Abstract
A fluid-operated actuating drive on a valve comprising a base unit () having an electro-fluidic signal converter and a fluidic controller and at least one linear actuator () that can be actuated using the fluidic controller, wherein the gate () of the linear actuator is directly or indirectly coupled to the inlet of the valve. A control unit () is connected to a signal input of the base unit, wherein the signal output is connected to the electro-fluidic signal converter. The actual value signal of a measurement transducer () associated to the valve is fed back to the control unit. A fluidic internal control circuit () is arranged functionally between the signal input and the at least one linear actuator, preferably downstream of the electro-fluidic signal converter.
