Introduction video of Wafer Check Valve :   

GZP Wafer Check Valves are manufactured to the latest edition of API 594/API 6D and tested to API 598.All valves from GZP VALVE are strictly 100%tested before shipment to guarantee zero leakage.

Wafer Check Valve is also called reflux valve, backpressure valve and one way valve. This type of valves is opened and closed by the force of the flow of media through the pipe. It's an automatic valve. They are widely applied in petroleum, chemical, textile, power, marine, metallurgy, etc.

Wafer Check Valve is made up by body, plate, stem, and spring etc. Use wafer, flange, lug connection. Because its structure length is shorter than the general check valve, it is most suitable for places with limited installation space. Plate has short closing stroke with can significantly reduce water hammer pressure.

 The main construction features of GZP wafer check valve are following:

  1. Single plate and double plate design are available.
  2. The sealing surface can be surfacing wear resistant material or rubber lining.
  3. The plate has short closing stroke and spring loading, which can significantly reduce water hammer pressure
