By analyzing the structure and working principle of the pilot type pressure reducing valve,the appropriate simplification and assumptions were made,the mathematical model was established,the AMESim simulation model of the pilot pressure reducing valve was established by using the HCD hydraulic component library. The model parameters were set up and the static and dynamic characteristics of the valve were simulated and analyzed. The static and dynamic characteristics of the output pressure,flow and so on were analyzed according to the simulation results,and the analysis of the static and dynamic characteristics of the valve was also discussed. The main factors that affect the dynamic and static characteristics of the pilot type pressure reducing valve were discussed,which provides a theoretical basis for the design,selection and maintenance of the pressure reducing valve.
