Solenoid valves are electrically controlled devices that regulate the flow of fluid or gas in a system. They are essential in various applications, from industrial machinery to household appliances, where precise control of the fluid is required. These valves consist of a coil, plunger, and an actuator that opens or closes the valve when an electrical current is applied. Solenoid valves offer significant advantages, such as fast response times, high accuracy, and the ability to control large volumes of fluids with minimal energy consumption.
