The Wafer-style series WCV Check valve is an entirely new valve design specifically engineered for water application. The WCV Check valve operates solely on line pressure and back pressure to open and close, no outside energy source is required. As line pressure builds, the elastomeric flapper disc is pushed away, allowing the water to pass.
The memory of the rubber will cause the flapper disc to return flat, and back pressure will seal the flapper against the plate to prevent backflow. The WCV Check valve is designed to be inserted between two mating flanges.
Onyx Valve Company machines all valve castings and parts in-house using the most technologically advanced machines. Every valve component is designed and manufactured to the most accurate machine-tool tolerances.
In addition to fabricating all our valves and pressure sensor ring components in-house, they also design and fabricate all the molds for our rubber components in-house as well.
