Abstract:
The invention relates to a membrane valve (10), in particular for fluid media, comprising a valve body (20), a membrane (22), a pressure piece (44), and a drive (14) for the pressure piece (44). The membrane (22) is coupled to the pressure piece (44) by means of a connecting element (24), said connecting element (24) having a wall (56) which projects from the membrane (22) in the direction of the pressure piece (44) and on which a laterally protruding latching hook (58) is provided on one side and a free space (50) is provided on the other side such that the wall (56) can be deflected in order to connect the latching hook (58) to a corresponding receiving portion (63) on the pressure piece (44). A stationary pin (74) is provided which engages into the free space (50) when the membrane (22) is raised from the valve seat (32) of the valve body (20) and which protrudes out of the free space (50) when the membrane (22) is resting on the valve seat (32).
