御装置。A pressure control valve arranged in a fluid piping, a pilot valve for setting the valve opening degree of the pressure control valve, and a pilot valve operated to variably set the downstream pressure of the pressure control valve. A secondary side pressure variable setting means that variably sets the valve opening of the pressure control valve and outputs a set valve opening signal corresponding to the set valve opening; and a secondary side pressure variable setting means that detects the actual secondary side pressure and sets the pressure. A pressure detector that outputs a signal, a pressure signal from the pressure detector after waiting for the variably set secondary pressure to stabilize, and a set valve opening signal from the secondary pressure variable setting means. A pressure control device comprising a control circuit that finely adjusts the variable secondary pressure setting means so that the secondary pressure becomes a pressure to be set based on the secondary pressure.
