What is a Globe Valve?
The globe valve gets its name from its shape. It has a body with an interior partition, and the centers of the valve inlet and outlet are aligned. This arrangement causes a change in the flow direction, resembling an S shape.
The flow of fluid is obstructed by the disc or plug as it presses against the seat in the partition.
Globe valves can serve two purposes: controlling the flow rate by adjusting the shape of the disc, and fully opening or closing the flow.
There are three types of flow that can be achieved using a globe valve: straight flow, angle flow, and cross flow.
Parts of a Globe Valve
|
Angle Body |
used in intersecting lines. |
|
Welded Bonnet |
Generally used for gas and toxic flow line applications. |
|
Outside Screw & Yolk |
An outside screw and yoke type design is generally used for all globe valves. |
|
Pressure Seal |
On a pressure-seal valve, the higher the body cavity pressure, the greater the force on the gasket. Pressure-seal bonnets are used extensively for high- pressure high-temperature applications, such as the power industry. Pressure-seal valves are much lighter than bolted bonnet designs. Due to the pressure energization of the seal ring, they are normally not used in pressure classes below ANSI class 600. |
|
Extended Stem |
Stem extended at bonnet for cryogenic, pressure-seal, and buried (Under Ground) applications. |
|
Ball Type Disc |
Globe valves feature a ball-type disc that provides a fine-grain surface on the taper seat. |
|
Plug Type Disc |
For services that demand hard-faced seats, a plug-type disc is provided. Also known as a Swivel Plug Disc. |
|
Renewable Seat |
These seats can be replaced easily if required. They will often be threaded seats or freely placed seats. |
|
Integral Seat |
Machined in the body or welded to the body. Cannot be replaced easily. |
