operations as soon as possible.

Equipment Malfunctions

Number one on the list is equipment failures, or breakdowns. When there are so many parts involved with a manufacturing or other industrial process, one part that fails is enough to bring everything to an abrupt stop. Machines may stop working because of clogs and jams, wear and tear and similar. Parts wear out with age and use, with some consumable parts needing replacement more than others and some parts of equipment more prone to damage than others.

Equipment may also fail because of misuse and human damage, whether deliberate or accidental. Human error (detailed more below) can be a huge contributing factor to mechanical malfunctions.

Many people involved in repairs know that valves are a common issue leading to breakdowns. Some may choose to replace these valves more frequently as a solution, but while it does reduce the risk of outage, that tactic costs a lot of money in the long run.

Equipment malfunctions can be reduced by choosing quality equipment and parts in the first instance. For example, look for items that have longer guarantee periods and a good performance track record. Maintaining and cleaning equipment in the recommended way, at the recommended time and using recommended products can also help to prevent unforeseen equipment failure. For example, parts that need regular oiling should be oiled on schedule.

Workers should be adequately trained on how to operate machinery to prevent breakages and damages. Furthermore, staff members should only be allowed to operate machinery after a senior staff member is confident that they fully understand relevant processes and procedures.

Cleaning and Maintenance

Cleaning and maintenance are also problematic at times, when a machine part needs to be cleaned or maintained as soon as possible and cannot wait for a scheduled outage. When these actions aren’t performed well (as they may be in the rush of an unplanned outage) the problem compounds. Cleaning and maintenance needs may have been miscalculated, delayed or prompted by some other unforeseen event, such as misuse, a spillage, or similar.

Scheduling routine cleaning and maintenance works during quieter periods of operation can go a long way towards reducing unplanned outages. You can better manage your operations when outages are expected than when they are not. This goes for meeting production deadlines, having fewer staff on-site, minimizing wasted power, time and costs and managing client expectations.

Staffing Issues

Unplanned outages may also occur due to staffing issues. If you do not have an operator, you cannot run your operations, which means downtime is imminent. This kind of outage can often be prevented with careful staffing choices, and a contingency plan for if and when someone is sick or otherwise unable to come to work. You may consider, for example, cross-training staff members so as to be proficient in operating various pieces of equipment to allow for easier cover, and implementing a stand-by roster to ensure someone can always be available at short notice.

Changeovers between staff, and personal breaks that are not arranged wisely can also cause short outages, if things are not moving quickly and seamlessly. Find ways to make processes more efficient. Operator errors, too, can jam the system. Again, this is a staffing issue that needs to be addressed with careful planning, training, and processes in place.

Outside Factors

External factors can create issues with outages; these largely cannot be controlled. For example, power outages, water shortages, fires and natural disasters, such as floods, hurricanes and storms, will most certainly create problems for plants.

While you may be able to put some contingency plans in place, such as having a power backup, this is the kind of outage that is hard to plan for. In these cases, it is largely about mitigating losses and getting up and running as quickly as possible as opposed to preventative measures.

Non-Compliance

Many industries are governed by strict rules and regulations. Production facilities may be inspected at any time to ensure compliance. If a facility is found to be non-compliant, they may need to pause operations until such time they are re-assessed and found to be in compliance. As an aside, non-compliance can also lead to costly fines and other punitive measures.

The simple way to avoid possible unplanned outages in this case is to make sure all of your operations are compliant with relevant rules.

Other ways to reduce unplanned outages can include:

  • Ensuring safe working conditions
  • Having tighter monitoring systems in place
  • Identifying common causes of outages and finding solutions
  • Shift from a reactive mindset to a proactive one

How Everlasting Valves Can Help to Minimize Unplanned Outages

We cannot train your staff for you, nor can we assure that you will never face a power supply shortage, but we can help with a lot of the common causes of unplanned outages, well in advance so that your business is taking a proactive approach.

Given that equipment failures and breakdowns are a leading cause of outages, it simply makes sense to invest in parts that are designed to last. Sure, you can keep spending money on replacement valves, but that adds to your overall costs and does not help with outages, as you have to shut down parts of your facility to install the replacements.

With Everlasting Valves, you can get ahead of the equipment failures and rest assured that you will not be dealing with the ongoing expenses and frustrations of replacement valves. That is because our unique valves are truly designed for durability over the long term, as the toughest, longest lasting, best performing valve available.

The unique self-lapping, rotating disk action of Everlasting Valves ensures that, as your machines rely on these valves, the valves actually improve over time, polishing themselves and getting a tighter and stronger seal as time goes on. Our valves don’t wear out, they wear in. That solves the number one issue with unplanned outages, which may in fact give you more time and energy to hone in on other causes of outages.

The self-cleaning nature of Everlasting Valves also solves the problem of downtime owing to maintenance and cleaning. Yes, you still have to properly clean and maintain the rest of your equipment, but you can cross valves off your list, which makes the outage shorter.

You can rely on Everlasting Valves to supply your business with all of the valves you need, whether it is one of our stock options, or a custom-built valve for your business alone. We build all of our valves from design through to manufacturing, so you can count on us to provide your company with what you need, even if other manufacturers say it cannot be done.

