High-Pressure Marine Ball Valve CB/T3191 for FPSO, Fire-Safe API607 Design, PN16MPa
Product Spotlights
As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co.,ltd is dedicated to providing high-performance, reliable fluid control solutions for demanding offshore and marine applications. Our High-Pressure Marine Ball Valve, engineered to CB/T3191 standards and featuring a fire-safe design compliant with API607, is a critical component for ensuring safety and operational integrity on Floating Production Storage and Offloading (FPSO) units. This valve combines robust construction with advanced safety features, offering a dependable sealing solution under extreme pressures up to PN16MPa, making it an ideal choice for critical service lines where failure is not an option.
Product Features & Technical Advantages:
- Fire-Safe API607 Certification: The valve is designed with a primary soft seat and a secondary metal-to-metal seat. In the event of a fire, the primary seat may be compromised, but the secondary metal seat ensures continued sealing integrity, preventing catastrophic fluid release. This is a non-negotiable safety requirement for hydrocarbon processing areas on FPSOs.
- High-Pressure Resilience (PN16MPa): Engineered for high-pressure service, the valve body, ball, and stem are constructed from high-grade materials to withstand the intense stresses of PN16MPa (2320 psi) operating pressure, ensuring long-term performance without leakage.
- Marine-Grade Corrosion Protection: Recognizing the harsh offshore environment, the valve features enhanced surface treatments and material selections (such as optional stainless steel) to resist saltwater corrosion, extending service life and reducing maintenance frequency.
- Robust CB/T3191 Compliance: Manufactured in strict accordance with the Chinese shipbuilding standard CB/T3191, this valve meets the specific dimensional, material, and testing requirements for marine piping systems, ensuring compatibility and reliability in shipboard installations.
- Versatile Actuation Options: Available with manual lever operation, gearbox for high-torque applications, or automated pneumatic actuation for remote control integration into the vessel's control system, enhancing operational flexibility.
- Bidirectional Sealing: The precision-machined ball and seat assembly provides excellent bidirectional sealing (both upstream and downstream), suitable for applications where flow direction may change.
- Low Torque Operation: Despite its high-pressure rating, the valve is designed for smooth, low-torque operation, reducing operator effort and wear on actuation components.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of the API607 fire-safe design in this ball valve?
A: The primary advantage is enhanced safety during a fire event. The design incorporates a secondary metal seal that engages if the primary soft seal is destroyed by fire, maintaining valve closure and preventing the escalation of a fire by blocking fuel supply, which is crucial for FPSO hydrocarbon systems. -
Q: Can this valve be used for services other than on FPSOs?
A: Absolutely. While optimized for FPSO applications, this valve is suitable for any high-pressure, fire-safe critical service in the marine and offshore industry, including platforms, tankers, LNG carriers, and onshore oil & gas terminals requiring API607 compliance. -
Q: Are different end connection types available besides flanged?
A: Yes. While flanged connections are standard per CB/T3191, we can provide valves with butt weld ends (BWE) for permanent, high-integrity piping connections upon request. Socket weld ends may also be available for smaller sizes. -
Q: What materials are recommended for seawater service on an FPSO?
A: For seawater or highly corrosive services, we recommend selecting a valve with a body and internal wetted parts made from austenitic stainless steel (e.g., CF8M/SS316) to ensure superior corrosion resistance and longevity. -
Q: Is the valve suitable for both on/off service and throttling?
A: This ball valve is primarily designed for reliable isolation (on/off service). While it can be used for moderate throttling, prolonged throttling may accelerate wear on the seat, especially with abrasive media. For frequent throttling, a different valve type might be suggested. -
Q: Do you provide actuated versions for automated control systems?
A: Yes. We can equip the valve with pneumatic (single or double-acting) or electric actuators. Please provide your required torque, supply pressure, or voltage specifications for a precise quote. -
Q: What documentation accompanies the valve upon delivery?
A> Standard documentation includes a Material Test Certificate (MTC), product manual, and a Certificate of Conformance. Third-party inspection reports, fire test certificates (for API607), and NDE reports (like PMI) can be provided as optional extras. -
Q: What is your typical lead time for an order of DN100 valves?
A> Lead times vary based on order quantity, material selection, and actuation requirements. For standard carbon steel, flanged, manual lever valves in common sizes, production lead time is typically 4-6 weeks. We provide accurate timelines upon receipt of your specific inquiry.
