Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016 and certified to ISO9001 quality management standards, is a professional manufacturer dedicated to providing robust and reliable fluid control solutions for demanding industrial applications. We proudly introduce our specialized FPSO Service Ball Valve, a product engineered to meet the rigorous challenges of offshore oil and gas production. Designed in strict compliance with the CB/T3191 standard, this forged steel, 2-piece ball valve offers exceptional performance, durability, and safety for critical service on Floating Production, Storage, and Offloading (FPSO) vessels, where failure is not an option. Our commitment to precision manufacturing and stringent quality control ensures that every valve delivers the dependable operation required in harsh marine environments.
This valve is specifically engineered for the unique demands of offshore service, combining robust construction with reliable sealing technology. Its core value lies in providing a long-lasting, maintenance-friendly, and safe isolation solution for various process and utility lines on FPSO units, including crude oil, produced water, gas, and chemical injection systems. By choosing our FPSO Service Ball Valve, you invest in operational integrity, reduced downtime, and enhanced safety for your offshore assets.
Detailed Product Features & Technical Specifications:
Our FPSO Service Ball Valve is built with a focus on durability, ease of operation, and compliance with marine standards. Below are its key characteristics and advantages:
- Robust Forged Steel Construction: The valve body and ball are forged from high-grade materials such as A105 carbon steel or ASTM A182 F304/F316 stainless steel. Forging provides superior mechanical strength, better grain structure, and higher resistance to impact and pressure fatigue compared to cast equivalents, making it ideal for the dynamic loads and corrosive atmosphere of offshore platforms.
- 2-Piece Bolted Body Design: This design offers excellent structural integrity and simplifies maintenance. The body sections are joined with high-strength bolts, allowing for easier in-line inspection, seat replacement, or repair without fully removing the valve from the pipeline, significantly reducing maintenance time and costs.
- CB/T3191 Compliance: Manufactured in accordance with the Chinese ship standard CB/T3191, which specifies requirements for marine valves. This ensures the valve meets recognized criteria for design, materials, pressure-temperature ratings, and testing, providing assurance of its suitability for marine applications.
- Reliable Sealing System: Features advanced seat materials like PTFE or reinforced PTFE for standard services, providing excellent sealing and low operating torque. For more severe services, metal-seated or fire-safe designs (API 607/API 6FA compliant, available upon request) can be provided to ensure bubble-tight shut-off and safety in emergency situations.
- Versatile Pressure Ratings: Available in pressure classes PN10 and PN16 (corresponding to ANSI Class 150 and 300), offering flexibility for different system pressure requirements on an FPSO.
- Multiple Actuation Options: The valve can be supplied with a standard lever for manual operation, or equipped with gear operators, pneumatic actuators, or electric actuators for remote and automated control, facilitating integration into the vessel's control systems.
- Anti-Static and Blowout-Proof Stem: The stem design incorporates features to prevent static electricity buildup and ensure it is retained under pressure, enhancing operational safety.
- Full Port or Reduced Port: Available in full bore design to minimize pressure drop and allow for pipeline pigging, or standard port for general service applications.

- Operational Flexibility: With multiple pressure ratings, end connections, and actuation options, the valve can be customized to fit specific system layouts and functional requirements on your FPSO.
- Global Supply Chain Support: With an annual export value between US$1 Million and US$1.5 Million and major shipment ports in Shanghai, Guangzhou, Hong Kong, and Beijing, we efficiently serve a global clientele across North America, South America, Europe, Asia, Africa, and Oceania.
Frequently Asked Questions (FAQ):
Q1: What does "CB/T3191 compliant" mean for my FPSO application?
A1: CB/T3191 is a Chinese national standard for marine valves. Compliance indicates the valve is designed, manufactured, and tested to meet specific requirements for marine use, including material selection, pressure ratings, and structural integrity, ensuring its suitability and reliability in offshore environments like FPSOs.
Q2: Why choose a forged steel valve over a cast steel valve for FPSO service?
A2: Forged steel offers superior mechanical properties, including higher strength, better impact resistance, and a more homogeneous structure with fewer inherent defects. This makes it more reliable for handling the high pressures, thermal cycling, and potential shock loads encountered on offshore platforms.
Q3: Can this valve be supplied with fire-safe certification?
A3: Yes. We offer fire-safe versions of this valve that can be designed and tested in accordance with standards like API 607 or API 6FA. This is a crucial option for hydrocarbon services where valve integrity during a fire is essential. Please specify this requirement when inquiring.
Q4: What are the available actuation methods?
A4: The valve is versatile and can be operated manually via a lever or gearbox. For automated control, it can be fitted with pneumatic (double-acting or spring-return) or electric actuators. The choice depends on your system's control philosophy and available utilities.
Q5: What is the typical lead time for an order?
A5: Lead time varies based on order quantity, material specification, and actuation requirements. Standard configurations typically have shorter lead times. We provide accurate delivery schedules upon receipt of your detailed specifications.
Q6: Do you provide technical support and documentation?
A6> Absolutely. As a manufacturer, we provide comprehensive technical data sheets, material certificates, and, when applicable, test reports. Our engineering team is available to offer support for valve selection, installation, and application-specific queries.
Q7: Are other pressure ratings like PN25 or ANSI Class 600 available?
A7: The standard offering covers PN10 and PN16. However, we have the capability to manufacture valves for higher pressure classes. Please contact us with your specific pressure rating requirement for a customized solution.
Q8: How do you ensure quality control?
A8> Our manufacturing process is governed by an ISO9001 certified quality management system. Each valve undergoes rigorous inspections and tests, including material verification, pressure testing, and functional checks, to ensure it meets all specified requirements before shipment.
Backed by nearly a decade of manufacturing expertise and a proven track record of supplying valves to a diverse range of international markets, Shanghai Zhibang Valve is a partner you can trust for your critical offshore needs.
