It is an actuator and is not limited to hydraulics and pneumatics. It can be used in industrial control systems to control medium direction, flow, speed and other parameters. Therefore, it is widely used in various fields of production.

[0003] A Chinese patent discloses a solenoid valve with the publication number CN214789317U. The article states that "it includes a valve body, a coil assembly and a shell are arranged on the valve body, and also includes a terminal shell and a power cord. The coil assembly is provided with two steel needles, and the two ends of the enameled wire on the coil assembly are respectively wound around the corresponding steel needles. The terminal shell is provided with two connecting holes, one end of the power cord is provided with a connector matching the connecting hole, and the end of the steel needle away from the coil assembly is connected to the corresponding connector. The terminal shell is provided with a slot matching the shell. The valve body is provided with a coil assembly and a shell."
