Globe Valve, 1 in × 1500# RF, 3,705 psi, Sour Service

The Globe Valve, 1 in × 1500# RF, 3,705 psi, Sour Service is a process globe valve rated for 3,705 psi working pressure (ANSI 1500 class), 1 in 1500# 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 1500
• Nominal size: 1 in
• Body material: Forged AISI 4130 — NACE MR0175 compliant
• Trim (disc + seat + stem): F6NM trim with Inconel 625 overlay seats — NACE compliant
• Seal / packing: Graphite + Inconel braided packing (sour)
• Inlet: 1 in 1500# ANSI Raised-Face Flange
• Outlet: 1 in 1500# ANSI Raised-Face Flange

Performance

Working pressure 3,705 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

• HPHT analyser tap-offs (sour)
• Sample-line throttling (sour)
• 1500# class instrumentation isolation
• Sour-gas leak-test 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.
