A pinch valve is a simple device that provides effective flow control. These valves are often used in industries where the pressure of the media is high. For example, they are commonly used in the cement industry. They also are used in the food processing and pharmaceutical industries. They are also widely used in the paper and electronics industries.

A pinch valve is made up of three main components. They include the rubber sleeve, the housing, and the end connections. The sleeve is the only part of the pinch valve that comes in contact with the media. Therefore, it is important that the material is durable and resistant to abrasion.

The material of the sleeve is largely dependent on the type of media that is being controlled. Some common types of sleeves are natural rubber, EPDM rubber, and butyl rubber. Each has their own characteristics and benefits. If the sleeve is made from natural rubber, it is highly durable and has good rebound resilience. However, it is possible to use other sleeve materials depending on the fluids that the pinch valve will be operating in.

EPDM rubber pinch valves have flexible sleeves that are resistant to abrasion. They are easy to replace and provide low maintenance costs. The material is also suitable for regulating the fluid flow in a number of applications. This is especially true for applications where the temperature of the media is higher. It is available in a variety of sizes and designs.

Heavy duty pinch valves are great for abrasive fluids and corrosive media. They can be used in metallurgical, foundry, and mineral processing applications. The service life of these valves is quite long. They are particularly ideal for the aluminum and steel manufacturing industry.

The inner bushing of the pinch valve is often made of elastomer, such as silicon resin or fluoro rubber. It is important that the material is able to withstand the rigors of the application. It is also critical that the pinch valve’s control pressure is not more than 3.5 BAR. If the line pressure is too high, it may collapse theĀ pinch valve pinch valve. In addition, the pressure differentials must be calculated carefully. If a pinch valve is opened with a pressure difference of more than 5 BAR, the sleeve is likely to deform. In order to prolong the life of the sleeve, the control pressure must be reduced.

Pinch valves are an inexpensive and efficient way to regulate the flow of media. However, if you use the wrong kind of sleeve, the valve may not open or close properly. It is usually a simple problem that can be addressed quickly and easily. The key is to select the right pinch valve for your specific needs. A pinch valve should be able to handle the media’s pressure, temperature, and abrasion resistance. It should also be able to open and close at full bore.

If you are looking for a high-quality pinch valve, you should consider a pinch valve from the Flex-Valve(r) line. They offer abrasion-resistant, non-clogging, and corrosion-resistant pinch valves.
