Properties:

A valve designed specifically so the diaphragm seals the flow stream from the valve operating mechanism. The flow is controlled by the lifting of the diaphragm from or compressing it against an integral seat. For packless diaphragm valves which utilize a diaphragm as packing and a disk to control the flow, see valve, y.
