式減圧弁。 A valve port is provided between an inlet and an outlet, a valve body is biased by a spring for closing the valve to open and close the valve port, and a valve is provided to open based on a decrease in secondary side pressure. In a pressure reducing valve, the pressure reducing valve is equipped with a pilot valve, and a piston provided so that when the pilot valve opens, primary side pressure fluid is introduced into the upper part of the pilot valve, and the piston is driven by the pressure to open the valve body. A pilot type pressure reducing valve, characterized in that a member for transmitting the driving force of the piston to the valve body is constituted by a member different from the piston.
