Abstract

A valve (1) with a position-measuring system, comprising a control valve for regulating a flow of a process fluid and comprising a drive (60) and also a yoke (30) for connecting the drive (60) to the valve (1), comprising a control rod (50), which is linearly movable within the yoke (30), and comprising a measuring device (10) having at least one magnet-sensitive sensor (22) and at least one magnet (102). The magnet (102) is fastened to the control rod (50) by means of a magnet holder (100) and the sensor (22) is fastened to the yoke (30) by means of a sensor module (20). The magnet holder (100) has an adjusting element (104), which is of a shape that complements a receiving portion on the control rod in such a way that a magnet holder (100) arranged on the control rod (50) by means of the adjusting element (104) and the receiving portion is axially fixed, with the sensor (22) and the magnet (102) being in line, wherein the magnet holder (100) has two opposing legs (105), which span an opening width corresponding to the diameter of the control rod, so as to allow the control rod to be introduced radially into the magnet holder (100).
