How to Choose the Right Rubber Pinch Valve

If you’re looking for a pinch valve that can handle a variety of bulk materials, you’ve come to the right place. Read on to learn about the resiliency of the material, the different applications, and the cost. Then choose the best one for your project. You’ll be happy you did.

Resilient properties

The resiliency of rubber pinch valves allows them to function well in a variety of applications. They are cost-effective, reliable, and easy to use. They can handle a variety of media, including slurries, granular materials, and oil. Pinch valves have a rubber sleeve that absorbs impact, deflecting it back into the media. These properties make them ideal for many industrial settings. In addition, pinch valves with a rubber sleeve have a longer service life than those with metal surfaces. However, they are not suitable for applications requiring high temperatures, since they can crack under pressure.

The rubber sleeve in PREMAFLEX pinch valve housings is highly elastic. When closed, it locks the product flow completely. This makes it possible for the valve to operate efficiently even under high switching frequencies. In addition, the rubber boot can open on its own once the control medium is removed. The resiliency of rubber pinch valves ensure that they can be operated at very low costs with minimal maintenance.


If you need a pinch valve to control the flow of abrasive or corrosive fluids, you need to consider theĀ try this site cost of a heavy-duty rubber pinch valve. These valves are designed to handle high-solids content media and offer high performance and low wear. They are ideal for proportional control applications in the mineral processing, cement, iron and steel, metallurgical and foundries industries, and aluminium production.

There are several types of pinch valves available. These include manual and pneumatic. They come with an internal liner made of a special material. The body of a pneumatic pinch valve is made of steel or aluminium, while the sleeve is made of a polyoxymethylene (POM) or natural rubber. Both types of material offer high strength, toughness, and elasticity.


Pinch valves are a versatile valve designed for slurries and granular materials. They are inexpensive, easy to install, and reliable. They utilize elastic tubing to form a seal equivalent to the permeability of the flow media. This enables them to handle a variety of fluids, including corrosive substances.

Because the rubber sleeve has a high elasticity, it absorbs the impact of flowing media without causing contamination or damage to other parts of the valve. The rubber sleeve also wears less quickly than metal surfaces, resulting in a longer service life.

Material selection

The material selection for a rubber pinch valve should depend on the application. When choosing a pinch valve, consider the type of corrosive fluid it will be exposed to. If it is highly corrosive, a material that is resistant to corrosion is ideal. The other important consideration is the material’s resistance to on-off cycling. A double wall design, for example, offers more protection than a single wall. It also has a simpler design, and it is suitable for highly abrasive applications.

A rubber pinch valve can be made of a wide variety of materials. For example, natural rubber, butyl, EPDM, and nitrile are suitable for various applications. Plastics and aluminum are also available as pinch valve materials.

Manufacturing processes

The manufacturing processes for rubber pinch valves are vital to the quality and reliability of the valve. These valves are used for a range of applications, from handling granular or slurried products, to controlling the flow rate of emulsions, dusts, and other media. They are inexpensive, reliable, and easy to use. In addition, these valves can be used with various materials and can improve the flow performance of laboratory equipment.

Rubber pinch valves are made of a rubber membrane that is highly elastic. The membrane closes and opens in the same elliptical shape after compression, ensuring a long service life. The membranes are usually made of top quality rubber that is resistant to abrasive materials. They also have a similar shape, making them a versatile, reliable option for industrial applications.
