圧制御装置。[Claims for Utility Model Registration] Consisting of two sets of control valve units each consisting of a plurality of switching valves connected to a supply line connected to an independent hydraulic power source and switched by a pilot signal, each of which belongs to one side control valve unit and the other side control valve unit. In a hydraulic control device that includes a pair of switching valves and a merging switching valve that drives a common actuator, all switching valves close the supply passage in their neutral position, and each control valve unit connects the supply passage and tank. The pair of merging switching valves are controlled by a common pilot signal, and the highest pilot signal among the pilot signals for switching the switching valves including the merging switching valve belonging to each control valve unit is provided. A hydraulic control device comprising a plurality of selection valves that selectively apply pressure to the on-off valve.
