How do air operated pinch valves work?

 

Supplying compressed air/fluid (minimum pressure difference 2 bar) into the casing of the TEKO air operated Pinch Valve compresses the sleeve, which is specially manufactured with high rebound elasticity. The body's design guarantees that the sleeve can close freely to form a lip shape. This ensures that the product flow is completely sealed off tight and that the sleeve is guaranteed the longest service life at the same time. This closes the air operated Pinch Valve and completely seals off the flow of the product.

The maximum operating pressure is dependent on the nominal diameter and is around 2-6 bar. As soon as the supply of compressed air/fluid is interrupted, and the air operated Pinch Valve casing is vented or drained, the specially manufactured sleeve is opened by its rebound elasticity/resilience, enabling the pressure in the medium to flow through the full passage of the TEKO air operated Pinch Valves.
