Supplying compressed air/fluid (minimum pressure difference 2 bar) into the casing of the  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 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 air operated Pinch Valves.

This specific, lipped fold pattern ensures the complete sealing of the product flow. Even large solids are enclosed by the sleeve in the air operated Pinch Valves and are thus tightly sealed.

Features and benefits:

minimum frictional resistance

100% leak free

no blockages and lightweight
