A pilot relief valve based on a low-power proportional solenoid was developed. Considering the nonlinear factors of hydrokinetic, dynamic process of main and pilot valve spools, fluid flow equations of the orifices and fluid compressible equations,a mathematical model of the proposed valve was established and analyzed by the simulation software of Simulink, and the influence of low-power proportional solenoid’s structure and performance parameters on steady-state control characteristics was discussed.The simulation results accord with the experimental ones,show that the proposed valve has excellent stable control and load characteristics, low steady-state power consumption of 8.1W, low temperature rise of stator coil.
