An apparatus for attachment of hydraulic valves for controlling working devices of heavy equipment is provided, which can reduce a lead time for attaching and assembling a main control valve, an accessory valve, and valve blocks for jointly connecting the respective valves with hydraulic piping, to an upper swing structure. The apparatus includes a lower driving structure and an upper swing structure, a cabin and an engine room, working devices fixed to the upper swing structure, a main control valve shifted in accordance with an operation signal from an operation lever and including spools for controlling a supply amount and a flow direction of hydraulic fluid fed to the corresponding working devices, a sub-plate attached to a specified position of the upper swing structure, an accessory valve installed on the sub-plate and controlling hydraulic fluid fed to the main control valve, and valve blocks installed on the sub-plate and jointly connecting the main control valve and the accessory valve with hydraulic pipes. The sub-plate is attached to the upper swing structure after the main control valve, the accessory valve, and the valve blocks are installed on the sub-plate, and the respective valves are connected with the hydraulic piping.
