AKO’s pneumatic (air operated) Pinch Valves with threaded spigot connections are available in sizes from DN10 to DN100, and comply with DIN 11851. The threaded spigot end connections can also be provided in 11853-1 on request.
Pinch Valves by AKO with threaded spigot ends are compact and reliable units, consisting of only a rubber sleeve, body, and two threaded spigot connections. The sleeve is clamped down into place by the threaded spigot 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.