We’re here to help you cut down on outages — both planned and unplanned — with the years of experience and carefully developed skills and industry knowledge that keep our clients happy. Connect with us today to learn more about how Everlasting Valves can help your business thrive.

For any heavy industrial application, but especially in petroleum refineries and other processing industries, there is always a need for reliable and durable high temp valves. Any valve used for throttling and on/off control must be made of materials to withstand constant high temperatures. High temperatures are usually any process fluid greater than 400° F / 204° C. Most refinery applications are less than 1,500° F / 816° C.

In refinery applications, many processes require the separation of crude oil into marketable oils and distillates. High-temperature valves in such applications are a given with processes demanding even higher temperatures. Ball valves are usually involved in these typical petroleum applications. They don’t always prove to be durable or reliable, though.

When ball valves break, they often do so without warning. This can put your company’s processes into a stall mode where downtime takes away from precious refining applications. If you have had this happen to you repeatedly and need to find a better way, contact Everlasting Valve Co.

High Temp Valves

Heavy-duty valves that operate in severe environments are key to maintaining your business operations. While most operations use ball valves, there are prone to break without warning. Most high temp valves are stainless steel and are highly durable. However, picking the right one is usually best done after in person analysis from an expert.

The valve industry is undergoing a huge surge in demand. The industrial valve industry may increase by 4.9% by 2025. This might not sound like a lot, but it equates to $103 billion. The reason for this growth is partly population growth, combined with heightened demand, and the fact many older models of valves are failing.

Choosing the Right Valves

Unlike ball valves, high temp valves are designed for severe environments. Routine maintenance can ensure that your valves don’t break without warning. Though all high temp valves are made from strong materials, you want to ensure that the ones you choose do not lose yield strength and are not prone to heat damage. Before you go ahead and purchase a high temp valve, ask yourself: what is the highest operating temperature this valve is going to have to manage?

Industrial Application

The best high temp valves offer support to a range of industrial applications. Most engineers use ball valves for high temp operations. We don’t.

Everlasting Valve Company’s original self-lapping rotating-disc valve is the highest quality valve you can use for your business. The largest benefit of these and our other high temp valves is the way they slide into your operations.

You’ll easily save time and money by reducing the amount of work maintaining one of our high temp-specific valves. For example, if you work in petroleum refining, you know how dirty and exhausting the work is to replace a broken ball valve. Wouldn’t you prefer to do smaller, routine maintenance that doesn’t cost your company huge sums of money? That’s why you need to avoid ball valves.

We Have the Best Alternatives to High-Temperature Metal Seated Ball Valves

At Everlasting, we have the valves you need for any severe environment usage. For all of your dirtiest, most brutal environments, Everlasting has the high temp valves you need. Our valves go where most don’t want to venture, such as:

  • Petroleum Production
  • Petroleum Refining
  • Power Generation
  • Chemicals
  • Petrochemicals
  • Cement Production

and more.

Over a century ago, Everlasting Valve Co. introduced their original self-lapping, rotating-disc valve to the world. It has become the gold standard for heavy-duty valves ever since. We’ve made our valves to clear out and shear away process material, achieving an even tighter seal with each pass. Our valves wear in overtime, not wear out.

If you are in the market for a better solution, take a look at our process valves and diverter valves. They are durable, reliable, and ideal for high-temperature applications, especially in places such as petroleum refining.

Process Valves

When you need to replace your high-temperature ball valves, consider our process valves. Everlasting’s process valves have many decades of proven service in the most extreme environments. They significantly outperform ball valves. They are adept at handling chemicals, slurry, dry solids, scale and high heat, and they do so with ease. Our process valves can take on the worst situations, where applications are the most brutal, hottest, and dirtiest. Where other ball valves fail, our process valves keep giving.

You’ll find process valves from Everlasting Valve all over the world where you see lock hoppers, pneumatic conveying systems, reactor loading, slurry applications, vessel discharge, and more. Because of their extraordinary reliability, process valves will reduce or eliminate downtime. That should be a real cost saver for you.

We build process valves using our innovative self-lapping, rotating-disc-valve platform. They feature a unique open body design that’s self-cleaning, with metal seats that wear in, so performance is exceptional and seals keep getting tighter. During operations, the rotating disc slides across the valve’s body, clearing out material that would otherwise build up and cause problems.

Best of all, if what we have on our shelves doesn’t work for you, we can customize our process valves to meet your precise requirements. Don’t replace ball valves more than once a year. Replace them once with the best process valve in the business.

Industrial Water Valves | Benefits Of Everlasting Valves

The industrial water valve can control the rate of flow into a device or system to avoid damage due to overpressure or other problems. They are typically found in systems where chemicals, gases, and other liquids are forced through an enclosed space...

The industrial water valve can control the rate of flow into a device or system to avoid damage due to overpressure or other problems. They are typically found in systems where chemicals, gases, and other liquids are forced through an enclosed space like pipelines. The valves are also used when various fluid levels must be met along the way to guarantee maximum efficiency in manufacturing processes.

Any industrial valve will consist of at least three essential parts; a spool, stem, and disc. The discs are generally referred to as the “seats” since they control the flow rate into the device. On the other hand, the stems are attached to the discs and allow operators to spin them into position for different types of flow rates depending on their needs.

