ABSTRACT:
An electrically controlled hydraulic remote controller for use in piloting the operation of a hydraulic control valve comprising a pair of electrically operated three-way pressure control valves. Each control valve has a supply pressure inlet and a controlled pressure outlet operable in the de-energized position to prevent flow from the supply inlet to said controlled pressure outlet and connect said outlet to tank pressure. Each valve when energized is operable to permit fluid flow from the inlet to the controlled pressure outlet in proportion to the solenoid force operating said valve and simultaneously permit fluid to flow to tank pressure. The controller is responsive to the higher of the controlled pressure of the outlets of the two pressure controlled valves for applying the higher controlled pressure to the valve having the lower controlled pressure to operate the valve in direction increasing the passage of fluid through the other valve to tank.
