A solenoid valve works by using an electromagnetic coil to generate a magnetic field when an electric current is passed through it. This magnetic field pulls a plunger or armature inside the valve, which opens or closes the valve. When the valve is closed, the plunger seals off the flow of fluid or gas through the valve. When the valve is open, the plunger allows the fluid or gas to flow through the valve. Solenoid valves are commonly used in various applications to control the flow of liquids or gases.
