What type of valve is generally recommended for throttling applications?

The globe valve is typically recommended for throttling applications due to its design, which allows for precise control over fluid flow. Unlike other types of valves, globe valves have a spherical body shape that creates a tortuous flow path, allowing operators to adjust the opening and thereby control the flow with greater accuracy.

The seating surface of the globe valve, combined with the way the valve stem can be turned to gradually open or close the valve, makes it ideal for throttling, where maintaining a specific flow rate is important. This capability to finely tune flow makes globe valves suitable for regulating pressure and flow in piping systems.

In contrast, ball valves and gate valves are generally used for on/off applications rather than for throttling because their flow paths do not allow for easy adjustments to flow rates. While check valves serve a different purpose by allowing fluid to flow in one direction and preventing backflow, they are not designed for controlling flow rate at all.
