What is the primary function of a globe valve in a system?

The primary function of a globe valve is to regulate flow within a system. Globe valves are designed with a spherical body shape and a movable disk or plug that can precisely control the flow rate and direction of the fluid passing through it. This design allows for fine adjustments to the flow, making globe valves ideal for applications where flow control is critical, such as in heating systems, process piping, and other fluid handling scenarios.

When the valve is partially opened, it enables a controlled amount of fluid to pass, effectively varying the flow rate based on the valve's position. This characteristic distinguishes globe valves from other types of valves that may either be fully open or fully closed without the level of control that globe valves offer. Therefore, the ability to regulate flow makes globe valves an essential component in many engineering systems.
