The present invention relates to a pressure adjustment valve assembly for a hydrogen storage tank, capable of saving costs and improving performance. The pressure adjustment valve assembly for a hydrogen storage tank integrates and simplifies (reduction from four to three) a connection path and a flow path arranged in a fitting unit. Each component of the inside of a valve housing unit is arranged to correspond to the integration and simplification. The pressure adjustment valve assembly for a hydrogen storage tank includes a valve housing unit (10) and the fitting unit (20). The valve housing unit (10) includes: a hydrogen inlet and outlet (110); a solenoid valve (120) controlling the supply and blockage of hydrogen through the hydrogen inlet and outlet (110); a temperature-sensitive pressure release device (TPRD)(130) releasing the pressure when the hydrogen in a hydrogen storage tank reaches an upper value of high temperature and high pressure; a manual shut-off valve (140) manually operated when a shut-off function of the solenoid valve is lost; a manual unblocking valve (150) manually operated when an unblocking function of the solenoid valve is lost; and a temperature measurement unit (160) measuring the temperature of the hydrogen storage tank. The fitting unit (20) includes: a charging flow path (210) connected to the hydrogen storage tank by being connected to the manual shut-off valve (140) and the solenoid valve (120); a discharge flow path (220) connected to the hydrogen storage tank by being connected to the solenoid valve (120), the TPRD (130), and the manual unblocking valve (150); and a temperature measurement connection path (230) connected to the hydrogen storage tank by including a means for measuring the temperature of the hydrogen storage tank.
