Which valve is most suitable for throttling flow?

The globe valve is most suitable for throttling flow due to its design, which features a movable disk and a stationary ring seat. This configuration allows for precise control of flow rates, making it effective for applications that require varying degrees of flow regulation. When partially opened, the globe valve can significantly restrict flow, allowing operators to achieve desired flow rates with greater accuracy compared to other valve types.

In contrast, the gate valve is primarily designed to be either fully open or fully closed, making it unsuitable for throttling applications. Butterfly valves can be used for throttling, but they are generally less effective in providing fine control over flow, especially at lower flow rates. Ball valves, on the other hand, also provide low resistance to flow when fully open and do not perform well for throttling because they can quickly cause turbulence and are not designed for precise flow regulation. Thus, the globe valve stands out as the preferred choice for applications requiring detailed control over flow.
