Globe valves are specifically designed for throttling applications due to their construction, which allows for better control of fluid flow compared to other valve types. The internal structure of a globe valve features a globe-shaped body that facilitates a more gradual closure. This design enables the valve to regulate flow rates effectively and maintain a steady flow, providing the precision needed for throttling.

In contrast, gate valves are primarily intended for fully open or fully closed positions, making them unsuitable for throttling because they do not provide fine control over flow rates. Ball valves, while allowing for quick on/off control, do not offer the level of adjustment necessary for throttling due to their design that leads to significant flow turbulence when partially opened. Lastly, check valves are used to prevent backflow in a system rather than to control flow, serving a completely different purpose than the throttling function of globe valves.

Therefore, the features of globe valves make them the ideal choice for applications where precise flow control is required.
