Dual Plate Swing Check Valve

Dual Plate Swing Check Valve

Key Features
  • The product designs are in accordance to ASME B16.34 / API 594 with reliable sealing & sturdy construction to ensure excellent performance.
  • The constructional feature reflects on the compactness of the valve by smaller volume, shorter length & even lighter weight.
  • Suitable for the horizontal & vertical pipe runs.
  • These valves can be provided with soft & metal seat.
  • Various end connections such as wafer / wafer lugged / double flange.
  • Long life & trouble free operation.

The IVDPCV is a spring-loaded Dual Plate check valve uniquely designed for applications. The constructional feature makes the valve much smaller in size, lighter in weight & makes it much more feasible in operation as compared to the conventional swing check valve.

IVDPCV valve employs dual spring-loaded plates/discs hinged on a central hinge pin. It operates on the differential pressure between fluid flow pressure & spring torsion pressure. As the flow pressure reduces, the plates tend to close with a cushion effect by spring torsion force thereby restricting the reversal of fluid flow.
