Series H

Hy-Grade Series H Flanged End Wafer swing check valves are designed explicitly for flanged, buttwelding and hub ends. The design is the only one to follow a two-piece body design. This design differs from other check valves by incorporating an integrated flapper and pin, providing strength at a critical location. Typical swing check valve designs feature multiple components for the flapper assembly, including bushings, nuts, bolts, and hinge pins. These components wear out over time or come apart, leading to check valve failure.
