What is one of the reasons why globe valves are popular in low-pressure services?

Globe valves are widely favored in low-pressure services primarily due to their effective control of fluid flow. The design of a globe valve allows for significant throttling capabilities, which is essential in applications where precise regulation of flow is required. The internal construction of the globe valve, characterized by a spherical body with a movable plug or disc, enables it to finely adjust the passage of fluid, making it ideal for tasks where maintaining specific flow rates is crucial.

Moreover, the shape of the valve body and the angle at which the fluid enters and exits the valve contribute to its ability to minimize turbulence and pressure loss, leading to an efficient operation in low-pressure systems. While other valves may be designed for different applications, the distinctive capability of globe valves to modulate flow effectively sets them apart in low-pressure scenarios.

Although considerations such as cost and flow rates are important, the primary attribute that aligns with their popularity in these services is their superior control over fluid dynamics.
