ABSTRACT:
A device for controlling a hydraulic actuator includes an electrically operated valve that controls the flow of a pressure medium in the actuator in response to the operations of three controllers. A first of the controllers designates a position of a piston of the valve. A second of the controllers commands movement of the actuator. And a third of the controllers electronically controls a sequence of movements of the actuator. The three actuators are arranged in a common housing located on the valve.
