Disclosed is a valve assembly for controlling charging and discharging of a fuel that prevents a high pressure charging pressure from being applied to a solenoid valve during fuel charging. The value assembly includes a transfer flow passage composed of: a charging/discharging flow passage through which the fuel is transferred during charging/discharging of the fuel; a charging flow passage branched from the charging/discharging flow passage and connected to a storage tank, wherein the fuel is transferred through the charging flow passage during charging of the fuel; and a discharging flow passage branched from the charging/discharging flow passage and connected to the storage tank, wherein the fuel is transferred through the discharging flow passage during discharging of the fuel. Further, the value assembly includes a first check valve configured to prevent backflow of the fuel transferred along the charging flow passage; a solenoid valve configured to open or close the discharging flow passage to regulate flow of the fuel; a second check valve configured to prevent backflow of the fuel transferred along the discharging flow passage; and a metering valve configured to control a flow rate of the fuel transferred along the discharging flow passage.
