The setting drive has an electric motor (SM) for driving a pair of coaxial cogs (G1,G2), cooperating with a threaded spindle drive (SG) for movement of the valve setting spindle (VS). The motor is controlled by a microprocessor (MP1) comparing the required position with an actual position signal provided by a signal source (PS) using a magnetic rotation angle sensor (M/HS). A battery provides a back-up drive allowing the valve to be moved into one of its end positions.