By having these valves in place, companies can help ensure that there won’t be any issues with pressure or overloading, saving time and money for maintenance. Everlasting Valves, which are known for their durability, can be used to meet these needs. Traditional industrial water valves were only designed for small operations, but Everlasting has moved to upgrade even these kinds of valves with their heavy-duty seals and seats.

Here are the benefits of using these valves:

Reduced Overloading

If the fluid is forced through a pipeline, it creates an amount of pressure that can cause damage to the system if not managed. The valves allow operators to control the rate at which these fluids are allowed into the device so they aren’t overloaded beyond what it can handle.

This will prevent any malfunctions while allowing for the most efficient output process. Everlasting Valves can reduce the risk of these problems occurring. If the valves have a greater flow rate, the less likely it will be to overload.

Prevention of Product Contamination Due to Improper Fluid Levels

It’s essential to avoid any issues when fluid is being introduced into a device since it can cause problems within the system if not managed properly. These valves can help prevent the media from being contaminated due to overfilling or under-filling because of their ability to have different types of flow rates.

Everlasting offers a wide range of valves that can meet these needs depending on the manufactured product or fluid used in the system itself.

Reduced Product Damage from Overpressure

The flow rate into an industrial device can reduce the amount of damage caused by overpressure, which is a major reason why valves are used in the first place. When excessive pressure is introduced into a system, it can cause product damage and potential accidents for personnel who may be working with these systems at the time.

This type of industrial water valve will help ensure that operators can properly monitor the flow rate to avoid any issues with overpressure.

Smaller Down Time

Since Everlasting Valves are so durable, they don’t need replacements as often as traditional water valves tend to be. The reduced rates of replacement save time and money for companies and lower your downtime by improving productivity. This means that businesses can stick to their timetables without disruptions.

Higher Flow Rates

The Everlasting valves allow for maximum flow rates so that operators can use the system at its highest capacity. This will provide more efficiency since it won’t have to stop along the way, so fluid can be added or taken out, also slowing down the process. Since they can handle heavy-duty industrial applications, you can be confident that they’ll perform at high levels even under pressure.

Easier Maintenance

Fluids in systems like these can be very abrasive, which can cause extreme damage over time. Since valves allow operators to control the flow of fluids into different parts or devices within a system, it saves them from maintaining individual components of the mechanism. It also makes it easier to replace the valves if they are worn out or damaged without worrying about repairing or replacing long pipelines filled with chemical substances.

Putting a stop to damage due to overloading is simply the first step for improving productivity and efficiency. But, Everlasting has also made sure that these devices work even harder for you by allowing for shorter downtimes. They’re built to last longer while still providing higher rates of flow, so they save businesses time and money on maintenance while increasing the overall output of the system.

Increased Safety for Workers

The valves can also help increase the safety of workers in various ways. Without making any pressure adjustments, operators can keep systems from being overloaded with these devices while still allowing for the right levels so there aren’t any errors when using them.

Since they have more corrosion-resistant materials, Everlasting valves can help keep systems running smoothly for extended periods without necessarily being replaced.

Trying to control the flow of fluids through a pipeline is often done manually, which means there’s room for errors. With an industrial water valve in place, operators can control them whenever necessary, so there’s no chance of overloading. This will protect the system from damages that might occur if any malfunctions happen due to corrosion or other issues within the pipeline.

Customized Options

There are a few different Everlasting Valves to choose from depending on your needs and the type of system you’re using. They also come in various sizes, openings, and pressure requirements to be used for a wide range of applications. This makes it possible to ensure that each product is as useful as possible while still working within your budget.

By having these valves in place, companies can achieve maximum efficiency without taking the risks of uncontrolled processes. They are simple enough to install, require minimal maintenance, and last for many years before needing any repair or replacement. They are designed for heavy-duty industrial applications but can also be used in many other demanding environments.

Everlasting’s valves provide an easy way to control the flow of fluids through a system by letting you monitor its pressure and limitations. Their durable housing is built to handle corrosive substances without wearing out too quickly, meaning they’ll keep

“We appreciate the support from Everlasting and the quality products you manufacture.”
Marlon Marshall, President,
Matt Marshall Co.

For all steam-boiler operations, you want the most effective valves you can find. It almost seems impossible to find that valve to clear away sludge and other impurities that build up in harsh applications. When you want the best replacement for valves, look no further than Everlasting Valve Co. for all of your steam valves.

Our original boiler blowdown valve was first manufactured over 100 years ago for the harshest of industrial applications. Since control is required for many applications involving industrial steam valves, these valves become a vital part of the process. Steam valves can be gate valves, ball valves, butterfly valves, angle valves, and more.

Traditional valves may work perfectly up to a point then cause failures you didn’t see coming. Certain of these types of valves are not suitable for sustained throttling applications. Suspended particles can settle and become trapped in body cavities in slurry applications, potentially leading to leakage or valve failure.

Other types of steam valves are unsuitable for high pressures or need ambient temperature compensation. Occasionally, thicker sludge may stop the movement of the disc, causing downtime that offsets any cost savings you may have initially enjoyed.

