GMK Wafer Check Valve

A wafer check valve’s movable disc opens and closes to regulate flow. The compact shape of these valves makes them ideal for use in places where a flanged check valve would be impractical. Wafer check valves have formed bodies around the disc’s orifice. The addition of a valve body, as opposed to the skeleton wafer check, significantly improves the valve’s operation. A flanged check valve’s disc has a small opening in the pipe since the valve is flanged into place. This means the check valve itself may impede flow. However, wafer check valves’ molded bodies allow the disc to swing open all the way, allowing for maximum flow. For obvious reasons, this is crucial if your program needs uninterrupted data transfer. Because of this, we often stock swing check valves for use when a full port valve is needed and wafer check valves for use when the flow is not a concern. A wafer check valve’s movable disc can either allow flow through or close off the valve. They can be installed in places where a flanged check valve would not fit, thanks to their compact shape. Valves made from wafers use molded bodies around the disc’s opening.

Wafer check valves have the following benefits in addition to being more portable, less bulky, and less difficult to store:

  • The disc travels a short distance, reducing the impact force generated by the closure of the valve.
  • When water hammer pressure is reduced, the disc snaps shut more rapidly. When compared to a flange type swing check valve or a flange type lift check valve, these two valves only withstand half as much water hammer pressure.
  • It allows less friction during flow.
  • In both horizontal and vertical orientations, installation is possible.
  • Very little pressure difference at the opening (cracking).
  • Better durability because of decreased water hammer and impact force.



  • Wafer type or lug type
  • Metal to metal seats, soft seats
  • Long-life spring
  • Small size, light in weight, compact in structure, easy in maintenance
  • Two torsion springs are exerted on each of the valve plates, which close the plates quickly and automatically
  • The quick-close action prevents the medium from flowing back and eliminates the water hammer effect
  • The valve is short in length so that it is rigid and easy to mount
  • The valve is tightly sealed with no leakage
  • Low head loss
  • The valve can be installed either horizontally or vertically in the piping
  • Safe and reliable in operation, high interference-resistance
