What is the purpose of using a globe valve in a piping system?

A globe valve is specifically designed to control the flow of fluid through a piping system. It achieves this by utilizing a spherical body that has an internal baffle, allowing for a changeable flow area when the valve is opened or closed. This design enables precise regulation of flow rates, making it an ideal option for applications where flow control is essential. Globe valves can be adjusted incrementally, providing operators with the ability to finely tune the flow according to system requirements.

In addition to its primary function of flow regulation, globe valves also offer advantages such as good throttling capabilities and a relatively compact design compared to other valve types. This regulation feature is crucial in situations where maintaining specific pressure and flow levels is necessary for system efficiency and safety.

Other options, while related to different valve functions, do not accurately represent the primary purpose of a globe valve. For example, valves designed for quick shut-off typically include ball or butterfly valves for rapid closure. Isolation valves, meanwhile, can serve to separate sections of a piping system but may not provide the same flow control capabilities as a globe valve. Similarly, globe valves are not favored for connecting different pipe sizes, as other types of fittings and valves are more suitable for that purpose.
