Abstract：In order to master the basic problems of the flow field distributions of main valve of displacement-electricity feedback cartridge proportional throttle valve，the CFD method was used in the simulation of the three dimensional flow field of main valve of proportion cartridge valve. After the analysis of simulation，the pressure，velocity and streamline distributions were established in different openings of the valve. The flow field distributions were obtained and the energy dissipation location was gotten. The research results provide theoretical basis for the structure optimization.
