Which type of valve is often used for throttling flow in a pipeline?

The globe valve is specifically designed to regulate flow in a pipeline, making it the preferred choice for throttling applications. Its internal design features a movable disk that can be adjusted to control the passage of fluid through the valve, allowing for precise flow control. This capability is what makes globe valves particularly useful in applications where the rate of fluid flow needs to be fine-tuned.

Unlike gate valves, which are primarily designed for on/off service and do not effectively modulate flow, globe valves can be easily adjusted to varying degrees of opening. Similarly, while ball valves can provide tight shut-off, they do not offer the same level of flow regulation due to their structure, which is more suited for fully opened or closed positions. Angle valves, although they can be used in certain throttling applications, are not as effective as globe valves in providing smooth and precise adjustments over a wide range of flow conditions. Thus, for throttling flow in a pipeline, the globe valve stands out as the most appropriate and effective option.
