Interception of material flow in pneumatic conveying systems, and locking of silo-filling pipes.
The body of the VM/VMM 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 and VMM-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.
Regarding VM only, by introducing compressed air 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.
Regarding VMM only, by introducing compressed air into the two single action air cylinders, the internal flexible sleeve is kept open. In case of no presence of air, the cylinders will reshape the sleeve in such a way that the passage is hermetically sealed. VMM Pinch Valves can equally handle pneumatically conveyed powders, granules, fibres, dense mixtures or liquids.
