A Mini Solenoid Valve is a type of electromechanical valve that uses an electromagnetic coil to control the opening and closing of a valve. When electric current passes through the solenoid, it generates a magnetic field that actuates the valve, allowing it to either block or allow fluid flow. The "mini" aspect refers to the valve's small, compact size, which is particularly beneficial in applications where space is limited or when a lightweight solution is necessary. Mini Solenoid Valves are commonly used for controlling air, gas, water, or other fluids in various systems.
