Pinch Valve

Pinch valve is a full bore or fully ported type of control valve, using a pinching effect to close or open a fluid/gas flow. It utilizes pressurized air to open or close the valve. In the open position, the valve has no restrictions and allows a wide range of media to pass through the bore. The flexible internal rubber sleeve in the valve keeps the media isolated from the rest of the valve, preventing contamination or damage to the valve’s other components. Pinch valves employ an elastic tubing (sleeve/hose) and a device that directly contacts the tubing (body). Forcing the tubing together creates a seal that is equivalent to the tubing's permeability.Pinch valves are typically used in applications where the flowing media needs to be completely isolated from any internal valve parts. The sleeve will contain the flow media and isolate it from the environment, hence reducing contamination. They are commonly applied to medical instruments, clinical or chemical analyzers, and a wide range of laboratory equipment. They are used in some water pistols, notably the original Super Soaker
