置。 A pressure control valve provided in a pipe that supplies fluid, a pilot valve for setting the low pressure side and high pressure side that sets the operating pressure supplied to the pressure control valve, and a pilot valve for setting the low pressure side and high pressure side. A three-way solenoid valve on the supply side that selectively supplies pressure to one of them, and a three-way solenoid valve on the operating pressure side that supplies the operating pressure of either one of the low pressure side and high pressure side setting pilot valves to the pressure control valve. a timer for supplying a signal to the three-way solenoid valve on the working pressure side to switch the working pressure at a set time; and a delay means for delaying the signal from the timer by a predetermined time and supplying the signal to the three-way solenoid valve on the supply side. Pressure control device consisting of:
