The globe valve is named after its shape. Its body has an interior partition, and the valve inlet and outlet centers are inline. This configuration forces a change in the direction of flow in the form of an S. A Globe valve is a device 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 have a 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 in manual valves. Typically, automated valves use sliding stems. Automated globe valves have a smooth stem rather than threaded and are opened and closed by an actuator assembly. When a globe valve is manually operated, the stem is turned by a hand wheel.http://www.didlink-valve.com/

Generally speaking, there are 3 styles of globe valves: straight pattern, angle pattern and Y-pattern. These are determined by the geometry of the end connection and the stem. In a straight pattern globe, the end connections for a straight line with the stem pointing vertically from this line. A Y-pattern is similar but the stem is angled by 45 degrees from the inlet-outlet path. An angle valve has the inlet and outlet oriented 90 degrees from each other with the stem perpendicular from one and in line with the other. Typically globe valves are made of metallic alloys, although some synthetic materials are available. These materials are chosen based on pressure, temperature, and controlled media properties. Corrosive and/or erosive process streams may require a compromise in material selection or exotic alloys or body coatings to minimize these material interactions and extend the life of the valve or valve trim components. Typically, carbon steel alloys are specified for no corrosive applications. Other alloys such as Hastelloy, Monel, Inconel and others are available.
