pinch valve, air operated pinch valve, valve sleeve, pneumatic actuator, pump, pipeline

The Fengchi Pneumatic Heavy Duty Pipe Clamp Valve is equipped with a double-acting straight-stroke cylinder. The minimum standard supply pressure for cylinders is 6 bar. Cylinder size is determined according to the process line pressure. Pneumatic actuators can also be used for special materials for demanding applications.

Technical parameters:
Diameter range:15~2000mm.
Pressure rating: 1~ 10Mpa, 1:2 safety factor of the burst pressure.
Body Material:
DN15~200 (carbon steel, ductile iron, aluminum alloy, stainless steel - casting process)
DN250~2000(45# steel, stainless steel welding process)
Material of the valve sleeve: natural rubber, EPDM rubber, neoprene rubber, nitrile rubber, butyl rubber, fluoroelastomer, Heparen
Fully open: The full-bore elastic sleeve of the pipe clamp valve is free of any gaps and dead angles.
In Closing: The midline is closed, a feature that avoids turbulence and wear within the casing, and the valve sleeve becomes a smooth, closed Venn's tube that cleans itself with each operation.
Shut-off: The pipe clamp valve ensures a two-way zero-leakage closure when fully closed, with an intrinsic safety design without seals that require maintenance.

Advantages and features:
The working principle of the wind chi pipe clamp valve is very simple. In the open position, the valve is fully open with no flow limit. During shutdown, two clamping rods press the valve sleeve against the centerline. The valve sleeve is wear-resistant, solid particles hit the rubber surface of the valve sleeve, the valve sleeve absorbs energy, and the valve sleeve rubber restores shape, releasing the energy. Even if there is solid debris accumulating on the valve sleeve wall, when squeezing the valve sleeve, any crystalline particles will fall off the surface of the valve sleeve and flow away with the medium, so that the heavy pipe clamp valve can achieve an airtight level seal. The valve's full-bore construction ensures the free flow of the medium. The structure and materials of the three main components of the valve (valve sleeve, valve body and actuator) can be selected according to your process conditions.

· Full bore - no flow restrictions;
· Closing in the midline - increased sleeve life;
· Only the valve sleeve is in contact with the medium - only one wear spare;
· Self-cleaning function - no jamming;
· There are a variety of valve sleeve materials available to meet the needs of the medium;
· Robust design - extended intervals between repair services;
· The "core" rubber valve sleeve of the pipe clamp valve is the only part of the valve that is in contact with the working medium;
· Customized valve sleeve design, according to the customer's application conditions, select the most suitable valve sleeve structure;
· When the valve reaches its service life, after replacing the valve sleeve, you can get a "nearly new" pipe clamp valve;
