An electromagnetically actuated valve comprising a valve piston including a first end and an opposite second end, a valve plate at the first end of the valve piston, a spring plate which is fastened to the second end of the valve piston and which has a first planar contact surface, a valve spring that lies against the spring plate and that moves the valve plate into a closed position, and an electromagnet including a coil, an armature pin which has a second planar contact surface that is parallel relative to and that bears against the first planar contact surface, and an armature arranged on the armature pin, wherein the first planar contact surface and the second planar contact surface each have a diameter that is greater than a greatest diameter of the armature pin and a diameter of the second end of the valve piston.
