Solenoid Valves

A solenoid valve basically works by using electricity to control the flow of stuff like liquids or gases. Its an electromechanical thing, meaning it has mechanical parts that get moved by an electric current going through this coil called a solenoid. The coil creates a magnetic field or something that opens or closes the valve automatically, I guess thats the main idea. Sometimes it feels a bit confusing how the current turns into that action, but yeah, it does it without needing manual help.
