The Hydraulic valve used in construction machinery features at notches on its spool for obtaining desired operation performance. Because of the special structure of the spoo1, the valve has different characteristics from the traditional spool valve. This paper uses CFD to simulate the flow state in valve as the spool at various positions and so to obtain the flow and flow force characteristics. To make the flow analysis more effectively, an assembling styled modeling method based on uncontinious mesh is proposed. The comparison between the experiment and analysis results shows the analysis results are satisfactory.
