Key Takeaways
- Pressure seal valves have evolved over roughly eight decades, with modern designs manufactured from materials like low carbon steel, chrome/moly, and austenitic stainless steel to handle increasingly demanding pressure-temperature requirements.
- Everlasting Valve Company’s process valves can serve directly as pressure seal valves, featuring a self-lapping, rotating disc design with an open body that is self-cleaning and produces a tighter seal the more it is used.
- Everlasting process valves are engineered to handle a wide range of extreme conditions — from full vacuum to 10,000 psi and temperatures from -50°F to 1,500°F — making them suitable for the most demanding industrial environments.
- Unlike ball valves, Everlasting process valves are specifically built to outperform when handling challenging media such as slurry, heat, chemicals, scale, and dry solids.
- Everlasting Valve Company takes a consultative approach with each client, assessing plant-specific challenges and customizing valve solutions to reduce downtime, lower maintenance costs, and improve overall operational efficiency.
At Everlasting Valve Company, we are different. It’s not just because we offer the most powerful, longest-lasting valves on the market today. It is in the way we do business with our clients. We become your partner in solving all of your valve problems from day one and we stay with it until you have what you want.
For anyone looking for high-pressure valves for heavy-duty applications, we are your go-to source. From chemical plants, refineries, power generation, to pulp and paper manufacturers, we can show you how process valves can be used as pressure seal valves.
For about eighty years now, pressure seal valves have been pushing the pressure-temperature envelope. Requirements were always increasing and designs needed to be kept up to date. Over the decades, pressure seal valves have been redesigned until today where they are manufactured from low carbon steel, chrome/moly, and austenitic stainless steel in pressure classes up to 4500.
Process Valves Can Be Used as Pressure Seal Valves
At Everlasting Valve Company, we take pride in all the valves we produce. From boiler blowdown and diverter valves to bulk material and process valves, our valves are built to last. You can literally pull one of our process valves off the shelf and apply it where it needs to go, but we can also customize our process valves to meet your exact requirements.
Our Process Valves are tough and built to last. Their platform is the original self-lapping, rotating-disc-valve design. It features an open-body concept that is self-cleaning with seats that wear in, not out. This is what gives it a tighter seal. And the harder it works, the better its performance.
Whatever operational requirements you need at your facility, we can customize those for you. We are always working hard for our clients and we look forward to our next big challenge. Innovation sets us apart and you will see it in our process valves, which you can use as pressure seal valves.

What Can Our Process Valves Do
Built for all industrial uses, our Process Valves have been proving themselves for decades in extreme environments where their performance is always on the line. Our Process Valves significantly outperform ball valves when it comes to handling slurry, heat, chemicals, scale and dry solids and they do so with noteworthy ease.
We know you have some of the dirtiest, grungiest applications there are. Our Process Valves will take them on and then some. Process valves, like pressure seal valves, have to take on the most brutal applications like business as usual. For every type of job, from pneumatic conveying systems, vessel discharge, lockhoppers, reactor loading to slurry applications in all types of extraordinary environments, there is nothing our process valves can’t handle.
Our valves reduce costs and downtime, and offer a tight shut-off, making them perfect as pressure seal valves. Our industrial valves will be the best valves you ever invest in.
Here is What We Do For You
Once you contact us, we quickly assess your unique plant problems. With your help, we begin to brainstorm solutions. We look to see what you need – boost efficiencies, reduce downtime, drive your maintenance costs way down – anything which has been negatively affecting your company. We then take those worn-out valves and replace them with the best you will ever encounter. We will build you the perfect valve and deliver it quickly, which means more money in your pocket when everything is up and running smoothly.
We understand the complications and challenges you face every day on the job. That is why, from the moment you contact us, we make it our priority to learn all about your unique plant environment and your goals. We can offer reduced maintenance costs, less downtime, increased productivity, and more.
At Everlasting Valve Company, our valves are engineered for exceptional performance. They last forever, which makes their value second-to-none. In addition to our process valves, we offer you bulk-material valves, boiler blowdown valves, and diverter valves. They are perfect replacements for metal seated ball valves, pinch valves, knife gate valves and globe valves, which other industrial valve manufacturers may offer you.
Don’t settle for second best. At Everlasting Valve Company, our commitment is to your company with our state-of-the-art valves.
Frequently Asked Questions
Pressure seal valves are widely used in chemical plants, refineries, power generation facilities, and pulp and paper manufacturing — anywhere that high-pressure, high-temperature fluid control is critical to safe and efficient operations.
Yes — Everlasting process valves are built on a self-lapping, rotating disc platform with an open body design, making them fully capable of functioning as pressure seal valves right off the shelf or customized to fit specific plant requirements.
Everlasting process valves significantly outperform ball valves when handling slurry, heat, chemicals, scale, and dry solids because their rotating disc design self-cleans and tightens with use, whereas ball valves are prone to wear and leakage under those same conditions.
Everlasting process valves can be configured with a range of end connections (flanged, buttweld, lugged, RTJ), operators (air cylinder, hand-wheel, electric, hydraulic), and accessories including solenoids, limit switches, and positioners to match any facility’s unique operational needs.
From the first point of contact, Everlasting works directly with clients to assess their specific plant problems, engineer a tailored valve solution, and deliver it quickly — with the goal of reducing maintenance costs, minimizing downtime, and improving long-term productivity.
