Hydraulic systems have been widely used due to their high power-to-weight ratio. Despite the growing instances of being superseded by the electromechanical counterparts at low power levels, the market was incapable of presenting alternatives for large-size applications. Additionally, in recent years, the demand for more significant heavy machinery (Mobile & Industrial) has increased, which led to the necessity of even higher flow and pressure Pilot-operated valves, despite the fact that these valves have several issues. One might think the alternative could be developing a hydraulic system that does not rely on Pilot-operated valves, but after decades of research, these systems could not get close to the performance of Pilot-operated Multistage valves. The paper presents a comprehensive study of the progress accomplished from the year 2016 to early 2022 in hydraulic Pilot-operated valves; they are widely employed among ordinary valves, proportional valves, and state-of-the-art digital hydraulics. Higher efficiency will be a primary factor in the success of the new designs. The academia presented several studies to improve the Pilot valves’ performance, but still, they are limited. There are no dramatic developments, and there are only a few upgrades.

“…On energisation of the solenoid coil, [1] the pilot valve opens due to the magnetic force of attraction between the solenoid plunger (which is the integral part of the pilot valve poppet) and armature. Since, the pilot valve port is small, the required load and thereby, the plunger diameter, number of coil ampere turns and power are less compared to a direct acting solenoid valve with a port equal to that of main valve .…”

This paper describes mathematical modeling and analysis of the opening of pilot operated solenoid valve. A series of cold gas thrusters for propellant settling and orientation control of stage before and after the main engine operation. The equations are derived and solved numerically. The mathematical model for electromagnetic and mechanical dynamics is derived by making some simplifying assumptions. It is shown that the behavior of valve in the opening processes. This makes the design complicate and prediction of valve response difficult in traditional methods. It is carrying out a mathematical model to predict the performance of the valve using MATLAB software.A discussion is presented with an explanation of the results and a Comparison of the analysis results with test results of the hardware developed.

This article describes a combination of experimental and mathematical methods for the determination of undissolved air content in hydraulic oil. The experimental part consists of the determination of the oil bulk modulus, considering the influence of undissolved air by means of a volume compression method in a steel pipe. A multiphase model of an oil/undissolved air mixture is subsequently defined using Matlab SimHydraulics software. The multiphase model permits the volume compression of oil and air bubbles independently of each other. Furthermore, time dependencies of pressures are mathematically simulated during the compression of the multiphase mixture of oil and undissolved air for different concentrations of the latter. The undissolved air content is determined by comparing the mathematically simulated and experimentally measured time dependencies of pressure increases. Highlights • Experimental determination of secant bulk modulus and tangent bulk modulus of oil by means of a compression method. • Multiphase mathematical model of compressibilityof oil/undissolved air mixture. • Mathematical simulation and measurement of time dependence of pressure during compression of oil/undissolved air mixture in steel pipe. • Determination of undissolved air content in oil by comparing the mathematical model with the measurement. • The undissolved air concentrations in the measured hydraulic system were determined in the range of 0.22 % to 0.49 %.
