Wafer Style Check Valve
Flange Bolts Directly to Pipe Flange
Ideal for Strictly Fluid Applications
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.
- Installation: For horizontal pipe, orient the center rib in vertical position as shown below. For vertical pipe, WCV check valve shall be installed for ‘Flow Up’
