AKO air operated Pinch Valves with Flange Connection - VMC Series
The air operated pinch valves of the VMC series are available in the nominal diameters of DN025 to DN080.
They are designed with a flange connection complying with DIN EN 1092 (PN10/16) as standard
On request the VMC series air operated pinch valves can also be provided in compliance with DIN 11853-2 and DIN 11864-2 Form B.
Structure of VMC series:
The structure of the VMC series air operated pinch valves encompasses the sleeve, a body and two flanges.
The pinch valve sleeve is positioned in the centre of the VMC series air operated pinch valve's body; both of its ends are pressed in by the flanges, thus forming a compact unit.
Function of AKO Pinch Valve VMC series:
The VMC 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 flanges are in the product flow (contact with the operating medium) of the VMC series AKO air operated pinch valve.
Materials of AKO air operated Pinch Valves VMC 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 VMC series air operated pinch valves have a very wide and practically unrestricted field of application.
The body is available as follows:
- Powder-coated aluminium body
- Electro-polished stainless steel body.
The standard material for the flange is stainless steel 1.4404 electro-polished; other types of stainless steel are available on request.
