Pinch valve
A pinch valve is a full bore or fully ported type of control valve which uses a pinching effect to obstruct fluid flow. There are a few types of pinch valves based upon application. == Fluids == Pinch valves used for fluids usually employ a device that directly contacts process tubing. Forcing the tubing together will create a seal that is equivalent to the tubing's permeability.〔(Quik-Stop Pinch Valves )〕 Pinch valves are typically used in applications where the media needs to be completely isolated from any internal valve parts or entrapments. They are commonly applied to medical instruments, clinical or chemical analyzers, and a wide range of laboratory equipment. 〔(Valcor Pinch Valves )〕
