Air operated Pinch Valve
The solution for isolating and regulating/metering abrasive, corrosive and fibrous products such as granulates, powder, pellets, dust and liquids containing solids, etc.
How do air operated pinch valves work?
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.
What are the benefits of air operated pinch valves?
• 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.
