Cast Iron Diaphragm Valve 

Diaphragm valves are flow control devices that offer precision regulation to liquid, gas, and semi-solid slurry flows alike. Diaphragm valves regulate the transport of process streams by sealing process flow lines, either partially or fully, with a flexible membrane that is stretched by an actuator.

If the pressure is high enough, the diaphragm flexes open. As flow drops, there is a lower pressure differential across the valve. If the pressure drops low enough, the diaphragm can flex back to its original closed position. This happens when diaphragm elasticity becomes greater than positive downstream pressure.
