Abstract: A hydraulic control valve system comprising a hydraulic valve block with a plurality of control valve segments arranged in a juxtaposed manner, each control valve segment comprising a first line, for example a pump line, a second line, for example a return line, and a displaceable valve rod adapted to open and close the first line, respectively close and open the second line to varying degrees depending on a position of the valve rod. The valve system further has a plurality of actuators arranged in a juxtaposed manner, one actuator for each valve segment, each actuator comprising an electrical motor connected to a respective said valve rod through a coupling mechanism.

Each motor has a rotor and a stator, whereby a ratio DS/HS of an average diameter DS of coils of the stator divided by an overall height HS of the coils in a direction parallel to an axis of rotation of the rotor is greater than four.
