Factories around the world that have the ability to design and
manufacture large size pinch valve is very few, for example: Red
Valve, FLOWROX, Jindex, and etc.
As the “core part” of pinch valve, the rubber valve sleeve has high
requirements on the manufacturing capability of the suppliers with
the size increase of pinch valve. It requires not only large-scale
rubber processing and vulcanization equipment, but also a mature
and reliable manufacturing process of valve sleeve, which is the
basis for manufacturing large-size pinch valves.
FENGCHI have these basic conditions to design and manufacture
DN600-DN2000 large-size pinch valves maturely.
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.
Material of valve body：
DN15~200 (carbon steel,ductileiron, 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.