How Everlasting Boiler Blowdown Valves Make All The Difference

Don’t keep replacing your ball valves or gate valves with the same type of valve. They wear out quickly, especially in industrial steam applications. We’ve designed our steam valves to create an effective seal for far longer than traditional valves.

At Everlasting, our boiler blowdown valves avoid these traps. Our valves leverage our exclusive self-lapping, rotating-disc-valve technology. This technology was originally designed with boiler blowdown valves in mind but has spread, over the decades, to every type of valve we offer at Everlasting Valve Co.

Our boiler blowdown valves have the exceptional ability to handle sludge, high temperatures, and intense pressures produced by any boiler. This means our valves last significantly longer than others and do not always need to be changed during scheduled maintenance. This dramatically reduces your costs and production times. Using our rotating-disc-valve technology, these valves simultaneously clear out harmful particles while cleaning the precision-lapped surface.

Thanks to Everlasting Valve’s boiler blowdown valve, you won’t have to replace a valve every time your boiler is taken out of service. Plus, our boiler blowdown valves come in a variety of configurations to suit your needs:

  • quick-opening
  • slow-opening
  • straight pattern
  • angled pattern
  • WYE pattern

At Everlasting, we offer boiler blowdown valves and diverter valves, process valves, and bulk material valves. They will replace valves you have in your plant operations, they will last longer and prove more reliable than any valve, even steam valves, you have used previously.

Process Valves

Everlasting Valve Company’s process valves are a superior replacement for faulty ball valves because of their ability to handle the toughest applications. Our process valves were engineered with one thing in mind: bearing the most brutal, hot, and dirty industrial environments imaginable. Try them for yourself, and they’ll rise to the challenge every time.

Like all of Everlasting Valve’s products, our process valves use our original self-lapping, rotating-disc-valve technology. However, our process valves also implement a unique open body design that is self-cleaning. Also, these valves are designed with seats that wear in, not out, for a seal that gets harder as it works.

While tons of our customers buy our process valves straight from the shelf, Everlasting Valve Company can customize our product to meet your exact specifications if needed. With a plethora of end connections such as flanged, buttweld, or lugged, our process valves are fit for practically any job.

Bulk Material Valves

Everlasting’s patented bulk material valve is the longest-lasting and best performing valve of its kind on the market. Barely breaking a sweat, this valve can handle the most abrasive, high-cycling, high-temperature applications.

In addition to our original technology used in all our valves, the bulk material valve uses an open-body configuration that allows particles and debris to move freely for easy cleaning and expelling when the valve opens. Using its unique shearing action that clears the sealing surface, the valve forms an even tighter seal over time. In fact, high-cycling applications will make this valve stronger with each repetition.

Not only is this valve built to get stronger in the toughest applications, but it can be used in a wide range of severe plant environments as well:

  • dry solid plants
  • dense and dilute-phase pneumatic conveying systems
  • in transfer lines
  • silos
  • cyclones

That’s just a taste; our bulk material valve can be used for even more. If you want to make everyone’s life easier, boost efficiency, and reduce maintenance costs, this is the valve for you.

Diverter Valves

We’re proud to say that our diverter valve has been installed in some of the most unrelenting plant environments all over the world and continues to function decades later. These valves were designed by our engineers to withstand the most intense and abrasive media your plant can give.

Using the same technology as our other valves, this diverter valve lasts years longer than traditional diverter valves. Better yet, these valves can be switched on the fly to ensure uninterrupted production. Best used for applications with extensive erosive slurry or abrasive solids, this valve has plenty of room for media to flow freely and expel easily. Not only will you be impressed with this valve’s efficiency, but you’ll be impressed with your plant’s efficiency as it can continue to function between planned shutdowns.

Versatile and Certified Steam Valves

Our self-lapping, rotating-disc technology was introduced in 1906 and has been the gold standard for severe-service valves ever since. Each time the disc rotates, the action it produces renews and polishes the metal seating surfaces. Each Everlasting valve wears in, not out, which makes for a tighter seal every go-round. When other valves fail, ours keep on giving.

A variety of plant environments all around the globe use our valves. You can find these valves in applications, such as:

  • Cement Production
  • Petroleum Production
  • Petroleum Refining
  • Petrochemicals
  • Chemicals
  • Power Generation
  • and more

We’ve designed all of our valves to meet the crucial standards of any severe-service environment. Our steam-boiler-blowdown valves, the first valves ever produced by Everlasting Valve Co., meet ASME / ANSI Boiler & Pressure Vessel Code for blow-off service. The valves can replace any gate valve, ball valve, globe valve, or pinch valve in various applications.

When it comes to harsh and abrasive environments, our valves have yet to meet a material they can’t handle. From hot-catalyst handling to fluid-catalytic cracking, our valves handle all manner of slurry, sludge, dry solid, abrasive, or other erosive material you can think up. They perform perfectly every time. Everlasting valves beat other valves, hands down.

Solenoid valves are widely used across various industries and applications. Finding a good solenoid valve manufacturer, then, is often the difference between a process that works, and one that fails. Cheap valves are inexpensive because they are low quality, ready to break or fall into disrepair at any time, which means your entire system goes offline while the problem is fixed.

A good solenoid valve manufacturer won’t create or sell you junk valves, but rather, cares about your company’s work and supports it through providing high-quality equipment.

