What is a globe valve?
Initially characterized by their spherically shaped valve bodies, globe valves use a moveable plug or disc to control flow between the two separate chambers in the valve body. The disc moves in a linear direction as its actuator rotates the stem lifting or lowering the plug or disc. This either allows flow, modulates the flow, or stops the flow through the orifice.

How a globe valve works?
The exterior structure of a globe valve includes a valve body, handwheel, and bonnet. A threaded valve stem or screw connects to the handwheel and penetrates into the bonnet. On the interior end of the valve stem is a disc or plug, which can be a variety of shapes, depending on the application.
There are five main components in a globe valve: valve body, bonnet, handwheel, stem, and plug. Media flows into the valve body through an inlet and exits the valve body through an outlet. The bonnet protects the threaded components of the valve and attaches to the valve body.
