Ball Check Valve

What is the difference between welded pipe and seamless pipe?

Products PDF

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.

Features

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.

The ball check valves are self-cleaning, as the ball rotates during operation which eliminates the risk of impurities getting stuck on the ball. The standard ball is designed with a NBR rubber lined metal core, and the rubber hardness is optimized to prevent the ball from getting stuck in the seat.
