Abstract

A diaphragm valve having a movable diaphragm (20) configured as a closure element has a valve housing (6) and an actuator (8), the diaphragm (20) being clamped between a flange (18) of the valve housing and a base (10) of the actuator (8) and being provided with a first identification means (32) in which data which are adapted to be read out wirelessly are stored. A further identification means (50, 56) is also fastened to the flange (18) and/or the base (10). The read-out surfaces of the further identification means (50, 56) are substantially at right angles to the read-out surface of the identification means (32) on the diaphragm (20).
