Dynamic Valve Operation

When fluid is required in the direction of flow, the diaphragm opens allowing exceptional flow. As the flow through the valve stops, the diaphragm closes preventing any return flow. The greater the back or head pressure, the better the diaphragm seals against the valve seat.
