If you are considering purchasing a rubber pinch valve, consider its features and benefits. These include flexible elastomer, natural rubber, and simple design. You may also want to consider the sleeve material. These parts of a pinch valve make contact with the media, so you need to find one that has good abrasion resistance.

Natural rubber

A natural rubber pinch valve is used in applications where the material being manipulated is aggressive. It is particularly suitable for pharmaceutical, food, and chemical processes. Its rubber membranes are resistant to abrasion, and it can be used for high-temperature applications. In addition, it can be easily replaced on-site, which reduces production costs and downtime.

Pinch valves are available in a wide variety of materials. They can be made of synthetic rubber, chlorosulfonated polyethylene (CSM), butyl acrylate, silicone resin, and natural rubber. The main advantage of natural rubber is that it has high abrasion resistance, high rebound resilience, and high tear strength. This ensures the longest possible life for your valve. Natural rubber pinch valves are also very low maintenance.

Flexible elastomer

The Flexible elastomer pinch valve has two basic functions. The first is to pump fluid into the valve body, while the second function is to collapse the flexible lower part 36 of the sleeve. Using either option, the valve works the same way. Fluid is pumped into the valve body, and the sleeve collapses inward when the valve is compressed.

The sleeve and body are made of a variety of materials, including neoprene, natural rubber, silicone, and EPDM. EPDM is a synthetic rubber membrane that is extremely durable. It is also heat resistant, unlike natural rubber. FKM is another type of elastomer, which is more heat resistant than nitrile. Other materials used in the https://evrproducts.com/products/pinch-valves/ body of the Flexible elastomer pinch valve are stainless steel and aluminum.

Liner motion

A rubber pinch valve works by preventing a flow of fluid through a tube by limiting the amount of material in the pipe. It can be used in corrosive and abrasive fluid applications. These valves also require little maintenance and don’t need special actuators. They also require no packing, bearings or seals, making them ideal for these types of applications.

This valve functions similarly to a diaphragm valve, except that the closure member closes the valve to block flow. They also have a low pressure drop and are a good choice for liquids and slurries containing solids. They come in a single port and double port configurations.

Simple design

A rubber pinch valve is a simple device with three basic components: a flexible sleeve, a clamp, and an end connection. The sleeve is the only component that comes in contact with the media, while the end connection is used to connect the valve to the pipe system.

The body of the valve must be lightweight. The material of the sleeve should be chemical and abrasion-resistant. If any part of the material is damaged, it can interrupt the flow. This can lead to a buildup of memory and turbulence. It can also cause damage to the liner wall.


An economical rubber pinch valve is a versatile and reliable piece of industrial equipment for regulating fluid flow. Its unique design allows it to work efficiently even under tough conditions. Its high-performance, low maintenance cost, and long life make it ideal for industrial applications such as chemical processes, glass and cement production, and other processes that involve abrasive and highly corrosive media.

The heart of an economical rubber pinch valve is the rubber sleeve, which is reusable and can be replaced as needed. It has excellent wear and corrosion resistance, and good bearing pressure. There are several types of sleeve materials, depending on the flow media and operating temperature. An EPDM rubber pinch valve, for example, is designed to operate in high-temperature environments. It is important to ensure that the polymer used is suitable for the application. The pinch valve sleeve can be powered by electric, pneumatic, or hydraulic actuators.
