Magnetic valve with manual override

A magnetic valve with a manual override, through the operating element of which a magnetic core, which serves as a valve element or that is connected to a valve element, can be shifted from an off position into an operating position without excitation of a magnetic coil system as assigned to it, and with detection means for detection of the position of the magnetic core that is held in the operating position by the manual override, characterized by the fact that as a detection means there is provided a coil current monitoring device that monitors the rise of coil current after switching on the magnetic coil system, which has a detection device for detection of the absence of a drop in current produced by movement of the magnetic core after being switched on and a signaling device for electrical signaling of a position of the magnetic core held in the operating position by the manual override when a said drop in current is absent.
