These valves are designed to prevent reverse flow in systems moving liquid products. When the liquid flows into the inlet, the PTFE ball rolls up into the branch of the valve, allowing full fluid flow. When the flow stops, equalizing the pressure, the ball drops back into the seat, preventing backflow. Should reverse flow occur, the opposing pressure will cause the ball to seat firmly against the gasket, preventing backflow.
