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.

Fluid-operated actuating drive on a valve

A fluid-operated actuating drive () on a valve, in particular a shut-off, safety or regulating valve, comprising a base unit () having control valves, two linear actuators () which are located opposite of each other and can be actuated fluidically, and a mechanical converter () which is arranged between the two linear actuators and couples the gates thereof to each other, wherein the outlet of the converter is coupled to the inlet of the valve. To this end, the actuating drive is composed in a modular manner of individual components joined to form a functional unit in the form of the base unit, the two linear actuators and the mechanical converter.
