An electric ball valve is a device used to control the flow of liquids or gases in a pipeline by using an electric actuator to rotate a ball with a hole through its center. The ball inside the valve can rotate a quarter turn (90 degrees) to either allow or block flow through the pipeline, depending on its position. When the hole in the ball is aligned with the pipeline, the valve is open, allowing fluid to pass through. Conversely, when the ball is turned so that the hole is perpendicular to the pipeline, the valve is closed, stopping the flow.

The actuator typically includes a motor and gearing system that ensure precise control over the ball's position. The electric actuator can be controlled remotely or automatically, making it ideal for systems that require automated or remote flow control, such as HVAC systems, water treatment plants, or industrial processes.

One of the advantages of an electric ball valve is its reliability and ease of use. Unlike manual ball valves, which require physical effort to operate, an electric ball valve can be controlled with a switch, a timer, or a programmable controller. This automation saves time and reduces the risk of human error. Additionally, the electric ball valve offers excellent sealing capabilities, reducing the chance of leaks and ensuring efficient operation.

Electric ball valves come in various sizes and materials to suit different applications. They can be made from metals like stainless steel, brass, or plastic materials, depending on the fluid type and operating conditions. This versatility makes them suitable for a wide range of uses, from controlling water flow in residential plumbing systems to handling corrosive chemicals in industrial settings.

In summary, an electric ball valve operates by using an electric actuator to rotate a ball inside the valve, controlling the flow of liquids or gases. Its ability to be automated and controlled remotely, along with its reliable sealing properties, makes it a popular choice in many industrial and commercial applications.
