Which valve design is referenced as suitable for throttling purposes?

The globe valve is recognized as particularly suitable for throttling purposes due to its unique design that allows for fine control of flow rates. Unlike other valve types, the globe valve features a spherical body with a movable plug or disk and a seat that together facilitate a more variable flow. This enables adjustments to be made with precision, making it effective for controlling the flow of fluids in a system.

When a globe valve is partially opened, its design allows for a significant reduction in flow area, which enhances the ability to regulate the flow as required in various applications. This is crucial in situations where consistent adjustments are necessary to maintain desired operational parameters in a system, such as in heating, cooling, or even fluid transfer operations.

Other options, such as ball valves and plug valves, are primarily designed for on/off operations and, although they can be used for throttling, they are not as effective at providing precise control as globe valves. Check valves serve an entirely different purpose, ensuring one-directional flow and do not offer throttling capabilities. Thus, the globe valve stands out as the optimal design for applications requiring throttling.
