Globe valves have been found to offer unparalleled performance when compared to other valves in the flow control industry.
This article covers everything you need to know about globe valves, including their types, components, and how they work. We also provide tips for selecting the ideal globe valve based on factors such as material, size and pressure limitations.
What is a Globe Valve?
A globe valve is a valve used to start, stop or regulate flow in a pipeline. The valve has a movable disc element in the body and a fixed ring seat to throttle effectively and allow precise control.
Although a globe valve can be used as a blocking or isolation valve, it is designed to regulate flow in a partially open position, while a gate valve is designed to be used in a fully open or fully closed position. When considering the use of a globe valve for on-off isolation service valves, the design should be chosen carefully, as it is difficult to maintain a tight seal under the force of the push on the disc. When the flow comes from the direction above the disc, the force of the fluid helps to achieve a positive seal and is easier to achieve.
The regulating function of the globe valve makes it ideal for control valve applications, where positioners and actuators attached to the globe valve cover and stem enable very precise regulation.
Working Principle
Performance specification
The globe valve can handle a temperature range from -425 °F to 1100°F, depending on the construction of the globe valve. Valves range in size from 5 inches to 48 inches (DN6 to 1200), and manual globe valves can weigh up to 13,000 pounds. When selecting a valve, the given and desired properties of the flow can be used.
