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 DN10 to DN50. 
They 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 VMP series air operated pinch valves can also be offered with alternative individually customised connections.

The general description of air operated pinch valves covers the operation and the benefits of air pinch valves.

Structure of VMP series

The structure of the VMP series air operated pinch valves encompasses the sleeve, a body and two end covers.
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 end covers, thus forming a compact unit.

Materials of AKO air operated Pinch Valves VMP series

A selection of 12 different elastomer grades for the sleeve (NR, NR food quality rubber, NR high temperature, CR, EPDM, EPDM food quality, FPM / FKM, Q, NBR, NBR food quality, IIR and CSM) 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 (FDA certified) 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).

For the nominal diameters DN10-15 stainless steel socket end covers are also availabel, see VMC series.
