Beschreibung
Zusammenfassung:	A globe valve for a refrigeration circuit or air-conditioning circuit of a motor vehicle, with a drive unit (12), a valve body (66) which is operatively connected to the drive unit (12) and can be moved translationally between different positions in the case of an actuation of the drive unit (12), a valve seat (68) which delimits a throughflow cross section together with the valve body (66), and a sensor device (82) which comprises a stroke sensor (83), wherein the stroke sensor (83) interacts with a permanent magnet (86) which can be moved translationally together with the valve body (66) by the drive unit (12), wherein an additional permanent magnet (88) is arranged rigidly in the region of the stroke sensor (83) in such a way that the stroke sensor (83) detects an overlap of the magnetic field of the permanent magnet (86) which can be moved translationally together with the valve body (66) and the magnetic field of the additional permanent magnet (88).
