Globe Valve, 2 in × 300# RF, 740 psi, Sour Service

The Globe Valve, 2 in × 300# RF, 740 psi, Sour Service is a process globe valve rated for 740 psi working pressure (ANSI 300 class), 2 in 300# ANSI Raised-Face Flange. NACE MR0175 / ISO 15156 sour-service compliant.

Linear-motion plug-on-seat design — the disc translates vertically against a circular seat. Suitable for both fully open / fully closed isolation AND throttling service (unlike ball / gate / plug valves which are isolation-only). Closure tightness is set by the seat and disc machining; throttling capability comes from the body's tortuous flow path which gives a near-linear flow coefficient curve.

Construction

• Type: Globe — NACE-Compliant ANSI 300
• Nominal size: 2 in
• Body material: Cast WCB carbon steel — NACE MR0175 compliant
• Trim (disc + seat + stem): 410SS trim with Stellite 6 hardfacing — NACE compliant
• Seal / packing: Graphite + Inconel braided packing (sour)
• Inlet: 2 in 300# ANSI Raised-Face Flange
• Outlet: 2 in 300# ANSI Raised-Face Flange

Performance

Working pressure 740 psi. Hydrotested at 1.5× working pressure (shell test) and seat-tested per API 6D acceptance criteria. NACE MR0175 / ISO 15156 sour-service compliant — material class EE.

Applications

• Sour-gas processing inlet utility
• Acid-gas treatment manifolds
• Sour-water stripper feed lines
• Refinery sour-service isolation

Compliance

• API 6D / ASME B16.34
• NACE MR0175 / ISO 15156 (sour-service)
• Mill test reports per EN 10204 3.1 / 3.2

How to order

Confirm (a) line working pressure and pressure class, (b) flange class and gasket style (ANSI raised-face = the default; ring-joint flanges available on request), (c) service class (standard vs sour), (d) operation preference (rising-stem handwheel default; gear-reduction handwheel available for sizes ≥ 4-inch), (e) for throttling service, the desired flow coefficient (Cv) — Indus can match the trim characterisation curve. Quoted ex-works OEM with full mill test reports.

Companion products

Pair with matched-pressure check valves and isolation valves of the same flange class. For throttling-control service, also specify the matching positioner and instrument-air panel. For sour gas processing, the EE-class chemistry trim is standard; HH-class is available for severe sour environments.
