弁。 A pilot valve is arranged between the primary side passage leading to the primary side and the introduction passage leading to the space above the piston, and the pilot valve is operated by the deflection of the diaphragm, which has the elastic force of a pressure setting spring applied to one side and the secondary side pressure applied to the other side. In a pilot type pressure reducing valve that opens and closes a main valve connected to the piston by driving the valve and controlling the fluid pressure acting on the top surface of the piston by opening and closing the pilot valve, it communicates between the top and bottom surfaces of the piston. A large-diameter communication hole is opened, and a valve body is arranged to open and close the communication hole, and the valve body is arranged to open the communication hole at a low temperature and close it at a high temperature by a temperature responsive member. A pilot type pressure reducing valve characterized by:
