Mining Valves

Valves are used daily in the world of heavy industry and in the mining industry. Safety and production rely on these valves. Without them, the work would be less efficient. We make custom mining valves for our clients, but as a primer here is a sampling of valves used in the mining industry.

Check Valve

These are considered to be unlike other types of valves in that they allow fluids to pass in one direction only. This prevents any overflow and it’s also done for safety’s sake. Fluid and gas are drawn into the valve and are separated into two ports – water is pulled through the first port into the second port. Fluids flow out of an opening and return to the first port.

Types of Check Valves:

  • Ball Check Valve
  • Swing Check Valve
  • Disc Check Valve
  • Split Disc Check Valve
  • Diaphragm Check Valve
  • Wafer Check Valve

Ball Valve

The part of this valve that opens and closes is called the ball. This is where the ball valve gets its name. They are “wide-duty” valves, in that they have the ability to transfer various types of gasses, liquids, as well as liquids that have suspended solids.

Ball valves are known for their uniform sealing stress abilities and they are straight-through valves. They can be used in the mining industry, but, as they can not be cleaned easily, they would not be conducive to such industries as food or pharmaceuticals. For more info, see our article on high temperature ball valves.

Common ball valves include:

  • Valve stops
  • Swing check
  • Standard face-to-face dimensions
  • Position indicators
  • Fire-safe

Butterfly Valve

This type of valve is used to control flow through a system. Also known as a rotary motion valve, they are found in the mining industry due to several beneficial properties.

They have excellent control capabilities, and they have a tendency for less plugging. Due to how they can be customized, butterfly valves can be used in areas of small dimensions. They keep the flow moving in one direction and prevent back-up. They can be very difficult to clean, however, and should be limited to areas such as the mining industry where cleanup and cleanliness are not an issue.

Butterfly valves will either be concentric, double eccentric, or triple eccentric. And all butterfly valves will share these three features:

  • Equal percentage;
  • Linear;
  • Quick opening.

Knife Gate Valve

These valves were originally used in the paper and pulp industry. They were designed to cut through the pulp in the paper, specifically. Knife gate valves can cut through thick liquids. They quickly proved advantageous in the mining industry. Almost every industry now uses knife gate valves.

Knife gate valves are made of heavy metal cast iron which helps them to cut through grease, oils, wastewater, varnish, and any other sludge or slurry that flows through them.

The valves offer many useful features, including:

  • Cast iron body;
  • Heavy-duty top;
  • Replaceable wear seats;
  • Precision machines gates;
  • Solid stainless steel lining.

Control Valve

A control valve automatically regulates pressure and flow rate. They are used in plants, manufacturing, and in mining industries because of their ability to be a part of a larger control loop where networked valves all work together.

Control valves all work differently and can control various types of pressure in diverse industries, as well as manufacturing.

Characteristics of a control valve include:

  • Equal percentage;
  • Linear;
  • Quick opening;
  • Hyperbolic;
  • Square root.

The mining industry relies heavily on control valves. They are paramount to controlling pressure and flow. Without them, the industry would not function.

To sum up, mining valves are necessary to the industry today. They are incredibly useful in a variety of applications within the mining industry. Within the mining industry, mining valves are vital.

Pinch Valve

This mining valve’s purpose is to either restrict or completely stop a given material from flowing through. The pinch valve, like almost all other mining valves, has a multitude of designs. It has either an extremely elastic sleeve or an insert that can be put into the body of the valve. These mechanisms are what allow the pinch valve to close or restrict flowing material.

Air pressure or the use of mechanical help can be used to make the elastic sleeve or insert close or restrict flow through the valve. Pinch valves are ideal because they can be used for extremely long ranges

Globe Valve

Globe valves have a similar purpose as mining valves except they work to specifically control or halt the flow of either water or some type of gas. The seat of a globe valve is located dead center of the valve while at the same time being parallel to the pipe.

The opening of the seat can be closed off using two mechanisms. These are either a disk or a plug inserted within it. Additionally, the globe valve is given its form by the baffle. This baffle splits the pipe right in half. Due to this design, using the baffle is not ideal when working with thick substances. The reason is that the baffle will restrict the flow of these substances.

Gate Valve

The gate valve while also similar to the knife gate valve is unique in its respect. This mining valve is typically best used when you either want to completely stop the flow of a material or to let it completely flow through.

Because of this, the gate valve is not ideal if you want to control the flow of material passing through. Pressure should never be impacted by the gate valve whether it is left open or closed.

Diaphragm Valve

We know much about durable valves, and the diaphragm valve is just that.

The diaphragm valve is used in a multitude of industries besides just mining. Because of this, diaphragm valves can be made out of different materials depending on the purpose they will be used for. The diaphragm valve has a flexible membrane built into its design. This membrane is used to open and close an opening. The membrane can be opened or closed by manipulating the amount of pressure that comes at it. These mining valves can get their pressure from a variety of sources. Some valves utilize air pressure, while others use electricity.

There are two different types of diaphragm valves. The first is the weir diaphragm, which is also called the saddle type. This type of diaphragm valve is used on pipes that require to flow of gasses, fluids, and slurries through them.

The second type of diaphragm valve is called the straight-away and is also referred to as straight through. This type of valve is usually put at the bottom of tanks as a means to controlling the outflow from them.
