Heavy Duty High Pressure Pinch Valves Port Size: 15~2000mm

Pinch Valve is a long-lasting and ideal valve, which is specially designed for shut-off and control applications involving abrasive or corrosive slurries, powders, or granular substances.
Technical specifications
Size range: 15~2000mm, A ~84in
Pressure range: 1-10MPa, 1:2 safety factor, which means bursting pressure is 2 times higher than the operating pressure.

Material of valve body
DN15~200 (carbon steel, ductileA iron, aluminum alloy, stainless steel-casting process)
DN250~2000 (45#steel, stainless steel welding technology )
Material of valve sleeve: NR, EPDM, CR(chloroprene rubber), NBR, butyl rubber, FPM, Hypalon rubber.

Working status of pinch valve
Fully-open: the full-bore elastic valve sleeve of pinch valve without any gaps & dead spots.

Center closed: closed on the center line of the valve body, which avoids turbulence and abrasion, as a result, the valve sleeve becomes a smooth and enclosed venturi with self-cleaning during every operation.

Fully-closed: it ensures the pinch valve is with no leakage of two ways when shut off, and the safe design of inner valve sleeve requires no maintenance of sealing elements.
The operating principle of FENGCHI pinch valves is very simple. In the open position, the valve is full bore with no flow restrictions. During closing, two pinch bars squeeze the valve sleeve shut on the center line.
The sleeve is naturally wear resistance and when particles hit the sleeve's rubber surface, the energy is absorbed and released when the rubber bounces back. Heavy duty pinch valves provide bubble tight shut-off even if solids have built up on the sleeve wall. When compressed, any crystallized particles flake off the sleeve surface. The full bore structure ensures free flow of the medium. The construction and materials of the three main components (sleeve, body and actuator) can be tailored to suit your process conditions.
