Abstract
This paper proposes a flow control system using only pressure meters and the flow coefficients of the valves. To obtain the flow coefficient of a control valve, flow rates for various opening and closing valve angles were first measured and an equation to approximate these values was derived. A valve disk control system was designed to improve the control function by analyzing the characteristics of mechanical friction caused by the movements of the disk. The functionality of the proposed control system was verified by comparing the measured flow rates with predicted flow rates of the proposed method.
