Abstract: An electromagnetic valve for a pressure container and which includes a manual shut-off of the valve, a stop, and an electromagnetic shut-off of the valve with a sealing element, a magnet coil, a tappet, and a spring element. When the magnet coil has been currentlessly switched and deactivated, the tappet pressed against the sealing element by the spring element presses the sealing element onto a second opening so as to suppress a fluidic connection from the pressure container. Also, when the magnet coil is activated, the tappet can be moved away from the sealing element as far as the stop, such that the fluidic connection can be released.
