  "textContent": "The invention relates to a valve assembly (12) for a control valve (10), comprising a valve body (14) including a central longitudinal axis (L), the valve body (14) comprising a cavity (18) with a fluid inlet portion (42) and a fluid outlet portion (40), a valve needle (20) axially movable in the cavity (18), the valve needle (20) preventing a fluid flow through the fluid outlet portion (40) in a closing position and releasing the fluid flow through the fluid outlet portion (40) in further positions, and an electro-magnetic actuator unit (36). The electro-magnetic actuator unit (36) is designed to actuate the valve needle (20). The electro-magnetic actuator unit (36) comprises a pole piece (30) being fixedly arranged relative to the valve body (14), and an armature (28) being coupled to the valve needle (20) and being axially movable in the cavity (18) . The electro-magnetic actuator unit (36) comprises a permanent magnet (50) which is coupled to the valve body (14) and which is arranged in a position in that the permanent magnet (50) exerts a force on the armature (28) acting to contribute to move the valve needle (20) into the closing position.",
