            Pinch valve

            Product advantages

            Inner lined with rubber, good resilience, good sealing, no leakage

            Unique rubber processing technology

            Nature rubber content ≥97%

            High resilience, over 76%, super sealing

            Moreover, Dummy club design at the flange

            No need of any sealing devices

            Smooth connection, almost 0 leakage

            Wear-resistant rubber
            Smooth inner surface, low material flow resistance
            Adopts total cross-section design
            Smooth and neat surface
            Low material flow resistance
            Stable and fast liquid flow
            Rarely blockage in real project
            Good elasticity of rubber valve spool, reliable opening and closing

            The valve spool is a soft flexible pipe

            Reliably open and close it through compressed sleeve

            Fast speed can maximumly reduce the wear of soft pipe

            Rubber liner
            Rubber liner, wear-resistant index ≥128%

            The valve spool is independently developed by Xinhai company, made of wear-resistant rubber and its wear-resistance index reaches 128%, service life is 2-4 times of domestic produced rubber, 3—6 times of polyurethane.

            Due to good performance of wear-resistant, pinch valve has long service life and low failure rate. Moreover, it greatly cuts down the maintainence cost by 60%.

            We provide two types of pinch valve:manual control and air-control pinch valve

              Manual pinch valve Air-operated pinch valve
            Controlling technology Manual control Remote control or automatic control
            Working principle Handwheel is rotated Manually instantaneously, which leads the valve rods to driving the upper and lower gate at the same time, compressing the pipe linings, closing it; inversion will be open. Thus, the gate and guide pillar complete the opening and closing work repeatedly. The air pressure or water pressure between valve body and rubber sleeve forces the sleeve to close to cut off the liquid to realize the remote control or automatic control.

            FAQ

            What's the application of pinch valve?
            Automatic control or remote control for all kinds of wear-resistant and non-wear-resistant pipelines
            Uniform addition of reagents in chemical industry or mine
            Very convenient to achieve uniform discharging as discharge valve in mineral processing technology
            Warm tips:
            Pay attention to the following items when you use Pinch valves:
            Not recommended for negative pressure
            Not recommended for severe throttling duties
            The sleeves are designed for pressure to 10.5KG/cm2. If the required pressure is higher than this, please contact us.
