Proquip dual-plate check valves offer a unique compact design with high performance. The special retainerless body and the quick acting spring provide a fast-acting response to flow reversal, minimizing stress and maximizing 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, resulting lower energy loss.
The reduced weight of a dual-plate valve disc versus the full-bodied swing check is a major factor in minimizing slamming and water hammer–making it the optimal solution to ensure system safety. Material selection is fully customizable to meet customers project specifications
