What is the working principle of the solenoid valve coil?

The solenoid valve includes a coil, a magnet, and a ram. When the coil is energized, magnetic is generated, and the magnet attracts the magnet, and the magnet pulls the ram. When the power is turned off, the magnet and the ejector are reset, so that the solenoid valve completes the work process. This is how the solenoid valve works.

Solenoid valves are typically used in hydraulic systems to close and open the oil circuit. In fact, depending on the temperature, pressure, etc. flowing through the medium, such as the pressure and self-flow conditions of the pipeline, there is no pressure. The working principle of the solenoid valve is different. For example, in the self-flow state, zero pressure start is required, that is, after the power is turned on, the coil is entirely sucked up by the brake body. The solenoid valve with a pressure state is a pin that is inserted into the brake body after the coil is energized, and the brake body is jacked up by the pressure of the fluid itself.

The difference between the two methods is that the self-flowing solenoid valve, because the coil has to suck up the entire gate body, so the solenoid valve with a large volume and pressure state only needs to suck the pin, so the volume can be compared. small.
