制御装置。A pilot valve device detects the output fluid pressure from a main valve device through which a fluid whose pressure is to be controlled passes, and adjusts the opening degree of the main valve device according to the difference between the detected pressure and the set pressure. In the fluid control device, the pilot valve device includes a diaphragm on which a gas pressure corresponding to the set pressure applied from a gas pressure regulator and the detected pressure act in opposite directions; A gas tank is provided in the gas pressure supply path between the gas pressure regulator and the pilot valve device, and includes a control valve for controlling the valve device, and has a volume sufficiently larger than the volume change on the gas pressure supply side due to the operation of the diaphragm. A fluid pressure control device characterized in that:
