VM Pinch Valves The body of the VM Pinch Valve is manufactured in aluminium alloy. The sleeves are made from fabric-reinforced material. The sleeve support bushes are made from either aluminium alloy, hardened carbon steel, or 304/316 stainless steel.Function: VM-type Pinch Valves are used for interception of the 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 that the passage is hermetically sealed. VM Pinch Valves equally handle pneumatically conveyed powders, granules, fibres, dense mixtures and liquids. |
