What is a ball check valve? 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. If the pump capacity is not sufficient it is possible to choose a lighter ball, and if water hammer occurs when the pump stops, it may be solved by selecting a heavier ball. 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. Salient Features: 1. Lowest possible pressure drop across the valves. 2. 100% leak proof sealing years over years. 3. Non-clogging and self cleaning as ball rotates during operation. 4. Virtually no wear and tear, no maintenance and longer service life. 5. Higher solid handling capacity due to full bore and straight internal path. 6. Lower head loss-high discharge, reduced pumping time-All leading to Energy Saving.
