An electropneumatic magnet valve for a pneumatically actuated field device can include a valve member, an electromagnetic controller, a magnet valve member, and an activator. The valve member can be moveable between at least two operating positions for ventilating and/or exhausting a magnet valve exit. The electromagnetic controller can move the valve member between the operating positions. The magnet valve member operator can move, additionally with respect to the electromagnetic controller, the valve member independently of an operation of the electromagnetic controller. The valve member operator can include an activator to selectively generate/provide a magnetic field for contact free operation of the valve member via which the magnet valve member operator is changeable between a passive operating condition and an active operating condition.
