Abstract
A combined hydraulic integrated control valve block system includes pilot control valve group, control valve subassembly, combination of valve blocks which are connected with external part for installing the pilot control valve group and the control valve subassembly. The pilot control valve group includes multiple pilot control valves and the standard installation surface for the pilot valve is formed on the valve block. The control valve subassembly includes multiple two-way cartridge valve control subassemblies. The valve block is formed with one or two external installation surfaces, the inner side of which has P, T, A and B main channels and multiple pilot control channels.
