A system that does not include a pressure reducing valve (hereinafter referred to as a second system) houses a pressure reducing valve that reduces and outputs the pressure of the
In the pressure reducing valve for two systems, the piston is moved to the failure side to stop the pressure reducing action of the pressure reducing valve when the system (referred to as a system) fails, and the pressure reducing valve is configured such that: It has a large diameter part, a small diameter part that protrudes liquid-tightly into the atmosphere, and a valve part, and receives input pressure in the direction opposite to the output pressure at the step between the large diameter part and the small diameter part, and A sliding hydraulic plunger; and a fixed valve seat that opens and closes communication between the input pressure and the output pressure by separating from the valve portion of the hydraulic plunger, and when the second system fails. The hydraulic response plunger and the fixed valve seat are moved together with the piston to the second system side, and the distance that the hydraulic response plunger can move in the valve closing direction is determined by the distance necessary for the valve part to come into contact with the fixed valve seat. A two-system pressure reducing valve with a bypass function configured to prevent the pressure reducing valve from closing and thereby stop the pressure reducing action.
