In a pilot type pressure reducing valve that controls the fluid pressure acting on a main valve such as a piston valve by opening and closing the valve, the pilot valve is controlled by a vertical hole that penetrates vertically and is connected to a passage that leads laterally to the top surface of the piston. A horizontal hole is formed in the vertical hole, a valve seat surface is formed at the lower end of the vertical hole to form a pilot valve opening, and a pilot valve stem is placed in the vertical hole and a plurality of balls formed slightly smaller than the diameter of the vertical hole are formed on the vertical hole. is arranged, and a pilot valve body is formed at the lower end of the pilot valve stem to open and close the pilot valve port by seating and separating from the valve seat surface from below,
A pilot type pressure reducing valve in which a pilot valve body is biased from below in the valve closing direction by a spring, and the flexure of a diaphragm is applied to the uppermost ball.