Here’s why you need a good solenoid valve manufacturer, and how to find them.

What is a Solenoid Valve?

A solenoid valve is used to shut off, release, or otherwise control fluids. They offer the ability to control fluid automatically, vital to the operations of many plants and equipment types. A solenoid valve is either electrically energized or de-energized to control fluid flow, based on an electromagnet that opens or closes the valve.

There are various types of solenoid valves, whether direct-acting, internally piloted, or externally piloted. They also come in different designs based on the number of port connections or fluid flow paths available.

Solenoid valves are widely used because they’re so versatile. They work efficiently as a control valve, while reducing the reliance on manual operations. That being said, they can be finicky — solenoid valves don’t handle dirt, debris, or moisture very well, as that impedes the electromagnetic solenoid coil, which is what automates the valve. Valves, of course, need to open and close to do their jobs, and whether it’s a dirty valve, coil burn out, a partially closed valve, or another issue common to cheap valves, it can grind your plant to an expensive halt.

The Value of a Solenoid Valve

There are many solenoid valve applications and uses, often in pneumatic and hydraulic systems. An electromagnet opens or closes a valve, stopping or allowing the flow of fluid to parts of a machine.

While some solenoid valves only control the flow through a single path, other types of valves have connections to two, three, or even more directions. Solenoid valves are controlled directly or piloted internally or externally.

High-quality solenoid valves are a growing industry standard because they are so versatile. Solenoid valves reduce the need for manual fluid controls and are simple to operate. Though they are easy to use, they can also be damaged or worn out, especially if they come in contact with foreign material like dirt, debris, or outside moisture. A weak or non-functioning valve can mean you have too much fluid, or not enough when you need it.

The Signs of a High-Quality Solenoid Valve

High-quality solenoid valves need to withstand high temperatures and pressure from the fluids rushing over them. They have to be able to stand up to regular wear and tear without decaying or breaking apart. Poorly made solenoid valves can save you money at first, but when they burn out, refuse to close tightly, or get dirty, you’ll be looking for someone that can make them better.

That’s what you’re looking for from a solenoid valve manufacturer. A simple online search will show you many valve makers. You’re looking for one that emphasizes quality and manufacturing processes that work to avoid the decay and damage that affects low-grade valves.

Solenoid valves with an open body design are made to flow freely. They won’t get clogged with contaminants that can harm the valve and the lines connected to it. The open body design carries those contaminants away. They can’t build up around the valve, making it weaker and less secure.

Custom Design From Your Solenoid Valve Manufacturer

Solenoid valves have a wide variety of uses, and can even be an accessory added to other types of valves, like bulk material valves and process valves. But sometimes even that isn’t enough to make sure your factory can keep operating smoothly.

You might need a custom design option, like valves built especially for your unique machine or that can endure the rate of fluids moving through your system. Contact a manufacturer’s engineering team to help design an innovative solution for you.

Choosing the Right Solenoid Valve Manufacturer

Going the cheap route might seem compelling in the beginning, when you feel like you’ve gotten away with a steal of a deal, but that all falls apart when your valves do. Many of the disadvantages of solenoid valves can be overcome by finding the right solenoid valve manufacturer.

Like any other valve, a solenoid valve should be robust enough to withstand high temperatures, high pressure, challenging environments, and wear and tear over time. Anything less than that, and your company will be spending a lot of money repairing and replacing valves on a regular basis.

At Everlasting Valve Company, you can count on our valves to work hard for you, no matter the challenges of your environment. That’s because our valves start with you and your plant in mind. We work to understand the specific environment and goals of your company, and to deliver the valves that do the job, and do it right.

Why are our valves better than the rest? It’s simple. Each Everlasting valve wears in instead of out. The rotating disc polished and renews its seating as it’s used, so the seal gets tighter and better over time, instead of gradually falling into disrepair like other valves.

Our valves are self-cleaning, with an open body design. When you consider that many of the problems with solenoid valves stem from contamination, you can see why Everlasting Valve Company products are a better choice. Our valves move particulate and debris out of the system every time they are used, instead of allowing that damaging material to build up and clog the valve.

Using Everlasting Valve Company as Your Solenoid Valve Manufacturer

We pride ourselves on our ability to efficiently and effectively meet our clients’ needs for valves of all types, solenoid valves included. Both our bulk material valves and process valves come with the option of a solenoid accessory to automate your processes with the best valves around.

If you don’t see a product of ours that meets your needs, do not worry. Our engineering team is dedicated to finding innovative solutions for each and every one of our clients. Yes, it costs more to invest in an Everlasting Valve Company product, but we are called Everlasting for a reason — the cost of the valve will absolutely pay itself back over time as your equipment continues to not only function but also improve, versus having to shell out time and time again to replace and repair those cheap valves.

Oil and Gas Valve Manufacturers

We are at the brink of a new industrial age, but oil and gas are and will probably remain the defining fuel of our immediate future. Petrol and its derivatives are set to continue to dominate the market with plastics and other petrol-based products remaining at the forefront of our industrialized society.

At Everlasting Valves, we are old hands at working with oil. We understand the extreme pressures and exacting standards that oil-operating gear must tolerate. And you’ll be pleased to know that we have adapted our valves to suit them.

