ABSTRACT: In hydraulic systems, the flow control valve is mainly used to regulate the speed of the output node of the hydraulic motor by changing the passage space of the fluid in the valve. However, the inlet and outlet pressures of the valve do not always remain constant. Any change in pressure will change the flow rate of the fluid passing through the valve and therefore will change the speed of the hydraulic motor. Pressure compensated flow control valves are often used in hydraulic systems when precise speed control is required under varying pressures due to load variation. Since for all industrial processes where hydraulic power plants are used, the presence of a stable state of the working characteristic of the hydraulic motor is necessary, we studied the pressure-compensated flow regulating valve with the aim of building a mathematical model and after a simulation program, through which will simulate the working characteristics of the valve and by combining experimental data we can improve the characteristic of this component by changing its constructive elements.
