Company profile

AKO Armaturen & Separationstechnik GmbH is a German company founded in 1984 with production in Germany and France. The company is now working with 30 national representatives and is able to offer its service all over the world. Longterm, efficient customer relations are among AKO’s success factors.

AKO is a manufacturer of pinch valves and has successfully placed their products in the market for three decades.

The principle of the pinch valve is simple: Supplying compressed air into the casing of the air operated Pinch Valve compresses the sleeve. The body’s design guarantees that the pinch valve 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 pneumatic pinch valve and completely seals off the flow of the product. As soon as the supply of compressed air is interrupted and the Valve casing is vented or drained, the specially manufactured sleeve is opened by its rebound resilience, enabling the pressure in the medium to flow through the full passage of the Pinch Valves.

With the help of detailed assembly instructions and new assembly videos, the pinch valve sleeve can easily be replaced by the customer on www.pinch-valve.com. Short production downtime remains therefore guaranteed.