Over a century old and already a market leader as oil and gas valve manufacturers, our company cut its teeth on the toughest oil terrain there is: Alaska. In 1995, our valves were used in the first-ever Hydrocyclone on Alaska’s North Slope. The task at hand was the removal of seawater, sand and contaminants from crude oil in low-pressure wells. Our valves continue to be incorporated into the basic design of all hydrocyclones.

Our understanding of the extreme conditions that our oil and gas valves face has made us a master in our field. We not only engineer for what is there, but we imagine every possible contingency, from extreme weather conditions to extreme pressures and corrosive materials. Even the most corrosive materials will remain sealed regardless of high pressures. We make our valves to outperform all competitors and to perform above the industry’s standards.

Our patented and tested self-lapping, rotating disc valves are machine-lapped several times while in production. This process creates a valve with a seal that outperforms the industry standard. Even better, the internal mechanism of our valves polishes the interior of the valves while in use. This removes any corrosion and scratches that may weaken its sealing properties over time, creating an even better seal each and every time they’re used.

A cautious and conservative approach to engineering leads our designers to test and try each of our products while in production and also in the field. We don’t accept that our valves may fail on the job, so we put them through their paces and test them under grueling conditions.

The result is a robust, no-nonsense valve. Our heavy duty valves are all but indestructible and incredibly durable.

Putting aside our valves stellar performance in extreme weather conditions, you will find that there are many additional reasons to opt for Everlasting valves. Efficiency and cost-effectiveness are imperative for any oil or gas operation in which total control of flow is not desirable but a must.

We understand that valves need to work perfectly, at all times and for a very long time for a company to thrive. A leaky valve is not only dangerous for employees but also a ticking time bomb that may create an ecological disaster, as well as damage material and the company’s reputation.

This is something no company can easily step away from. This is why operating with the strongest most reliable valves on the market is not a matter of choice but one of necessity.

We won’t be boasting about how pretty our valves are. Our focus remains on your business needs, so we make our valves as functional, tough and resilient as possible. We make our valves to the highest standards and then some. We expect them to work perfectly and factor many elements that could affect their performance into their design.

The #1 Choice for Petroleum Industry Manufacturing Valves

Ever since we first introduced our original self-lapping, rotating disc valve in 1906, we have been the industry leader for oil and gas valves. Our Everlasting Valves are different from others in that they renew and polish the metal seating surface each time they move. They become more efficient as they work rather than wearing out and needing to be replaced. We have a variety of valves on the market today that can replace globe valves, ball valves, and gate valves for a variety of industrial applications.

Custom-Designed Solutions

Here at the Everlasting Valves Company, we can offer you custom-designed solutions that are unique to your industrial application needs. First, we’ll visit your industrial site, talk with you about your challenges and needs, and observe the conditions of your industrial environment. Then, using our original self-lapping, rotating disc valve as a basis, we will build in features to suit your requirements.

Oil and gas manufacturers trust Everlasting Valves for their performance, durability, and longevity. We design our valves to withstand the harshest industrial manufacturing environments. In fact, we have valves that have been in operation for 50 years!

Reduce Downtime and Increase Your Bottom Line

Due to the durability and nature of our Everlasting Valves, the days of stopping production to replace valves will be a thing of the past. And the fact that our valves become more efficient with use means your production efficiency will increase. Fewer downtimes reduce maintenance costs, and when combined with better production efficiency, the result is an increase in your overall bottom line.

Unbeatable Everlasting Process Valves

Our process valves have been designed to withstand the most extreme environments and hold up against heat, dry solids, chemicals, and slurry. Everlasting process valves are self-adjusting and can help reduce fugitive emissions. They can be installed right off the shelf or customized for your unique applications.

Valves That Can Handle Petroleum Refining

Petroleum refining is probably one of the hottest, dirtiest, and roughest processes there is. These conditions are no problem for our valves, though. Our valves outcompete the other refinery valves on the market by a long shot and can handle fluid catalytic cracker (FCC) units and continuous catalytic reformers (CCRs) with ease. If you are constantly replacing valves that leak and fail within a month, then it is time to invest in one of our valves.

Everlasting Valves Outperform and Are Worth Every Penny

An Everlasting valve is an extremely reliable valve that will stand the test of time and remain functional for much longer than its competitors. Our valves are made to function with any type of liquid and slurry, remaining tight. They are effective when it comes to controlling the flow at all times, reliably, day after day, year after year. This quality is, of course, very important when dealing with remote, hard-to-reach areas. And this is becoming an increasing necessity with gas and oil fields being exploited in more inaccessible and remote areas. Less maintenance, coupled with better performance and reliability, makes for less maintenance and better operational security.

Everlasting valves are the essential tools that will help keep your operation safe and cost-effective. A functioning valve can make the difference between industry success and a catastrophic accident.

As long time oil and gas valve manufacturers we offer a tested valve that has been in continuous use for several decades in some of the worst terrain and most exacting industrial conditions imaginable. What other competitors may claim to be able to do, we have done and have continued to do since the last century.

