Ductile Iron Ball Check Valve DIN-F6 DN50-DN400

Ball Check Valve

1. PRODUCT PROFILE

A ball check valve functions by means of a ball that moves up and down inside the valve. The seat is machined to fit the ball, and the chamber is conically shaped to guide the ball into the seat to seal and stop a reverse flow.

Ball check valves are often preferred for use in pumping stations that are rarely attended, since they demand only limited maintenance, typically if the ball makes noise caused by insufficient pump capacity or water hammer.
