とよりなる構成の圧力制御装置。A pressure control valve is installed in the middle of the piping and operates under the control of a pilot valve to keep the pressure on the downstream side constant, and a pressure control valve is installed in the middle of the branch piping that branches from the upstream side of the pressure control valve and reaches the pressure supply port of the pilot valve. The pilot pressure control valve operates by supplying the pressure on the downstream side of the pressure control valve to the diaphragm chamber on the spring case side thereof, and outputs a pilot supply pressure at which the differential pressure with the pressure on the downstream side of the pressure control valve is constant. A pressure control device consisting of:
