Abstract
A device for controlling movement of a load. The device includes a first conduit, designed to be connected to a first chamber of a hydraulic actuator, a second conduit designed to be connected to a second chamber of the hydraulic actuator, a first balancing valve, positioned along the first conduit, which is normally closed and is actuated towards an open position by the pressure present in the second conduit, a second balancing valve, positioned along the second conduit, which is normally closed and is controlled towards an open position by the pressure present in the first conduit, and a third balancing valve, positioned along the first conduit, which is normally closed and is actuated towards an open position by the pressure present in the second conduit.
