What is a Solenoid Valve：Working Principle, Types and Applications

Solenoid valve is a device that controls the flow of fluid by electromagnetic force. It consists of a solenoid coil, an iron core, an iron core winding, a valve spool, a valve seat, a valve stem and so on. It controls the opening and closing of the valve by controlling the current of the solenoid coil, thus regulating the flow of fluid. They are often used in fluid control applications to control water, air, oil or gas.
