Pinch valves are a fully ported or full bore control valve that uses a pinching effect to restrict flow of fluid. These valves are used in a wide range of industries to control the flow of liquids and gasses. Read on for some common applications. There are a variety of pinch valve types, so it’s important to understand your options.

Flow control solutions

Pinch valves are popular in a number of industrial applications where shut-off and flow control are crucial. They are often associated with bulk materials handling, concrete production, and pneumatic conveying. They are highly efficient and are known for their high quality and reliability. A pinch valve is an excellent choice for many industries, including those with harsh media and corrosive environments. A pinch valve is a very simple, inexpensive way to regulate the flow of any material.

The basic design of a pinch valve consists of a mechanism inside the valve casing that is controlled by an actuator. This mechanism includes one or two pinch bars guided by two rods. Different actuators are available, including electropneumatic or digital models.

Common applications

A pinch valve is a type of valve that evr valve is used in a variety of applications. These include the dispensing of pharmaceuticals and medical devices, the treatment of waste water, and the handling of solids. These valves have low maintenance costs and are ideal for chemical and corrosive media.

A pinch valve is made of a rubber sleeve. This sleeve closes drop-tight around solids to prevent their entrapment. As a result, pinch valves are considered safer than other types of valves due to their 100%-tight shutoff.


A pinch valve is designed to close by exerting pressure greater than the operating pressure. The valve may not close if the pressure differential is too small. When choosing a pinch valve, its material should be able to withstand the expected application temperatures. Pinch valves are typically low-wear and have an efficient flow pattern.

This valve type has a wide range of applications. For example, it can be used to control the flow of abrasive or fibrous materials. Moreover, it has excellent resistance to water, alkalis, steam, and gases. It can also be used in systems that involve sand entrained water and sewage. Pinch valves are particularly good for pneumatic applications because they do not come in contact with the transport medium. They are also suitable for applications requiring high flow rates or for controlling the flow of liquids.

Selection criteria

Pinch valves are widely used in pharmaceutical, medical, and sanitary applications. They are easy to clean, and come in a variety of designs. Most pinch valves are designed to obtain high compression pressure, which allows them to drain thoroughly. Some types are straight through, which sustain a high flow rate with minimal turbulence. They also require little air consumption, which reduces the risk of airborne contaminants.

The material used in pinch valves is another critical factor. External pinch valves are most commonly made of a single wetted material, while internal pinch valves typically use multiple wetted materials. Choosing the material for an external pinch valve will depend on the flow capacity required, as well as the compatibility of the material used in the tubing.


A pinch valve is a solenoid valve used to control the flow of gases and liquids. The design of these valves eliminates dead volumes and the pressure of fluids is only affected by the area of the valve where the fluid touches. These valves are available from various manufacturers, such as Linquip.

Pinch valves are ideal for controlling the flow of a wide variety of products. They are composed of two half-bodies, with the external part made of aluminum and the internal part made of steel.
