Rubber sleeve is the most important component for any type of pinch valves, it is the core of pinch valve.
Rubber sleeve provides corrosion & wear resistance, and pressure bearing capacity. The quality of pinch valve is as good as the quality of its sleeve.
Friendly and cost effective frame pinch valves that do not compromise on good quality. We ensure that our pinch valves are manufactured to suit various applications.
Valve sizes are available from 50mm to 350mm. Larger sizes are available on request.
Pinch valves all over the world operate on the same principal and are manufactured with heavy material, therefore making them cumbersome to handle.
Frame Pinch Valves are Built with Cost-Saving in Mind
Frame pinch valves differ from the norm in the sense that they are built from lightweight materials, however, the design takes care of the body strength, and the same principal applies for the wear sleeve.
Lighter built valves require less installation effort in difficult applications, less bracketing on piping, and less transport costs.
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.
We, FENGCHI , have these basic conditions to design and manufacture DN600-DN2000 large-size pinch valves maturely.
The large diameter manual valves and the valves used in high pressure applications come equipped with a reduction gear to ease the operation. Manual valves can also be fitted with a chain wheel and extended stem.
Technical specifications
Size range: 15~2000mm, ~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, 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.
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.
Air operated pinch valve
Without actuators, cost-effective automated control valve, applicable for various kinds of demanding applications.
Technical specifications
Size range: 15~2000mm, -84in
Actuating mode: air or liquid
Operating differential pressure: 2bar
Applicable Media: Powder, Slurry, Particles
The sealed body construction is designed for applications where no leakage of the flowing medium through the valve body is allowed to the environment. The PVS model has proved especially successful in high pressure applications due to the extremely resistant body construction. The sealed body can be equipped with an alarm or piping to ensure that the sleeve rupture can be noticed immediately.Ã?Â
The PVS structure has no rising parts outside the body. The body materials can be chosen from cast iron/mild steel, aluminium or AISI316.
