The electric ball valve is an essential component in modern fluid control systems, offering a combination of reliability, efficiency, and automation that makes it ideal for a wide range of industrial applications. By utilizing an electric actuator to control the opening and closing of the valve, this type of ball valve ensures precise and automated fluid regulation, making it a popular choice in industries like oil and gas, water treatment, and HVAC. In this article, we will explore the structure, functionality, advantages, and applications of electric ball valves.
Structure and Working Principle of Electric Ball Valve
An electric ball valve consists of two main parts： the valve body and the electric actuator. The valve body is usually made from materials such as stainless steel or brass, ensuring durability and resistance to corrosion. Inside the valve body, there is a spherical ball with a hole through the center, known as the “ball valve core.” When the valve is fully open, the hole in the ball aligns with the flow path, allowing fluid to pass through. When the valve is closed, the ball rotates to a position that blocks the flow of fluid. The electric actuator, which is the heart of the electric ball valve, is responsible for turning the valve ball. It is powered by an electric motor and typically consists of components such as a gear mechanism, limit switches, and control signals. The actuator can be connected to a control system, receiving electrical signals that instruct it to open, close, or modulate the valve based on the specific needs of the system.
