A solenoid valve is an electromechanical device used to control the flow of fluids, such as water, gas, or oil, through a pipeline. It is a type of valve that uses an electric current to open or close the valve mechanism. You can learn more in our comprehensive guide here.
The solenoid valve consists of a coil, a plunger, and a valve seat. The coil is an electrical component that generates a magnetic field when an electric current is passed through it. The plunger is a movable component within the coil that is attracted or repelled by the magnetic field. The valve seat is the opening through which the fluid flows and is blocked or allowed based on the position of the plunger.
When the solenoid valve is energized by applying an electric current, the coil creates a magnetic field that pulls the plunger towards the valve seat, allowing the fluid to flow through the valve. When the electric current is turned off, the magnetic field dissipates, and a spring or other mechanism pushes the plunger back, closing the valve and stopping the flow of fluid.
