Abstract (en)
[origin: EP1347154A2] Valve control comprises an adjustable shaft (1) by which a valve shaft of a valve can be shifted via a transfer chain. The adjustable shaft can be rotated about its axis by a hydraulic drive (12). Preferred Features: The hydraulic drive is a rotating drive, preferably having a stator (13) which is able to rotate via a rotor (16, 17) connected to the adjustable shaft. The stator is cylindrical. Two rotors are arranged separately from each other in the stator.
