API 594 WAFER CHECK VALVE

API594 Wafer Check Valve Descriptions

API594 wafer check valve is one type of double plate check valve with two torsion springs added to each of pair valve plates, which close the plates quickly and automatically, preventing the mediums from flowing back. API594 wafer check valve can be mounted between the two pipes in both horizontal and vertical directions. We can manufacture the API594 wafer check valve with the face to face dimensions according to API594 with dimensions of 2”~24” (DN50~600mm).
