Check Valve

Valve used to protect piping systems by preventing the reversal of flow and hence is unidirectional.

Typical applications are on the discharge side of a booster where backflow could damage the internals of the equipment and cause an unnecessary shutdown of the system.

Some types also protect pumps from running dry, such as foot-operated check valves that trap liquids in pump suction pipes for lift stations.

These check valve types can be modeled in FluidFlow:

Swing Check Valve
Tilting Disk Check Valve
Piston Operated Check Valve
Spring Loaded Check Valve
Foot Operated Check Valve
