Pinch Valves VM-VMM

• 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.

• 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

Benefits:

• 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 (VM only)
• Lightweight in comparison with other makes and other types of valve
• Particularly low air consumption (VM only)
• Food-grade contact parts.
