Wafer Butterfly Check Valve
DN:1/2″to 48″
Connect:Wafer
Metal Seat:-29~550℃
Tightness:As per API598

Description

- The check valve disk will be lifted by the pressure of the medium when it comes from the inlet and flow to the outlet.
- When the inlet pressure goes lower than the outlet pressure, the disk will go down by the differential pressure and force of spring and to prevent the flow to return.
