Product description
The Monoflange Valve, 3-Valve Manifold, 1/2 in NPT × 2-1/16 in 15M Flanged, 15,000 psi, Sour Service is a small-bore instrumentation valve, 2-1/16 in flange × 1/2 in NPT, 2-1/16 in API 6A 15M Flanged (RTJ) — process side, rated for 15,000 psi. NACE MR0175 / ISO 15156 sour-service compliant.
Monoflange design integrates the primary and secondary isolation valves with a bleed valve into a single flanged body — replaces conventional two-valve plus bleed-valve assemblies on instrumentation tap-offs. Reduces leak paths and weight by 60-70% compared to the equivalent close-coupled assembly.
Construction
- Type: Instrumentation — Monoflange
- Nominal size: 2-1/16 in flange × 1/2 in NPT
- Body material: Forged AISI 4130 — NACE MR0175 compliant
- Stem / trim: 316SS stem + 17-4PH spindle
- Seal / packing: Graphite + Inconel braided packing (sour)
- Inlet: 2-1/16 in API 6A 15M Flanged (RTJ) — process side
- Outlet: 1/2 in NPT Female — instrument side
Performance
Working pressure 15,000 psi. Hydrotested at 1.5× working pressure. Operating temperature -50°F to +250°F (-46°C to +121°C) per the data plate. NACE MR0175 sour-service compliant — material class EE.
Applications
- HPHT pressure-transmitter installation
- 15K wellhead instrumentation
- Christmas-tree gauge tap-offs
- Sour-gas wellhead instrument manifolds
Compliance
- API 6A
- 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) end connections (NPT / integral flanged / autoclave compression), (c) service class (standard vs sour, with H₂S partial pressure data for NACE compliance), (d) handle type (T-bar handle / handwheel / locking lever), (e) any required ATEX / IECEx certifications for hazardous-area mounting. Indus quotes ex-Dubai for stock items and ex-works OEM for build-to-order.
Companion products
Pair with matching flange gaskets and stud bolts per the applicable spec (API 6A 6BX or ASME B16.5). Indus also supplies impulse-line tubing (1/2" / 1/4" / 3/8" 316SS), fittings (compression and weld), and matching mounting brackets on request.
