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.
