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

The air operated pinch valves of the VMP series are available in the nominal diameters of DN010 to DN50.

They are designed with an internal thread connection conforming with DIN ISO 228 and alternatively NPT as standard. On request, the VMP series air operated pinch valves can also be offered with alternative individually customised connections.

Structure of VMP series:

The structure of the VMP series air operated pinch valves encompasses the sleeve - the essential part of every pinch valve - a body and two collar caps. The pinch valve body is compiled of a main body part and two pressure zone rings, which are each pushed onto the ends and pressure sealed tight to the main body part using an O-ring. The pinch valve sleeve is positioned in the centre of the VMP series air operated pinch valve's body; both of its ends are pressed in by the collar caps, thus forming a compact unit.

Function of AKO Pinch Valve VMP series:

The VMP series air operated pinch valve is closed by differential pressure of 2-3 bar being fed via the medium/operating pressure (depending on the elastomer grade) into the pinch valve body. As soon as the pressure supply is interrupted and the pinch valve body bled, the pinch valve sleeve opens again completely because of its enormous rebound resilience.

Only the sleeve and the two collar caps are positioned in the product flow (contact with the operating medium) of the VMP series air operated pinch valve.

Materials of AKO air operated Pinch Valves VMP series:

A selection of 12 different elastomer grades for the sleeve (natural rubber, food quality rubber, high temperature rubber, neoprene, EPDM, EPDM food quality, viton, silicone, nitrile, nitrile food quality, butyl and Hypalon) ensures that the VMP series air operated pinch valves have a very wide and practically unrestricted field of application.

Furthermore, a selection of three different bodies and collar materials supports the diverse application of the VMP series air operated pinch valves. The following standard materials are available:

POM natural (white), for foodstuffs and interior applications
POM black, with additives to stabilise the effects of UV and weathering, therefore suitable for use in outdoor areas
POM conductive, suitable for using the VMP series pneumatic pinch valve in areas at risk of explosions (EX).
