摘要： A pilot operated valve device having a plurality of valves for controlling the operation of a hydraulic device such as a hydraulic cylinder, wherein the whole device is compactly formed such that a plurality of valves are mounted in small mounting space without causing them to be interfered by each other. The valve device is provided with an assist for simultaneous application of pressured oil from two hydraulic pumps through the same hydraulic circuit as required. The device comprises a cuboidal valve housing (10); first and second pump ports (11, 12) extending in parallel and horizontally in upper portions near two opposite sides in the valve housing and communicating with a first hydraulic pump; a tank port (13) extending horizontally through the center in the valve housing and communicating with the drain tank; a pilot tank port (25) and an auxiliary pilot tank port that run over and under the above tank port in parallel therewith and in a horizontal direction in the valve housing; first and second auxiliary pump ports (81, 82) extending in parallel and horizontally in lower portions near two opposite sides in the valve housing and communicating with a second hydraulic pump; a plurality of valves (19, 20, 23, 24, 88, 98) inserted in the valve holes formed in the valve housing to open or close these ports; and a plurality of pilot valves (31, 32, 87, 97) for controlling the supply of pressure oil for pilot pressure to these valves.
