1/2 inch Aluminum Pneumatic Pinch Valve With Rubber Sleeve – Abrasion Resistant

This is a G 1/2 inch aluminum pneumatic pinch valve with an abrasion resistant natural rubber sleeve for shut-off control applications with abrasive, corrosive or fibrous media. The valve can withstand a maximum operating pressure of 6 bar (87 psi). The control pressure (air) is max 2 bar (29 psi) higher than the pressure of the medium.

The valve is pneumatically operated through the air supply connection in the housing. This connection has a G 1/8 inch female thread. The pressurized air compresses the sleeve and provides a shut-off function of the valve. When closed, the sleeve forms a tight seal that will not allow the media leakage.

This valve is suitable for the operating temperature range from -10 to 80°C (14 to 176°F). This pneumatic pinch valve ensures an optimal shut-off, even when used with solids, such as granules, powders, pellets, chipping, sand, cement, gravel, textile fibers, carbon, fine glass fragments and slurries (liquids that contain solids).

Pros:

• Free flow of the media with minimal friction resistance
• Clog-proof
• Simple design not prone to malfunctioning
• No dead space for the media to get stuck into
• Suitable for abrasive media thanks to the abrasion resistant sleeve

Cons:

• Not suitable for vacuum applications since it could close the sleeve prematurely

PVLAL-P series

The aluminum pneumatic pinch valve from the PVLAL-P series are designed for shut-off control applications with abrasive, corrosive and fibrous media. The series includes pinch valves with female threaded ports (BSPP – British Standard Pipe Parallel), sizes ranging from 3/8 to 4 inch. The maximum operating pressure is at 6 bar (87 psi) and the maximum control pressure is 2 bar (29 psi) higher than the media pressure. These valves can be equipped with either natural rubber food safe sleeve, natural rubber abrasion resistant sleeve or EPDM sleeve. These valves ensure an optimal shut-off, even when used with solids, such as granules, powders, pellets, chipping, sand, cement, gravel, textile fibers, carbon, fine glass fragments and slurries (liquids that contain solids).
