In what scenario is a globe valve preferably used?

• A. For cutting off flow completely
• B. For fine adjustments to flow control
• C. For one-directional flow only
• D. For high-pressure systems

Answer: (B)

A globe valve is primarily designed for flow control, allowing for fine adjustments in the flow rate of the fluid passing through it. The internal design of the globe valve, featuring a movable disk and a stationary ring seat, enables precise regulation of flow, making it the ideal choice for situations where adjustments to the flow need to be made. In contrast, while a globe valve can indeed shut off flow completely, this is not its primary function and there are other valve types, such as gate valves, that perform this role more effectively. The design and mechanics of a globe valve do not lend themselves to supporting one-directional flow exclusively, which is typically managed by check valves. Furthermore, globe valves are versatile in application and may not be the best choice for high-pressure systems compared to other valves specifically engineered for handling high pressures efficiently.