According to a recent EPA survey, more than 40,000 tons of fluids are emitted and lost from tankers due to leakage. If you are one of those who have experienced this issue in your organization, then you know that there is no easy way to fix it.  However, if you want to prevent valve leakage from happening again, you need to do something about it immediately. Well, in this article, we will be sharing some information about control valve leakage. Read through also to understand control valve requirements.

Control Valve Application

A control valve is used to regulate the flow of liquid. In other words, it helps to control the amount of liquid that flows through the pipe. It does this by opening and closing the pipes. When the pipes are open, then the liquid can flow freely. On the contrary, when the pipes are closed, then the liquid cannot flow. Leakage in a control valve occurs when the liquid leaks through the joints between the pipes.

Causes Of Control Valve Leakage

There are several causes of valve leakage. Some of these include:

Improper Installation

If you have installed your control valves improperly, then you might not realize it until you notice water leaking out of your faucets. You should never install your valves without first checking whether or not they’re properly secured.

Poor Maintenance

It’s also possible that your valves have been neglected over time. They could become worn out due to constant use. As such, you’ll need to replace them before they break down completely.

Faulty Parts

The parts of your system that are responsible for controlling the flow of water may fail to work as intended. For example, if you have an old-fashioned ballcock valve, then it’s likely that its internal components will eventually wear out. It’s best to get your valves replaced when they start malfunctioning.

Damaged Pipelines

Damaged pipelines can cause leaks in your entire system. To find out if this is the case, you should check all of your pipes for cracks and other damage.

Everlasting Valve

Our valves have been created to prevent leakage or evaporation of liquid from fluid storage tanks.

Specifications

This valve can handle pressure ranging from 10 psi to 200 psi. It is made using stainless steel material. The valve comes with a lifetime warranty.

 How Does The Everlasting Valve Work?

When you fill your tank with fluid, the Everlasting Valve automatically closes the opening of the tank. As soon as the fluid level reaches the top of the Everlasting Valve, it opens the tank’s opening. When the Everlasting Valve detects the presence of air inside the tank, it closes the opening again.

Why Should You Use Everlasting Valves?

There are many reasons why you should consider using Everlasting valves instead of other types of valves. Some of them include:

Prevents Tank Leaks

Most people experience liquid leaking from their tanks when they don’t use any kind of valve on their tanks. If you have ever experienced such a problem, then you know how frustrating it can be. If you are not using a valve on your tank, there is always a chance that the fluid could leak out through the tank’s cracks. Everlasting valves eliminate this issue because they keeps the tank sealed until the liquid level reaches its maximum capacity.

Reduces Corrosion

Another advantage of using Everlasting valves is that they reduce the chances of corrosion. Conventional valves usually allow water to flow into the soil around the tank. When the fluids gets contaminated with dirt and bacteria, it causes the formation of rust.

Extends The Life Of Your Storage Tanks

One of the most significant advantages of using Everlasting valves is that they extend the life of your storage tanks. As mentioned earlier, conventional valves often cause corrosion. This leads to the deterioration of the tank walls over time. However, installing our valves on your tank helps keep the tank walls intact for longer periods. These are just some of the benefits of installing Everlasting valves on the storage tanks.

Factors That Affect The Performance Everlasting Valves

To get the best performance from Everlasting valves, you need to ensure that all factors are taken care of. The factors include:

Make Sure That The Valve Is Installed Properly

You must ensure that the valve is appropriately installed. You need to make sure that the valve completely covers the tank so that no fluid leaks out. If you do not follow this step correctly, you will have the same problems that you were trying to avoid in the first place.

Check The Pressure Range

Before filling your tank with water, check the range of pressure that our valves can handle. This is done by placing the valve under a high-pressure hose.

Keep an Eye Out For Air Bubbles

Air bubbles can also affect the performance of valves. Make sure that you remove all the air bubbles before filling the tank.

Clean the Tank Regularly

Cleaning the tank regularly is another crucial factor. Make sure that you clean the tank at least once every month. You should also make sure that you use a good quality cleaner and regular valve maintenance.

Get an Everlasting Valve Today!

If you want to avoid control valve leakage, then you need to take some precautions. For example, you need to follow these steps:

  •         Make sure that your pipes are properly installed
  •         Keep an eye on the temperature of the water
  •         Check if the pipes are clogged

With Everlasting valves, you will never have to worry about having a problem with the control valve again. They are designed to last for decades. For more insights on Everlasting valves and control valve products, please contact us today.

Factory valves have infinite value when placed in oil rigs, chemical plants, and cement production plants because they provide so many different industrial applications. Often it is the best of industrial valves that can be modified or adapted through innovation. It is this innovative valve that replaces the ball, globe, gate, and pinch valves.

In fact, almost every type of factory or plant environment can benefit from having the right type of industrial valves. The question becomes, what is a factory valve and what’s the right type for my plant environment? A valve is defined by the category it’s in, and that’s specific to the valve’s operating mechanism.

When you’re able to use an industrial valve that makes your life easier because the valve helps your industry become more efficient, that’s a winning combination.

What Is a Valve?

There are a variety of valves with each one providing a different category for diverse operating environments. The below are just some of the more common types of valves. But because the list is somewhat extensive, there are some very innovative and adaptive valves not listed.

