Abstract
A diaphragm valve has a drive assembly and a fitting through which a fluid can flow which has a diaphragm mounted to the drive assembly. A drive unit has a pressure piece which can be displaced in a direction of stroke (A) of the diaphragm valve and which is adapted to be coupled in a nondestructively detachable manner to a lock structure on a diaphragm to move the diaphragm, and a locking unit for connecting the fitting to the drive unit. The locking unit comprises a lock hook which is pivotably mounted to the pressure piece and can assume an open and a closed position, and a pneumatically moved actuating element which acts on the lock hook to move the latter into the closed and/or open position, wherein in the closed position, the lock hook engages the lock structure on the diaphragm.
