Threaded Ball Check Valves
Threaded Ball Check Valve
A threaded ball check valve is a check valve that uses a freely moving ball as the closure element. The flow lifts the ball from its seat allowing flow to pass; when flow stops, the ball settles into the seat and prevents backflow. With no shaft or hinge-like moving parts, it does not clog in fibrous and solid-particle-laden fluids.
In addition to ductile iron body threaded models, U-PVC body threaded and solvent socket versions are available for corrosive wastewater. Supplied in sizes from 1″ to 2 1/2″, pressure class PN16.
