Hydraulic pump main pump reverse proportional solenoid valve 9314145

The control principle of the proportional solenoid valve has three main aspects: first, the fluctuation of the electrical signal affects the opening degree of the valve; The second is to control the rotation of the valve through the electromagnetic force; The third is to control the opening degree of the valve according to the rotation of the valve, and then pass the feedback signal loop to the flow controller to achieve the control of the flow.
The working process of the proportional solenoid valve can be summarized as four steps. First, the power supply is always stable, and then the proportional control signal is obtained from the controller and transmitted to the proportional solenoid valve; Second, the proportional control signal is converted into electromagnetic force excitation, thereby controlling the rotation of the valve; Third, according to the rotation of the valve to control the opening degree of the valve, and then feedback to the controller; Fourth, according to the feedback signal to adjust the valve spring, so as to achieve accurate control of the valve opening degree. Proportional solenoid valve is an important means of accurate control of flow and pressure, which can achieve fast and accurate flow and pressure control
It is widely used in various hydraulic system control. It uses "position feedback" technology to precisely control the opening degree of the valve, thus achieving outstanding control results, especially in hydraulic applications requiring high quality.
