The purpose of the present invention is to provide a hydraulic valve device which can supply oil to a hydraulic clutch by stably receiving oil through a different oil source without direct connection to a hydraulic pump. The hydraulic valve device, which is mounted on a transmission of a work vehicle and supplies oil to a hydraulic clutch of the transmission, comprises: a valve block including an oil inlet formed at the top, a plurality of valve mounting grooves which communicate with the oil inlet and are formed at the bottom to face the oil inlet, and a plurality of oil outlets formed on the inner surface to correspond to the respective valve mounting grooves; an accumulator located between an oil source and the oil inlet; and a plurality of hydraulic control valves mounted on the lower part of the valve block in the valve mounting grooves.
