What is a Globe Valve?
The globe valve gets its name from its shape. It has a body with an interior partition, and the centers of the valve inlet and outlet are aligned. This arrangement causes a change in the flow direction, resembling an S shape.
The flow of fluid is obstructed by the disc or plug as it presses against the seat in the partition.
Globe valves can serve two purposes: controlling the flow rate by adjusting the shape of the disc, and fully opening or closing the flow.
There are three types of flow that can be achieved using a globe valve: straight flow, angle flow, and cross flow.
