Globe valves are primarily used for what purpose?

Globe valves are primarily designed for throttling fluid flow, which involves the regulation and control of flow rate through a piping system. This type of valve has an internal baffle that provides good flow characteristics and allows for precise adjustment, making it ideal for applications where flow needs to be finely controlled.

When a globe valve is partially opened or closed, it can effectively manage the volume of fluid passing through it, unlike other types of valves that are often designed for more straightforward on-off control. The design of the globe valve enables a greater degree of control during operation, allowing for changes in flow rate without significantly affecting system pressure. This feature makes it particularly suitable for situations where maintaining specific flow conditions is critical, such as in heating, cooling, and process control applications.

Understanding that the globe valve excels in throttling fluid flow is essential for power engineers, as it directly impacts system efficiency and operational performance.
