Air or liquid pressure at the control inlet collapses the internal rubber sleeve to provide immediate and positive shut off. The rubber sleeve closes completely even on large particles, abrasive and corrosive materials. When open it allows full, unobstructed flow with little turbulence. The sleeves can be easily replaced when they wear out. To fully close the sleeve the valve requires a signal pressure 1.3 BAR (20 psi) greater than the media pressure. Great for chemical dosing, slurry, abrasive and dry materials. For other sleeve materials please contact us.


TECHNICAL SPECS

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.

Pinch Valves

Function

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.


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.


Features

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

Passage diameter: 40 mm (1 ½”) – 50 mm (2”) – 65 mm (2 ½”) – 80 mm (3”) – 100 mm (4”) – 125 mm (5”) – 150 mm (6”) – 200 mm (8”) (for VMM)

Working Temperature: -20 ~ 80 °C (-4 ~ 176 °F)

Different sleeve materials suitable for material handled

Different bush materials suitable for material handled
