摘要：A device for a valve actuator is described, the valve actuator being provided witha slide nut surrounding a portion of an actuator slide and being in engagement with anexternal threaded portion arranged on the actuator slide, the slide nut being axially fixed

relative to the actuator slide, and the actuator slide being in rotation-preventingengagement with a portion of an actuator mounting or a valve housing, and the slide nutbeing connected to a driving motor via transmission means. Also, a method of operating avalve is described, the method including the step of: providing an axial displacement ofthe actuator slide by rotating a slide nut which surrounds a portion of an actuator slide, isin engagement with an external threaded portion arranged on the actuator slide and isaxially fixed relative to the actuator slide, the rotation being provided with the help of atleast one driving motor.
