The globe valve is specifically designed for modulating or regulating flow in a piping system. Its internal structure consists of a movable disk and a stationary ring seat, which allows for precise control over the flow rate. The flow can be adjusted by changing the position of the disk in relation to the seat, providing fine control that is crucial in applications requiring specific flow rates or pressure conditions.

This capability makes globe valves ideal for throttling or regulating services, as they can effectively manage and maintain flow rates at desired levels. Additionally, their design minimizes turbulence and erosion, enhancing their efficiency in regulating flow compared to other types of valves.

In contrast, ball valves and butterfly valves are primarily designed for on/off applications rather than modulating flow. While they can be used in throttling applications, they do not provide the same level of control and precision as globe valves. Check valves prevent backflow and are not intended for flow regulation at all.
