Function of Air operated Pinch Valve:

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

Advantages of air operated Pinch Valves:

Air operated Pinch Valve

Free flow of product, minimum frictional resistance, 100% leak free, no blockages and low net weight are among the most important benefits of air operated Pinch Valves.

A flattened and elliptical casing design of all flanged types ensures minimum compressed air consumption. This results in energy savings and ensures a specified, lipped fold pattern to the sleeve of the air operated Pinch Valve.

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. 

Air operated Pinch Valve Versions:

A wide variety of materials for the casing, flanges, sockets and sleeve qualities reveal a very wide field of application for the air operated Pinch Valves.

Maintenance of an Air operated Pinch Valve:

Quick and simple replacement of all sleeve types of the air operated Pinch Valves with the assistance of detailed fitting instructions for them is reflected in the very low maintenance costs.

Industrial Sectors Air operated Pinch Valve:

They are mainly 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 Valves are used in metering and weighing systems, powder coating systems, vacuum toilet systems, vacuum conveying systems and vacuum and compressed air control units.
