Surface Safety Valve, Hydraulic, 3-1/16 in × 10M Flanged Inlet × 3 in 1502 F×M Outlet, 10,000 psi, API 6A PSL 3 PR1, EE-1.5

The Surface Safety Valve, Hydraulic, 3-1/16 in × 10M Flanged Inlet × 3 in 1502 F×M Outlet, 10,000 psi, API 6A PSL 3 PR1, EE-1.5 is rated for 10,000 psi working pressure (10K class) per API 6A PSL 3, PR1, material class EE-1.5. Hydraulically-actuated fail-close emergency shutdown valve — closes on loss of hydraulic control pressure to the actuator dome. SSV Class II per API 6A (block-bleed-blow).

Construction

• Type: Surface Safety (SSV)
• Nominal size: 3-1/16 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: 3-1/16 in API 6A 10M Flanged (RTJ)
• Outlet: 3 in 1502 F×M Weco Union
• Actuator: hydraulic dome — control pressure typically 1.5× working pressure

Performance

Working pressure 10,000 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

• Frac iron emergency shutdown
• Tree-to-flow-iron adapter point
• Coiled-tubing intervention safety
• 10K well-test surface trees

Compliance

• API 6A PSL 3 PR1
• Material class EE-1.5 (API 6A chemistry / sour-service grading)
• NACE MR0175 / ISO 15156 (sour-service)
• SSV Class II — block-bleed-blow per API 6A
• 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 full-stack emergency shutdown, pair the SSV with an upstream wing/master valve and downstream bleed/check sequence. Indus also supplies API 6A studs, gaskets (R/RX/BX ring-joint), and instrumentation tap-offs to specification.
