Which type of valve allows for smooth flow regulation rather than a simple open/close function?

• A. Ball valve
• B. Globe valve
• C. Gate valve
• D. Check valve

Answer: (B)

The globe valve is designed specifically for flow regulation, making it the correct choice for this question. Its unique construction, which includes a spherical body with a movable disk, allows the valve to be partially open or closed. This feature provides precise control over the flow rate, enabling operators to adjust the flow to the desired levels effectively. The globe valve's design results in a greater pressure drop compared to other valves, but it excels in throttling applications where fine control of flow is necessary. In contrast, other valve types focus primarily on either facilitating or obstructing flow rather than regulating it. For example, the ball valve provides a quick shut-off but does not offer the same level of flow control as the globe valve. The gate valve, much like the ball valve, is generally utilized for on/off service and is not suited for regulating flow. Lastly, the check valve is designed to allow flow in only one direction to prevent backflow, which does not provide any means for flow regulation. Thus, the globe valve stands out as the most appropriate choice for achieving smooth flow regulation.
