Zusammenfassung:	A diaphragm valve with a drive housing and with a drive subassembly arranged in the drive housing is proposed, for controlling a process fluid by means of a diaphragm. The diaphragm valve comprises a pretensioning subassembly for the arrangement between the drive subassembly and the diaphragm. A first spring element holds the drive subassembly in a pretensioned state before introduction into the drive housing. A second spring element holds the pretensioning subassembly in a pretensioned state before introduction into the drive housing.
