Abstract

PURPOSE: To control the pressure of fluid in excellent manner, by providing the pressure control valve different in the flow control range in the main and the branch pipes and selectively operating the pressure control valve in matching with the flow passed.
CONSTITUTION: The pressure control valve 4 of a large capacity is provided to the main pipe 2 and the pressure control valve 5 of a small capacity is with the branch tube 3. The detection sections 6 and 7 detecting the opening of the valve detect the displacement if the valve shafts 4b and 5b as the change in the resistance valve. This output is converted into a voltage signal at the resistance-voltage converters 15 and 16. The converters 15 and 16 are selected with the signal of the selector switch 17 and one output is fed to the relay unit 18 alternatively. The unit 18 closes the electromagnetic valve 19 and opens the valve 20, when the valve opening of the valve 4 receiving the valve opening signal from either one of the converters 15 and 16 is substantially at a minimum valve opening, and it closes the valve 20 and opens the valve 19 when at maximum opening. Thus, by operating the pressure control valve in matching with the flow control range with opening, the pressure of fluid can be controlled in excellent manner.
