Dual Plate Wafer Check Valve is defined as a mechanical device that allows a one directional fluid's flow. 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, as well as irrigation residues. The design in BOV'S Dual Plate Wafer Check Valves offer a lot of advantages in comparison with other check valves. Their compact size allows it to work as efficiently as any other.
