Function of Air operated pinch valve
The air operated pinch 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.
Advantage of Air operated pinch 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, fibres, slivers, any kind of slurries and many more aggressive products. Usually conventional valves such as ball valves, butterfly valves, piston valves or gate valves tend to fail when in process with the above mentioned aggressive products. This reason is because the valve body seat or the gate/piston of the valves wears out too quickly and the valve can no longer shut off tightly. Whereas air operated pinch valve work without almost any wear of the elastic rubber hose because the kinetic energy of the solids are absorbed through the extremely high elasticity of the rubber. The rubber mixture is also anti abrasive
Air operated pinch valve Maintenance:
Quick and simple replacement of all sleeve types with the assistance of detailed fitting instructions for the air operated pinch valve is reflected in the very low maintenance costs Air operated pinch valves are used in a variety of pneumatic conveying systems, such as the silos/cement sector, pigment and granulate handling, the ceramics/glass/plastics industries, waste water treatment, pharmaceuticals and foodstuffs industry, and winemaking. In addition, air operated pinch valve is used in metering and weighing systems, powder coating systems, vacuum toilet systems, vacuum conveying systems and vacuum and compressed air control units.
