What is a Globe Valve?
A Globe Valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body. Globe valves are named for their spherical body shape. They are designed for throttling and frequent operation. Unlike gate valves, globe valves can be used to regulate flow and are much more efficient at sealing than gate valves, though they do cause a higher pressure drop.
Working Principle
The globe valve works by the movement of a disc vertically relative to the seat. The stem moves the disc up or down to open or close the flow. The fluid follows an S-shaped path through the valve body, which is what allows for precise throttling. As the disc is moved closer to the seat, the annular space through which the fluid passes is reduced, allowing for accurate control over the flow rate. Our globe valves are designed to provide a bubble-tight shut-off and reliable regulation.
