Analysis of the working principle and function of the pressure reducing valve with pressure limited protective effect is made. A simulation model is built by using the HCD valve hydraulic components library provided by AMESim. According to the structure and size of the actual valve, the parameters of the simulation models are set, and then the simulation analysis of its performance is made. Based on this, the pressure flow characteristics of the pressure reducing valve are measured. The results prove that the experimental results agree well with the simulation results. The simulation of the protective effect of limiting pressure under load mutation is done, and the results show that the effect of the protective effect of limiting pressure is good. It can be concluded that the simulation model established is accurate.
