What is the function of the solenoid valve coil?

The coil is an important part of the solenoid valve, so what role does the solenoid valve coil play in the actual production process?

The movable iron core in the solenoid valve coil is attracted by the coil when the valve is energized and moves, driving the valve core to move, thereby changing the conduction state of the valve; the so-called dry or wet only refers to the working environment of the coil, and has no major impact on the valve action. the difference. However, we know that the inductance of an air-core coil is different from the inductance after adding an iron core to the coil. The former should be small while the latter is large. Similarly, when the same coil is applied with alternating current of the same frequency, the inductance will vary with the position of the iron core, that is, its impedance will vary with the position of the iron core. When the impedance is small, the current flowing through the coil will increase.

The above is the role of the solenoid valve coil.
