Abstract：A linear rotary flow valve with electrical controller is designed, using namely stepping motor as drive,and a good repeatability is achieved. Preliminarily, Matlab is used to fit the overcurrent curves of spool, which could meet spool rotation angle and over a linear relationship between flow area. It will draw three-dimensional simplified model of linear valves with solidworks, then import them to Gambit to mesh. After the convergence and analysis of the opening of the valve flow with the changes over a linear relationship, combined with CFD simulation of flow field on the spool further optimized, it is shown that the valve achieved the linear regulator flow from 10% to 100%.
