The invention relates to an adjustable damping valve device, comprising an actuator with an excitation coil and a valve armature, wherein the valve armature is movably supported in a sleeve-like yoke body, wherein the yoke body has a pole disc on the bottom side, which is arranged position-fixed relative to the valve housing, wherein an emergency operation valve body is switched between an emergency operation state and a normal operation state depending on the power supply of the excitation coil, wherein the emergency operation valve body is switched by a force caused by the magnetic flux of the excitation coil through the yoke body and the pole disc, wherein a magnetic resistance is arranged between the pole disc and the valve housing, wherein the magnetic resistance is generated by an additional magnetic field outside the magnetic field of the excitation coil.
