弁のパイロツト弁構造。 A pilot valve is placed between the passage leading to the primary side and the passage leading to the upper surface of the piston, and the pilot valve is driven by the deflection of the diaphragm, which has the elastic force of a pressure setting spring applied to the upper surface and the secondary side pressure applied to the lower surface. In a pilot type pressure reducing valve that opens and closes the main valve port by controlling the fluid pressure acting on the piston by opening and closing the valve, the pilot valve part has a stem guide hole that penetrates the stem guide in the vertical direction. A pilot valve opening is formed at the lower end of the stem guide hole, a pilot valve element for opening and closing the pilot valve opening is arranged from below, and a pilot stem for operating the pilot valve element can be slid into the stem guide hole. A pilot valve structure for a pressure reducing valve, characterized in that the diameter of the pilot stem and stem guide hole is larger than the diameter of the pilot valve port.
