ABSTRACT:
This invention relates to the hydraulic control field wherein an electronic controller provides the necessary electrical elements for controlling the movement of an actuator shaft from one pre-selected position to another pre-selected position at a pre-selected velocity and provided with an automatic timing control circuit to sustain the movement or a manual operation to selectively move the actuator. The pre-selected positions and velocities are adjustable over the full range of actuator movement and velocity limit of the hydraulics.
