Product Summary

Air operated butterfly valve is a type of power operated valve that uses air pressure against a piston or diaphragm to produce linear or circular movement to operate a valve. The most important benefits of using air operated Pinch Valves are their complete and true full bore, and the 100% tight shut off – even on solids such as granules, powders, pellets, chippings, fibers, slivers, any kind of slurries and many more aggressive products.

Air operated butterfly valve are very easily constructed. They generally only consist of an extremely elasticized reinforced rubber hose, a type of housing, and two socket end covers or flanges. The rubber hoses of the air operated Pinch Valves are usually press-fitted and centered into the housing ends by the socket end covers or flanges. The air operated butterfly valve works without any additional actuator; all it needs to close or operate is 30 psi air supply into the Pinch Valve body. As soon as the air supply becomes interrupted and the volume of air exhausts, the elastic rubber hose starts to open due to its great impact resilience.

Air operated butterfly valve works the same way as other standard butterfly valves. The round disc is centrally mounted on a shaft, or stem, that runs through the center of it as the axis around which the disc rotates. When the valve is open, the disc lays parallel to the direction of the air flow; the disc is not thick enough to greatly inhibit the current yet is strong enough to shut tightly when the control lever or wheel is moved to the closed position. These seals do not perform well in high pressure applications and are therefore used mostly with lower pressures. Pneumatic butterfly valves are able to complete the seal when working at high operating speeds as long as the pressure is not also high.
