AKO air operated Pinch Valves with Internal Thread Connection - VM Series

The pneumatic pinch valves of the VM series are available in the nominal diameters of DN10 to DN50.

The AKO VM valves are designed with an internal thread connection conforming with DIN ISO 228 (G) and alternatively ANSI/ASME B1.20.1 (NPT) as standard. On request, the VM series pneumatic pinch valves can also be offered with alternative individually customised connections.

Pinch Valve Structure of Type VM

The structure of the VM series air operated pinch valves encompasses sleeve, pinch valve body, two sockets and two retaining rings. The pinch valve sleeve is positioned in the centre of the VM series air pinch valve's body; both of its ends are pressed in by the sockets, which are screwed to the body over the two retaining rings, thus forming a compact unit.
