When liquid fows through the valve, the ball is forced into the branch of the valve allowing full fuid fow. When the liquid stops,
equalizing the pressure, the ball drops back into the seat, preventing backfow. Should reverse fow occur, the differential
pressure will cause the ball to seal frmly against the seat preventing leakage.
