Increasing use of hydraulic control valves (HCVs) in industry has led to development of a high potential research area for studying them. Applied magnetic materials in proportional solenoids (PSs) of HCVs have remarkable effects on magnetic force. The main idea of this paper is to investigate the effects of different magnetic materials used in the PS's core and plunger, on the dynamic behavior of the PS and to obtain their importance levels. This helps to choose the proper materials that improve the performance characteristics of the PS. Different combinations of magnetic materials with their non‐linear B‐H curves have been applied in ANSYS software package to determine the magnetic behaviors (magnetic force, magnetic flux density) of the materials. Magnetic force‐displacement curves are obtained for the different combinations of the materials by finite element analysis (FEA), based on them the dynamic behavior of the PS can be studied without constructing a physical prototype. The Magnetic flux density and force are also calculated using finite element method (FEM) and the results have been compared with the experimental results obtained from an actual PS.
