A selection valve for selectively supplying pilot hydraulic pressure to a plurality of control valves includes a valve body having an upstream oil hole communicating with the pilot hydraulic pressure source and a downstream oil hole communicating with the control valve; a valve spool that is slidably inserted into the valve spool and has a pressure oil chamber therein that can communicate with the upstream oil hole and the downstream oil hole, and the hydraulic pressure generated in the valve spool by the pilot oil pressure. A pilot actuated selection valve characterized in that a balancing oil hole communicating with the pressure oil chamber is formed in the valve spool in order to offset unbalanced force.
