。A poppet that presses against the valve seat with a spring 20 provided in a spring chamber is interposed between the primary passage leading to the supply passage of the hydraulic actuator and the discharge passage of the hydraulic actuator. An adjustment chamber is provided in the middle of an oil path that is inserted into the spring chamber by a shaft portion having a cross-sectional area smaller than the area and that connects the discharge path and the spring chamber to accommodate a piston so as to be able to reciprocate. A relief valve for a brake valve, characterized in that it is pressed against one end of the piston to close the oil passage on the discharge passage side, and that the adjustment chamber and the spring chamber are always in communication regardless of movement of the piston.
