The dual plate check valve is a swing valve uniquely designed for all purpose non-return valve (NVR) applications.The constructional feature makes the valve much smaller in size, lighter in weight & makes it much feasible in operation as compared to conventional swing check valve.

The dual plate swing check valve employs dual spring loaded plates / disc hinged on a central hinge pine. It operates on the differential pressure between fluid flow pressure & spring torsion pressure. As the flow pressure reduces, the plates tends to close with a cushion effect by spring torsion force thereby restricting the reversal of fluid flow..
