A pinch valve is a device used to isolate a flow media from its environment. It consists of a sleeve made of rubber with a flexible elastic surface. These devices are used for a variety of laboratory equipment and medical devices. Generally, these devices isolate a flow media from its surroundings to reduce contamination.
Rubber pinch valves are used to control the flow of fluids and gases. They are characterized by a rubber tube with steel bars along the centerline. The rubber sleeve will stretch and close as the flow media increases. As it closes, the material build-up will flake off. As the sleeve stretches, the pressure from the click here for more info nipple travels down the internal part of the valve. This action causes the valve to close.
Pinch valves can be manually or mechanically operated. The mechanical mechanism can be either pneumatic or hydraulic. It is also possible to use an air injected into the valve body to close the valve.
Rubber sleeve
Pinch valves contain a flexible elastomer sleeve that contains a cast metal housing. The sleeve is pressurized by air or water to close the valve. When the pressure is removed, the valve opens normally. However, if a sleeve fails, controlled material may enter the actuation system. To avoid this situation, it is important to follow the proper maintenance procedures.
Pinch valve sleeve production processes vary depending on their complexity and application. Some of them include manual winding and conventional injection processes. Other methods involve manual packaging in moulds. The sleeve’s construction determines its cycle frequency, opening and closing characteristics, and is also important for ensuring a long service life. Different elastomers are used for different applications and operating temperatures. The quality of the elastomer also dictates the lifetime of the valve and its resistance to abrasion.
Besides high-quality synthetic sleeve materials, a good pinch valve sleeve is also made from natural rubber. This type of rubber is known to have excellent tear strength, high rebound resilience, and is resistant to abrasions. A sleeve made of natural rubber is a great choice for many industrial applications.
Rubber sleeve liner
A pinch valve sleeve is the outer layer of a valve that is designed to contain a flow of fluid. It is made of rubber or synthetic material and includes a pinching mechanism. The rest of the valve’s operating parts are external to the valve and are not in contact with the fluid. Its molded structure is reinforced with fabric and has smooth walls that minimize line vibration and turbulence. The valve is designed to close and open quickly and securely. Its streamlined flow pattern also reduces wear on the sleeve.
The sleeves can be designed according to your particular pinch valve needs. If you are unsure about the exact specifications for your valve, just ask the company’s experts. They will recommend the most appropriate rubber type for your application. Common types of rubber include abrasion resistant NR, nitrile, gum, and Butyl rubbers. The company also provides an ordering guide to help you determine which size is right for your application.
