Flow Coefficient Measurement of a Globe Valve for Precision Control

Ji-Won Choi, Soon-Hyeong Park, and Kwon-Hee Lee
Abstract—The globe valve is a linear motion valve that is designed primarily to stop, start, and regulate flow. The disk of a globe valve can be removed totally from the flow path or it can completely close the flow path. In this study, numerical analysis using ANSYS-CFX was initially performed to predict the flow coefficient (Cv), then a prototype model of a globe valve was made. Following the CFD analysis, structural analysis of the valve was performed by applying FSI (Fluid-Structure Interface) analysis. From the analysis results, the fluid flow of water and Cv of the valve were extracted. Based on the numerical results, a prototype design of ultra-fine precision control valve, which can regulate the fluid flow of range 0~0.1 gal /min, was determined. The experimental results were compared with the numerical results using the Cv error index. This study determined the Cv due to the change of disk’s stroke using CFD analysis and experiment.

Index Terms—Flow coefficient (Cv), globe valve, precision control, ANSYS-CFX, numerical analysis.
