A device that controls the flow of a fluid or gas within a system through an electrically actuated mechanism, allowing passage in either an open or closed state. This type of valve typically features two ports: an inlet and an outlet. When energized, the internal components shift to either allow unobstructed passage or to completely block flow, depending on the default state (normally open or normally closed). For example, in a home heating system, this component might regulate the circulation of hot water based on a signal from the thermostat.
The advantages of using this technology include remote operation, precise control, and automated system management. Historically, manual valves were the primary method for regulating flow; however, the development of electrically controlled alternatives has enabled greater efficiency, improved safety, and integration with advanced control systems. Its importance stems from its ability to automate processes, reduce manual labor, and optimize system performance in various applications.
