Abstract
Actuating device for process valves () comprising a housing (), comprising two housing parts () and an actuating membrane member () sealingly mounted between housing parts () and moveable in strokes which, on the one hand, forms together with the housing a pressurizeable working chamber () and, on the other hand, is loaded by at least one return spring () such that, in the unpressurized state, the actuating membrane member () is brought into a predefined position by means of the pre-tension of the return spring (), wherein the actuating membrane member () is adapted to be connected to a valve shaft () connected to the valve body () of the process valve (). A coupling installation () is provided having coupling parts () arranged on both sides in the direction of the lifting movement of the actuating membrane member (), which coupling parts are adapted to a connection () an the valve shaft () such that the connection of the valve shaft () with the actuating membrane member () is carried out by a one-sided mounting, wherein the valve shaft () is adapted to be connected to each of the coupling parts () of the coupling installation (). On the actuating device () a distance measuring system () is arranged, which comprises a connection () which is adapted to be connected to each of the coupling parts () of the coupling installation () by means of a one-sided mounting, wherein the coupling parts () are constructed in analogy to the corresponding connections () for selectively fastening of the valve shaft () or the distance measuring system () to the coupling installation ().
