Size range: 15~2000mm, ½~84in.

Pressure range: 1-10MPa, 1:2 safety factor, which means bursting pressure is 2 times higher than the operating pressure.

DN15~200 (carbon steel, ductile 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.

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.
