Which valve is known to have more restriction than a gate valve and can be used to throttle flow?

The globe valve is specifically designed to provide higher resistance to flow than a gate valve, making it suitable for throttling applications. Its internal structure features a movable disk that can be positioned to adjust the flow rate, allowing for precise control. This design contrasts with that of a gate valve, which is generally intended for fully open or fully closed operations and is not effective for regulating flow.

In throttling applications, the globe valve's ability to create a greater pressure drop by restricting flow more effectively than other valve types is crucial. This characteristic is beneficial in systems where flow needs to be controlled finely, such as in heating and cooling systems or in various industrial processes.

While other valves, such as butterfly, check, and ball valves, can be used in different flow scenarios, they do not provide the same level of throttling capability as the globe valve. Butterfly valves are better suited for regulating large volumes of flow, check valves are designed to prevent backflow without controlling system pressure, and ball valves are typically used for on-off control with minimal flow resistance due to their design. Thus, the globe valve stands out as the best option for applications requiring flow regulation and throttling.
