Technical Specifications
Advantages of Woke Pinch Valve 
Woke pinch valve has smooth media and minimal frictional resistance. Without any leakage nor blockage
it is highlighted in its long service life, easy maintenance, and favorable price.
   Working Pressure
Maximum 5 bar (medium pressure)
Control Pressure
The effective working pressure is approximately +2.5-4.0 bar (closure pressure). If the control or closing pressure is too high, service life of the sleeve may be shortened. The pressure must be no more than 2.5-4.0 bar of the working pressure.
Differential Pressure
The control pressure is not greater than the maximum operating pressure of 2.5-4.0 bar; depending on the rated size and sleeve material.
Control Medium 
Compressed air, neutral gas, water (oil, please consult us before use)
Temperature Range
Each sleeve material has its own specific temperature range, allowing an ambient temperature of -20°C to +80°C.
Mounting Position
It can be mounted in any position, and it is suggested the bulk goods be installed vertically. If installed horizontally, the control connection shall be installed upward.
Function
Woke pinch valves are pressure control valves. If there is no pressure, they are normally open. If there is pressure, the valves will be closed.
Closing Features
Woke pinch valve is suitable for medium like sealing gas, liquid, solid and powder. A highly elastic sleeve can enclose any solid and does not guarantee tightness if the fluid consists primarily of particles.

Precautions
Independent research and development · Durable
 Be sure to turn off the gas supply and disconnect the control gas before replacing the inner bushing, cleaning the pinch valve or performing any other operations.
 Be sure to keep the body, tools or other objects from the pinch valve when it is running.
Do not touch the pinch valve when the medium is transported at a high temperature. (There is a danger of causing burns)
 The pinch valve can only be disassembled when the device has been shut down and is in a no-pressure state.
 In order to prevent the maximum allowable working pressure/control pressure overload of the pinch valve, the equipment must be equipped with a pressure limiter and a safety valve.
 Unstable gas" can not be used as working medium.
 Please note that there is a possibility of static electricity (explosion hazard) depending on the application medium or the environment in which the pinch valve is applied.
 When selecting the pinch valve material, you need to consider not only the service life of the valve itself but also the driving components (such as gas circuit control, solenoid valve, etc.), because once the inner bushing is damaged, the medium may enter the control circuit.
