Product description
The Hydraulic Gate Valve, Fail Close, 4-1/16 in × 5M Flanged, 5,000 psi, API 6A PSL 3 PR2, EE-0.5 is rated for 5,000 psi working pressure (5K class) per API 6A PSL 3, PR2, material class EE-0.5. Hydraulically-actuated, fail-close (spring closes on hydraulic loss) — required for downstream isolation and safety integrity. Manual override on the bonnet for testing and lockout.
Construction
- Type: Gate — Hydraulic — Fail Close
- Nominal size: 4-1/16 in
- Bore: Full Port
- Body material: Forged AISI 4130 — NACE MR0175 compliant
- Trim material: F6NM gate + Inconel 625 overlay seats
- Seal / elastomer: PEEK back-up + HNBR primary seals
- Inlet: 4-1/16 in API 6A 5M Flanged (RTJ)
- Outlet: 4-1/16 in API 6A 5M Flanged (RTJ)
- Actuator: hydraulic dome — control pressure typically 1.5× working pressure
Performance
Working pressure 5,000 psi. Bidirectional flow with metal-to-metal seat seal. Hydrotested at 1.5× working pressure (shell test) and seat-tested per API 6A acceptance criteria. NACE MR0175 / ISO 15156 sour-service compliant — H₂S-rated trim and elastomers.
Applications
- High-rate 5K production trees
- Large-bore master valve service
- Multi-phase production headers
- Sour-gas processing inlet manifolds
Compliance
- API 6A PSL 3 PR2
- Material class EE-0.5 (API 6A chemistry / sour-service grading)
- NACE MR0175 / ISO 15156 (sour-service)
- Mill test reports per EN 10204 3.1 / 3.2
- API monogram traceability on body and trim
How to order
Confirm (a) line working pressure and pressure class, (b) inlet and outlet end-connection sizes / styles (5M / 10M / 15M flanges, or other), (c) service class (standard vs sour vs HF), (d) actuator mode for hydraulic variants (FC, FLS, or manual override option), (e) any special trim (Inconel 625, Stellite, F22) or temperature class (PR1 / PR2 / PR2F fire-tested) requirements. Indus quotes ex-works with full mill test reports, sour-service certificates where applicable, and pre-shipment hydrostatic / shell test certificates.
Companion products
Pair with matched-pressure check valves, ball valves, and SSV/ESDs of the same flange class to build a complete wellhead service tree or Christmas tree. For hydraulic-actuated trains, integrate with a hydraulic control panel sized to the dome volumes and intervention timings. Indus also supplies API 6A studs, gaskets (R/RX/BX ring-joint), and instrumentation tap-offs to specification.
