Product Description:

The body of the VM Pinch Valve is manufactured from aluminium alloy while the sleeves come in fabric-reinforced material. The sleeve support bushes are either made from aluminium alloy, hardened carbon steel, or 304/316 stainless steel.


VM-type Pinch Valves are used for interception of material flow in pneumatic conveying systems, or other pipelines. In addition, they can be installed as a locking device for silo filling pipes.
In the open position the internal cross section of the valve is identical with the connecting pipe diameter. By introducing compressed air or, especially with small valves, water under pressure through the threaded bore into the interior of the valve, the internal flexible sleeve is reshaped in such a way as to hermetically seal the passage. With VM Pinch Valves pneumatically conveyed powders, granules, fibres, dense mixtures and liquids can be equally handled.



  • Passage diameter from 13 mm (1/2”) to 200 mm (8”)

  • Working Temperature: -10 ~ 80 °C (14 ~ 176 °F)

  • Different sleeve materials suitable for material handled

  • Different bush materials suitable for material handled



  • Compact overall dimensions

  • Easy, quick sleeve and bush replacement

  • Full bore-through passage without any pressure loss

  • No material contact with the body

  • Suitable for explosion proof plants

  • Lightweight in comparison with other makes and other types of valve

  • Particularly low air consumption
