What is the working principle of an electromagnetic overflow valve?

Working principle of an electromagnetic overflow valve: When the electromagnetic overflow valve operates, it uses the pressure of the spring to regulate and control the pressure of the hydraulic oil. When the pressure of the hydraulic oil is less than the required working pressure, the valve core is pressed by the spring against the inlet of the hydraulic oil. The greater the pressure of the hydraulic oil, the higher the valve core is lifted by the hydraulic oil. Below is the structural composition of an electromagnetic overflow valve: 1. The electromagnetic overflow valve mainly consists of a valve body, valve core, spring, and adjusting screw. 2. Spherical valves are used in low-pressure, small-flow hydraulic systems. 3. Conical valves are used in higher-pressure, small-flow hydraulic systems, and the sealing effect of the conical valve core is better than that of the spherical valve. 4. The function of the overflow valve is to prevent the pressure of the hydraulic oil in the hydraulic system from exceeding the rated load, providing a safety protection role.
