A high quality globe valve is a linear motion valve and is primarily designed to stop, start and regulate flow. The disk of a Globe valve can be totally removed from the flow path or it can completely close the flow path. 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. In globe valves, the plug is connected to a stem which is operated by screw action using a handwheel in manual valves. The globe valve plug type disc must be installed in proper relation to the media flow as indicated by the flow direction arrow on the valve body.
The principal variation in Globe-valve design is in the types of discs employed. Plug-type discs have a long, tapered configuration with a wide bearing surface. This type of seat provides maximum resistance to the erosive action of the fluid stream. In the composition disc, the disc has a flat face that is pressed against the seat opening like a cap. This type of seat arrangement is not as suitable for high differential pressure throttling.
Maintenance of Globe valves is relatively easy, as the discs and seats are readily refurbished or replaced. This makes Globe valves particularly suitable for services that require frequent valve maintenance. Where valves are operated manually, the shorter disc travel offers advantages in saving operator time, especially if the valves are adjusted frequently.
Advantages Of Globe Valves
Good shutoff capability.
Moderate to good throttling capability.
Shorter stem travel between the open and closed positions as compared to a gate valve.
Available in many patterns, each offering unique capabilities.
Easy maintenance, as the discs and seats are readily refurbished or replaced.
Globe Valve Body Patterns
There are three primary body patterns or designs for Globe valves, namely:
Standard Pattern (also known as T Pattern or Z Pattern)
Angle Pattern
Oblique Pattern (also known as Y Pattern)
