Product Description

Wafer Type Butt-Welded Dual Plate Check Valve

 

Dual Plate Wafer Check Valves work through a disc with a spring that opens when the fluid flows in regular direction; and, when the fluid returns, the spring closes the disc to avoid the passage of the fluid.The most appropriate application of this valve is to absorb backpressure and its consequences.