  1. Ball – is perfect for a quick turn-off valve because it can be turned off with just a 90-degree twist. Most valves need 360 degrees to turn off manually.
  2. Bulk – this is a valve that lets particulates move freely with its open body configuration. This allows for easy cleaning and expelling because the valve opens up.
  3. Butterfly – is a valve best known for the large-diameter pipes it controls with its unique on and off flow control.
  4. Check – valves that help piping systems avoid reverse flow, protecting their mechanical equipment from particulates or fluid.
  5. Choke – is a valve that is used for high-pressure drops that are usually found in oil and gas wellheads. The valve is inside or around a cylinder and lifts another cylinder up or down as needed.
  6. Diaphragm – is a valve also known as the membrane valve. It’s typically used in pharmaceutical environments because it can control the diaphragm flow by movements.
  7. Diverter – is a valve that is revolutionary by using rotating disc technology for self-lapping applications.
  8. Gate – is an excellent way to implement on and off control every time there is a low-pressure drop.
  9. Globe – a valve that uses a cylinder’s movement to regulate the flow over a seat.
  10. Knife – a valve that’s compact and uses slurries or powders that function as a gate valve does and operates with it’s on and off capabilities.
  11. Needle – a valve that is one of the best if you want accurate flow control.
  12. Pinch – this valve is used by many factories that need controlled regulations. It works with the slurry flow.
  13. Piston – this valve provides fluids that are regulated and move them into the suspension as a solid-state.
  14. Plug – is a valve that deals with pressure drop in factory environments that rely on its on and off control mechanisms.
  15. Solenoid – valves that are electrically actuated are used most of the time to provide pneumatic fluid control conditions.

Finally, there’s the spool valve that provides hydraulic control that is used in environments that need more choke valve applications.

What is Valve Seat Leakage?

Like any part of your machinery, the valve seat can undergo wear and tear over time, which affects its functionality. One of the most common valve seat problems is leakage (which can occur even when your valve is off). If left unaddressed, excessive valve seat leakage can interfere with production and can ultimately lead to unplanned downtime.

The ANSI FCI 70-2 offers six different classifications for valve seat leakage, which will tell you the following:

  • The maximum amount of leakage permitted
  • Medium used to test valve
  • Pressure used to test valve (in pounds per square, or psig)

Let’s take a more in-depth look at each of these classifications.

Class I (Dust Tight)

The first class is for metal or resilient seated valves. While it has the same design and construction as classes II, III and IV, it does not come with a maximum leakage amount or any testing procedures.

Class II

This class is designed for double port or balanced single port valves (generally with a metal piston ring seal and metal to metal seats).

  • Maximum leakage allowed: 0.5% of rated capacity
  • Test medium: Air or water at 50-125⁰ F
  • Test pressure: 45-60 psig

Class III

Like Class II, this class is made for double port or balanced singe port valves.

  • Maximum leakage allowed: 0.1% of rated capacity
  • Test medium: Air or water at 50-125⁰ F
  • Test pressure: 45-60 psig

Class IV (Metal to Metal)

Class IV is designed for single port and balanced single port valves that have extra tight piston seals and metal to-metal seats.

  • Maximum leakage allowed: 0.1% of rated capacity
  • Test medium: Air or water at 50-125⁰ F
  • Test pressure: 45-60 psig

Class V

Class V is intended for the same valves as Class IV. However, it differs in terms of maximum leakage amount, test medium and test pressure.

  • Maximum leakage allowed: 0.0005% of rated capacity
  • Test medium: Water at 50-125⁰ F
  • Test pressure: Maximum service pressure drop

Class VI (Soft Seat)

This class is reserved for soft seat valves, in which either the seat or shut-off disc (or both) are made of a resilient material, such as Teflon.

  • Maximum leakage allowed: 0.15 to 6.75 ml per minute (depending on valve seat size)
  • Test medium: Air or nitrogen at 50-125⁰ F
  • Test pressure: 50 psig

What Causes Valve Seat Leakage?

Valve seat leakage can be caused by several problems, such as:

  • Damage
  • Open valve
  • Improper sizing
  • Improper installation
  • Low quality

Over time, your valves may become damaged. Even a small amount of damage inflicted upon the seat or the valve seal can result in leakage. In other cases, the valve may simply not be closed. Anything from dirt to debris can prevent your valve from closing properly.

Alternatively, you might simply have an ill-fitting or low-quality valve. Some valves come with weak off/off capabilities that negatively affect their function, while others are simply not installed correctly.

How Can I Recognize Valve Seat Leakage?

If you’re not sure whether your valve seat is in top-notch condition, it might be a good idea to check. The test used to evaluate valve seats depends on the classification:

  • Classes II, III AND IV: Pressure is applied to the valve inlet while the outlet is open.
  • Class V: Pressure is applied to the valve inlet after the body cavity and connected piping is filled with water.
  • Class VI: The vehicle’s actuator is adjusted based on the operating conditions, while a closing thrust is applied to the valve plug seat.

Depending on the cause of the leakage, you might be able to resolve the problem quickly (for instance, if the valve seat is blocked, the issue can be solved by removing the obstruction). In more severe cases, you might need a replacement. When selecting a replacement, it’s important to go with a high-quality brand that can guarantee durability and longevity, such as Everlasting Valves.
