Flange Connection

AKO’s pneumatic (air operated) Pinch Valves with flange connection are available in sizes from DN25 to DN450, and comply with DIN EN 1092 (PN10/16) or ANSI B 16.5-150lbs as standard.

Flanged Pinch Valves by AKO are compact and reliable units, consisting of only a rubber sleeve, body, and two flange ends. The sleeve is clamped down into place by the flanges. The limited parts required to form the flanged 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.
