Pinch valves are a simple design that has a wide variety of applications. They are often used in the chemical, wastewater treatment, and power plant industries. They are also used to control the flow of slurries and powders. These valves are available in both manual and pneumatic designs. They are easy to use and maintenance free.
Pinch valves are made up of two major parts: the body and the sleeve. The sleeve is the only part of the valve that comes in contact with the media. The sleeve is manufactured from a number of different materials, including NBR (nitrile) or natural rubber. The material of the sleeve is important to ensure that the valve will last for a long time. The sleeve should be made of a material that will tolerate application temperatures.
The body of the pinch valve is typically a flexible elastomer. The elastomer provides the flexibility to allow the fluid to pass through. It is important to find a material that is lightweight and will not damage the pipe. The elastomer must also be able to withstand the temperature of the application.
The sleeve is typically the only part of the pinch valve that comes in contact with the media. This part is manufactured from a number of different materials, such as natural rubber or silicone. The sleeve should be able to withstand the temperature of application and should be abrasion resistant. The sleeve should be designed to prevent leaks. The sleeve can be fixed to the valve with lug clamping screws. The sleeve can be changed on site if needed.
The sleeve of the pinch valve is the key to the valve’s quality. The sleeve is a wear-resistant anti-corrosion layer that provides the valve with a service life. The sleeve can be made of a number of different materials, including silicon, natural rubber, and nitrile. The sleeve is typically the single replaceable part of the pinch valve.
The pinch valve’s body can be made of a number of different material, including cast iron, aluminum, stainless steel, and food grade rubber. Depending on the application, the sleeve can be manufactured from a range of different materials, including nitrile, butyl, and silicone.
Flowrox offers a range of pinch valves that are suitable for heavy-duty applications. Pneumatic pinch valves can be actuated by air pressure, electric actuators, or hydraulic pressure. A pinch valve’s design provides excellent flow control while minimizing line vibration and noise. This rubber pinch valve type of valve is ideal for corrosive or abrasive media.
The pinch valve is commonly used in the sewage treatment, paper, chemical, and pulp mill industries. They are used to control the flow of slurries, powders, and granular goods. They are also used to control the flow in systems that require explosion-proof line closure. The pinch valve’s low weight and low maintenance make it easy to operate.
Pinch valves are a versatile and reliable design. They can handle a variety of materials, including sand, cement, and fibrous goods. They are often used to control the flow of gaseous or compressed air.
