Abstract: 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.

Abstract: 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.
