Beschreibung
Zusammenfassung:	An electrical feedback device (6) of a valve (1) is provided for feeding back the position of a hand wheel (4) of the valve (1) and thus the position of a shut-off member of the valve (1). The electrical feedback device (6) can be mounted in a spindle housing (13) of a housing upper part (2) of the valve (1). The electrical feedback device is configured so that the rotational movement of the hand wheel (4) is converted into a linear movement of a trip cam (45). The electrical feedback device (6) has a gearwheel (43) which is driven by a screw thread (42) which is mounted on a ring (41).
