Check Valve Design . An essential element in the design of water and wastewater pumping systems is the proper selection of the pump discharge check valve, whose purpose is to automatically open to allow forward flow and automatically return to the closed position to prevent reverse flow when the pump is not in operation. As the inlet pressure increases, it pushes up on a disc (overcoming gravity and/or a spring) to allow media to flow through.

The forging process is carried out in strict accordance with the forging process regulations and process cards. When the flow decreases, the plates close by the action of torsion spring before flow reversal takes place. These function in a manner similar to ball check valves, allowing for flow as long as flow pressure remains steady, but applying gravitational closure.

The media then flows around the disc, through the channels and out through the. A tilting disc check valve has its pivot point at the center of the disc so that the fluid flows over the top and bottom of the disc. The following are various codes and standards that govern check valves and their connections. Closure of the disc is caused by gravity pulling the disc and the
