Swing Check Valves

In clean water and wastewater applications, all pumping systems require a check valve to prevent reverse flow when the pump is not in operation. Check valves operate automatically, require no external power or control signal and operate from the change in flow direction.

The selected check valve should also have a long life, nonslam closure, low head loss and low leakage. While there are many types of waterworks check valves including silent checks, double discs, swing checks, ball checks and tilted discs, historically the swing check valve has been the most prevalent.
