Globe Valves

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 diskin globe valves, the plug is connected to a stem which is operated by screw action using a hand wheel in manual valves.

Globe valves are commonly used as an on/off valve, but they may be used for throttling systems. The gradual change in spacing between the disk and seat ring gives the globe valve good throttling ability. These linear motion valves can be used in a variety of applications as long as the pressure and temperature limits are not exceeded, and the process does not require special materials to combat corrosion. Globe valve also have a smaller chance of damage to the seat or valve plug by the fluid, even if the seat is in the partially open position.

Globe valves can be used in systems that require frequent stroking, vacuum, and systems that have a wide range of temperature extremes.
