AKO’s pneumatic (air operated) Pinch Valves with weld-on end connections are available in sizes from DN10 to DN150, and comply with DIN EN 10357 Series A, or alternatively ASTM A554.
Pinch Valves by AKO with weld-on ends are compact and reliable units, consisting of only a rubber sleeve, body, and two weld-on end connections. The sleeve is clamped down into place by the weld-on ends. The limited parts required to form the Pinch Valve gives it an excellent total cost of ownership. No replacement seals, gaskets, rings, bolts etc are needed. The only wearable part is the rubber sleeve, which in many applications has a very long working life. This means you can install the Pinch Valve and leave it to do it’s job without fuss.
