The diaphragm (5) comprises a laminate of interleaved diaphragm films and bearing material and is held in place by a beaded metal or nonmetal holding ring (6) acting as a seal in both directions. The O-ring (3), emergency plug (4) and load spring close off the valve to guard against diaphragm damage caused by sudden water escape. The head (1) typically retains all valve parts in place, eg. in central heating systems.
