API 594 Stainless Steel Check Valve 900LB Dual Disc Lug Type Check Valve

API594 Stainless Steel 900LB Lug type Dual Disc Check Valve

Dual-plate check valves offer a unique compact design with high performance. The special retainerless body and the quick acting spring provide a fast response to flow reversal, minimize the stress and prolong the service life.
The valve is designed with two discs hinged at their sides like a door, eliminating the effect of gravity. Consequently, very little energy is needed to open the valve and maintain this position, so as to minimize the power loss.

Compare to full-bodied swing check, the reduced weight of a dual-plate valve disc is a major factor in minimizing slamming and water hammer. And it's a optimal solution to ensure system safety. Material selection can be choiced to fully meet customers project specifications
