Ball check valves
Ball Check Valve – This check valve uses a ball covering a round opening to separate the first and second port. When fluid is drawn in, the ball is pushed forward.
The ball check valve are simple valves who have only one moving part which blocks the reverse flow - a spherical ball.
The full port ball check valve seat is uniquely designed in a way which allows the ball to seat leak-tight the flow without getting wedge into the valve seat.
When the fluid is pushed back, the ball is pressed into the round opening, which creates a seal and allows all fluid to flow out the second port in the intended direction.
Ball check valves are used to prevent return flow in the pipeline transporting waste and sewage water and thick and viscous liquids.
Ball check valves are mostly used to move liquids, since the ball mechanism is not the best for creating an airtight seal. The flanged ball check valve is maintenance free.
