This video shows how an Air 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. works.
Supplying compressed air 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.
