Abstract

An electromagnetically operated valve, comprises a valve slide with a magnet armature, which is equipped to close a sealing seat in a fluid channel of the valve with a first axial end in a closed position, as well as a sealing element with folded bellows situated between the sealing seat and the first axial end of the valve slide and separates the valve slide from the fluid channel with a fluid-tight seal. The magnet armature is supported in the valve in an essentially non-contact manner due to the fact that the valve slide has a guide pin protruding in the axial direction from the magnetic armature on a second axial end opposite the first axial end, the guide pin being supported to slide in the axial direction; and the valve slide is aligned in the radial direction on a side of the magnet armature facing the first axial end of the valve slide and is supported so it is movable in the axial direction by means of at least one spring element.
