Thank your for you interest in HY-Grade check valves.

Hy-Grade Valve manufactures precision-engineered Severe Service Check Valves (SSCKV) which are designed to operate in applications where commodity check valves historically fail.  HY-Grade check valves utilize a single-piece disc/shaft assembly which replaces as many as 5-7 components that make up the disc assembly of commodity check valves.

  • Hy-Grade check valves were designed through failure analysis of commodity dual plate and swing check valves.  Typical commodity check valves experince premature failures in the disc assembly.  Hy-Grade replaces these problematic components with a one-piece integral disc and shaft.
