When throttling is required, which type of valve is the proper choice to install?

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

Answer: (C)

The globe valve is the appropriate choice for throttling because it is designed to provide precise control over fluid flow. Its internal structure allows for a variable opening to regulate the flow rate efficiently, which is essential in situations where flow needs to be adjusted or maintained at a specific level. The disk of a globe valve is positioned perpendicular to the flow, allowing for better manipulation of fluid dynamics. In contrast, other types of valves, such as the ball valve, primarily serve as on/off controls and are not designed for fine flow regulation. Similarly, the gate valve is mainly employed for fully opened or closed positions, making it unsuitable for throttling operations. The check valve, on the other hand, prevents backflow and is not used to control flow rates at all. Therefore, the globe valve's design and function make it uniquely suited for tasks requiring throttling, ensuring optimal performance in controlling fluid flow within sewage treatment operations.
