What is the function of a ball valve in a fuel oil system?

In a fuel oil system, the primary function of a ball valve is to control or stop the flow of fuel oil. This type of valve features a spherical ball with a hole through its center, and when the valve is turned, the ball rotates to either allow flow through the hole or block it completely. This design makes ball valves particularly effective for quick shut-off applications, allowing operators to rapidly start or stop the fuel oil flow as needed.

In contrast to other components in the fuel oil system that have different functions—such as regulating pressure, filtering impurities, or monitoring temperature—the ball valve is specifically designed for flow control. This decisive action helps maintain safety and efficiency within the system, ensuring that fuel oil is delivered only when needed and reducing the risk of leaks or spills.
