How does the solenoid valve work?

Solenoid valves are well used in many industries, so what is the working principle of solenoid valves?

The working part of the solenoid valve (the solenoid valve is on or off) actually refers to the part of the valve core of the solenoid valve. The valve core is at position A when the solenoid is not plugged in, and at position B when the solenoid is plugged in. When the valve core of the solenoid valve is in a different position, it has the function of connecting or closing each socket on the oil circuit board. For example, a five-position solenoid valve means that the valve core of the solenoid valve has two different working parts (open or closed). It is the opening and closing of the gate valve. Rotary valve. Three-way reversing valve means that there are 2 and 2 lanes on the solenoid valve of the solenoid valve. The five-position rotary valve solenoid valve has a second safety channel that enters the front, which is a common solenoid valve; the five-position three-way reversing valve has two safety channels, one in and two out. Is matched to the connection for open and closed and normally closed. Similarly, pipe joints, three-way ball valves, and three-way valves all refer to the number of liquid safety channels on the oil circuit board.
