Pan Check Valve
Feature
No water hammering effect
There is no water hammering effect since the valve is closed by spring before water backflow takes place.
Thin, Small and Light Structure
PAN Check Valves have much shorter length and lighter than those of swing or lift check valves bacause the disc stroke is short and body has no flange.
Either Horizontal or Vertical Installation
PAN Check Valves can be horizontally or vertically installed bacause of their spring compression structure.
Free alteration of opening pressure
Alteration of opening pressure is available upon customer’s request.
Notice
Please contact us when the valve is used in high pressure and temperature.
Please contact us when the valve is used in excessively freguent open and close condition.

Center Rubber how to use
When four points of center rubbers have simultaneous contact with four bolts, it is properly centered.
Notice
Please only use for in-compressible fluid.
