A valve actuating system including a drive device having an axial extension, and having an actuator with an axial output side provided for coupling to a valve and with an opposing axial rear side, wherein the actuator has an attachment interface on the axial rear side thereof for the attachment of an auxiliary device interacting with the actuator, such as a display module, a control head, a position controller or a stroke-limiting module, wherein the attachment interface has a sectional surface onto which the auxiliary device can be tensioned by means of an axial locking device, wherein the axial locking device has a main body and a collar with a locking edge, with which at least one locking element is in contact on the side facing the actuator in order to tension the auxiliary device on the support surface, wherein the collar is formed by a retaining ring secured on the main body.

Valve actuating system

In a valve actuating system having an actuating drive which has a drive housing and an output unit which is movably mounted in the drive housing for generating a stroke of a spindle of a valve for opening or closing a through-flow opening of the valve, wherein the output unit has a force pickup portion to which the spindle is coupleable or coupled and a fastening portion arranged opposite the force pickup portion, wherein the actuating drive furthermore possesses a holder, which is separate from the output unit, has a holder longitudinal-axis and has a fastening device by way of which it is fastened to the fastening portion of the output unit and a support device for supporting at least one position information element on the holder, and wherein the valve actuating system has a plurality of mutually different types of position information elements supported on the holder by way of the support device.

A valve actuation system includes a drive device, equipped with an axial extension, which includes an actuating drive with a drive output side intended for coupling with a valve and an axial rear side opposite this, wherein the actuating drive has on its axial rear side a mounting interface for the attachment of an auxiliary device which interacts with the actuating drive wherein, in order to allow attachment of the particular auxiliary device which is to be mounted, or which is mounted, the mounting interface of the actuating drive is equipped with several different attachment devices which differ in their attachment possibilities and which can be used selectively. In this way, a high degree of variability in the attachment of auxiliary devices is provided.
