A globe valve, different from ball 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 with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movable plug can be screwed in to close (or shut) the valve. The plug is also called a disc or disk. In globe valves, the plug is connected to a stem which is operated by screw action using a handwheel in manual valves. Typically, automated globe valves use smooth stems rather than threaded and are opened and closed by an actuator assembly.
Globe valves are devices that are used to control the flow of liquid in a pipeline. They can be used to either stop fluid flow completely, slow it down or allow the fluid to flow freely. Globe valves have a globe-shaped body (hence the name), a flat piece and a ring that the flat piece fit into to stop the fluid flow. Understanding how they work can be really interesting.
Globe valves contain an important device called a baffle. This is the device that is responsible for regulating fluid flow. The baffle consists of two parts, a flat plug and a ring-shaped seat. When the plug is completely fit into the seat, fluid flow is totally restricted. You can control the baffle by either opening it a little or closing it, depending on the amount of fluid flow you want.
Furthermore, there are automatic and manual globe valves. Automatic globe valves lack the threaded stems of the manual ones and they slide smoothly from a closed position to open to regulate the flow of fluid in the pipeline. The mechanical device that is used to operate automatic globe valves is called an actuator.
Globe valves are usually used in applications where constant flow of fluid is not required. Even when the valve is fully open, the baffle can sometimes restrict fluid flow.
