Wafer Check Valve

Use our Part Number Search.

A wafer check valve is a general purpose or high-performance check valve with a short face-to-face design.  Unlike swing check valves, these valves are typically flangeless, installed between two flanges on the inside diameter of the flange bolt circle, held in place by studs.  Spring tension can be customized to accommodate low, minimum, standard, or high torque springs.  Additionally, seating surfaces of a wafer check valve can be specified to meet service demands with such materials as Buna-N, Viton, Teflon, Neoprene, EPDM, and Hypalon for bubble-tight seating.  For more information on this product or others, such as the stainless steel angle valve or the Hills McCanna pump, please contact Authorized Parts.  Can't find what you need?
