Pressure Seal Swing Check Valve



Pressure Seal Swing Check Valves designed for fast check valve action with maximum service life in the compact pressure seal configuration.

  • Uncomplicated design has segment retaining ring and mild steel silver plated (or graphite) gasket to aid disassembly and provide maximum bonnet seal
  • Reliable Operation – Valves are designed to close quickly with positive shutoff in either horizontal or vertical (flow up) pipe runs. The body seat ring is installed on a 3° angle. This allows our swing check valve to close completely even when installed in a horizontal pipe run with no flow.
  • Easy Maintenance – Our bolted bonnet design is simple to disassemble, easy to maintain. For example, our threaded seat rings are easily accessible for repair or replacement.
  • Long Life – Our rugged hinge pin/hinge and disc construction is designed to withstand the shock of quick closing and provides years of service. Anti-rotation lugs on discs extend service life in turbulent, high velocity services which can otherwise cause spinning and wear.
