Pinch valve - Wikipedia

A pinch valve is a full bore or fully ported type of control valve which uses a pinching effect to obstruct fluid flow. Operating principle. Pinch valves employ an elastic tubing (sleeve/hose) and a device that directly contacts the tubing (body). Forcing the tubing together will create a seal that is equivalent to the tubing's permeability. Air-operated pinch valves consist of an elasticised ...

Pinch Valve - How They Work | Tameson

A pinch valve consists of three major components: a housing, an internal rubber sleeve (orange section in Figure 2) and end connections. The rubber sleeve is fitted into the housing from inlet to outlet and is the only component that comes in contact with the media. The end connections are bolted, screwed or threaded at each end to provide support and connection to the valve. The valve is open ...

Pinch valves generally have a maximum operating temperature of 250 o F. At 250 o F, maximum operating pressure varies generally from 100 psig for a 1-inch diameter valve and decreases to 15 psig for a 12-inch diameter valve. Special pinch valves are available for temperature ranges of -100 o F to 550 o F and operating pressures of 300 psig. Most pinch valves are supplied with the sleeve (valve ...

Pinch Valve - Valvias

The sealing in pinch valves is achieved throttling the flexible tube of the valve named elastic sleeve which is the only part in contact with the medium. Pinch valves are suitable for handling slurries and solids in suspension, avoiding contact with the valve mechanism and any contamination towards or from the environment. Generally, the pinch valve is limited to work at low pressures. Pinch ...
