Indretning til at drive en dobbeltsædeventil

The device has pistons (K1, K2) selectively connected with coupling elements (36, 37) that are attached with valve disks. Pressure transmission paths (29, 30) are guided into a drive device housing (16) at chambers (31-33) defined by the pistons, where one of the pistons is guided in a sealed manner...

Beschreibung
Zusammenfassung:	The device has pistons (K1, K2) selectively connected with coupling elements (36, 37) that are attached with valve disks. Pressure transmission paths (29, 30) are guided into a drive device housing (16) at chambers (31-33) defined by the pistons, where one of the pistons is guided in a sealed manner and separated from the other piston in the housing. Sealing areas of the pistons define the chambers, and one of the paths for a cleaning cycle of a valve disk (7) is laterally guided transverse to a common axis (X) of the device housing and a valve housing (1) and directly guided into one chamber.
