Structure & Working Principle:

1. Structure: a valve from the next alloy valve, rubber tubes, the size stem lock, the next column, and other
   derivative component parts.

2.Principle:When smooth transfer vessel,stems size,benefit following the same time led board,compression tube
   sets for closure instead immediately opened.Thus, a guided-lock reciprocation between the opening
and closing valves to complete the work,another for rubber tube or bearing small,closed at the beginning ,
operators when rotating the handwheel is appropriate as long as the conflict reach the opening and closing pole.Never make every effort more support,banned other tools come close.

3:Application:Pinch Valve is used to replace regular valve like butterfly valve, gate valve, ball valve and so on,
it is suitable for water, sewage, oil, slurry, acid or alkaline solution and so on. Especially suitable for thermal
  power plant,  waste-flushing and ash-flushing system of steel plants, with the advantage of anti-abrasive,
scaling preventing, corrosion resistance.

Features

- Full diameter: when tube pinch valve is fully opened, the flow channel is cylinder rubber pipeline, the diameter   is equal to valve nominal diamter, without turn and crack. No eddy, no vibration, no noise and no cavitation. Suitable for high velocity fluid valve

- -Scaling preventing: Valve flow channel is made of rubber, with smooth inside wall, not easy to scaling.Everytime when closing and opening, scaling will be crushed away valve

- - Closing tightly: Rubber flow channel has the advantage of fine wraping cability, valve can been closed tightly even if there is sundries on sealing surface valve

 - Anti-abrasive and corrosion resistance valve

- - No maintance: Rubber channel is the only parts meets fluid, no packing material needed, medium will not corrode other parts of valve. Service life is long, and no need maintance.

Advantages of Manul Pinch Valves:

1. Very Clean	6. Low weight
2. Excellent drainage	7. Easy operation
3. Minimal turbulence	8. Can be used in explosion-proof lines
4. Low airborne contaminants	9. Inexpensive
5. Low maintenance
