• Globe valves are typically two-port valves, although three port valves are also produced mostly in straight-flow configuration. Ports are openings in the body for fluid flowing in or out. The two ports may be oriented straight across from each other or anywhere on the body, or oriented at an angle (such as a 90°). Globe valves with ports at such an angle are called angle globe valves. Globe valves are mainly used for corrosive or high viscous fluids which solidify at room temperature. This is because straight valves are designed so that the outlet pipe is in line with the inlet pipe and the fluid has a good chance of staying there in the case of horizontal piping. In the case of angle valves, the outlet pipe is directed towards the bottom. This allows the fluid to drain off. In turn, this prevents clogging and/or corrosion of the valve components over a period of time. A globe valve can also have a body in the shape of a "Y". This will allow the construction of the valve to be straight at the bottom as opposed to the conventional pot type construction (to arrange bottom seat) in case of other valves. This will again allow the fluid to pass through without difficulty and minimizes fluid clogging/corrosion in the long term.

Globe Valve Application
Globe valves are primarily used as control valves where throttling or both throttling and shut-off are required. Globe Valves can also be used for on-off service; however, because of design, a pressure drop becomes inherent. This is generally confined to on-off applications where the valve is normally closed and pressure drop is not important when the valve is open. Globe valves are uni-directional valves and normal applications will find the globe valve with the flow and pressure under the disc. GLT cast steel globe valves are commonly made in outside screw and yoke designs with full ports and heavy-duty type discs.
Disc
The valve is normally supplied with the conical plug type disc. The disc rotates freely on the stem and incorporates a differential angle from that on the seat ring. This design provides the maximum assurance of shut off, is less likely to stick in the body seat, and is considered the simplest design for field repair.
Stem
All stem are rotating, rising and designed with integral backseat features which provide an ultimate seal during packing changes.
Packing
The stem packing is designed and arranged to ensure a maximum seal along the stem during operation or while at position, thus allowing for a greater reduction in fugitive emissions. Our packings are made of Graphite(Non-asbestos).
End Connections
Our standard end connection produce valves with:
- Flange end type with Raised Face(RF), Flat Face(FF) or Ring Type Joint(RTJ) that conform to ANSI B16.5.
- Butt-welding ends(BW) that conform to ANSI B16.25.
- Threaded ends(NPT) that conform to ANSI B1.20.1, socket weld ends that conform to NASI B16.11.
- All face to face /end to end dimensions conform to ANSI B16.10
Other special end connections are supplied according to customer's requirements.
