Forged Globe Valves Supplier & Manufacturer

What Is a Forged Globe Valve?

A globe valve takes its name from the rounded shape of its body. Inside that body sits a disc that lowers onto, or lifts clear of, a fixed seat as you turn the handwheel, which lets you set the flow anywhere between fully open and fully closed rather than just switching it on or off. Most globe valves spend their working life fully open or fully closed, but because the disc position can be fine-tuned, they also handle light throttling duty well, which is exactly why they’re a common choice for steam and gas lines where flow needs occasional adjustment.

Straight-Through, Angle and Oblique Patterns

Forged globe valves come in three body patterns. A straight-through pattern is the standard choice for most lines. An angle pattern turns the flow 90 degrees, which is worth considering for our angle type globe valves range when the piping layout already needs a turn at that point. An oblique pattern angles the internal flow path to increase the flow coefficient and cut pressure drop compared to a standard straight-through design, useful where every bit of pressure recovery matters.

Installation Note

Globe valves need to be installed the right way round: flow should pass from underneath the disc upward through the seat. Getting this backwards increases wear on the disc and seat and can affect shut-off tightness, so it’s worth checking the flow arrow on the body before welding or bolting the valve into the line.

Where Forged Beats Cast

Forging suits small-bore, high-pressure duty because a forged body can hit a very high pressure class without needing the extra wall thickness a cast body of the same size would require. That’s why our forged globe valve range tops out around 2 inches, handing off to cast steel globe valves for larger sizes where casting becomes the more economical route.

The body material you pick is really a shortcut to the right grade family:

• A105 is our standard forged carbon steel body for general and ambient service
• LF2 is the low-temperature version, matching our LTCS A350 LF2 fittings for a consistent cold-service hook-up
• F5, F9, F11 and F22 are alloy steel grades for elevated-temperature service
• F304, F316, F316L, F321 and F347 are the forged equivalents of stainless steel for corrosion resistance
• F51 and F55 step up to duplex and super duplex steel for high-chloride and sour service
• Inconel, Monel, Hastelloy and Alloy 20 cover the toughest, most corrosive services; see our Inconel, Monel, Hastelloy and Alloy 20 ranges
