1. An actuating device (18) for systems (10) with flowing fluid, comprising:
at least one control element (22) being open-loop controlled adjustable between a plurality of operating positions,
at least one regulation element (24) being closed-loop controlled adjustable, and
a controller with a logic (32) for adjusting said control element (22),
wherein said control element (22) and said at least one regulation element (24) are connected in parallel in order to influence the same process variable, and
wherein said controller is set up for adjusting said control element (22) as a function of an operating position of said regulation element (24),
wherein said controller is set up for adjusting, in an open-loop control, said control element (22) in order to generate a closed-loop controlled adjustment of said regulation element (24) back into a target operating range (27), and
wherein said logic (32) for said control element (22) being configured to continue an adjustment of said control element (22) until said regulation element (24) has reached a predefined operating position (33, 35) within a target operating range (27) or passes a predefined operating position (33, 35) into a target operating range (27).
