As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance marine valves for critical offshore applications. Our CB/T3191 Marine Ball Valve for FPSO is engineered to meet the rigorous demands of floating production, storage, and offloading units, ensuring reliable flow control in the most challenging marine environments. With every valve undergoing 100% pressure testing and accompanied by a comprehensive Mill Test Report, we provide the quality assurance and documentation that global engineering and procurement teams require for their vital projects.
This valve is designed for superior performance and long-term durability in FPSO systems, where safety and reliability are non-negotiable. The robust construction and meticulous testing protocol make it an ideal choice for various fluid control applications onboard.
- Uncompromised Safety and Reliability: Each valve is subjected to a full pressure test, far exceeding standard sampling checks, to guarantee zero leakage and structural integrity under maximum working pressure. This rigorous process ensures operational safety for critical FPSO systems.
- Full Traceability and Quality Assurance: A detailed Mill Test Report (MTR) is provided with each valve, documenting material chemical composition, mechanical properties, and test results. This traceability is essential for project audits, maintenance records, and compliance with international standards.
- Robust Construction for Harsh Environments: Manufactured from high-grade materials such as carbon steel or stainless steel with superior anti-corrosion treatments, the valve withstands corrosive seawater, high humidity, and variable pressures typical of offshore operations.
- Versatile Configuration Options: Available in a wide range of sizes, pressure classes, and actuation methods (manual, pneumatic, electric) to fit specific pipeline designs and control requirements on FPSO vessels.
- Efficient and Low-Maintenance Design: The quarter-turn operation ensures quick shut-off, while the sealed design and durable seat materials minimize maintenance needs, reducing total cost of ownership over the valve's lifespan.
Technical specifications for standard models are outlined below. Custom configurations are available upon request to meet specific project requirements.

Frequently Asked Questions (FAQ)
Q1: What does "100% Pressure Tested" mean for this valve?
A1: It means every single valve unit, not just a sample from a batch, undergoes a rigorous hydrostatic pressure test. The body is tested to 1.5 times the nominal pressure, and the seat is tested to 1.1 times, ensuring there are no leaks or defects before shipment.
Q2: Why is the Mill Test Report (MTR) important for FPSO applications?
A2: FPSO projects require extensive documentation for quality assurance and regulatory compliance. The MTR provides verifiable proof of the material grade, chemical analysis, and mechanical properties, which is crucial for material traceability, welding procedures, and long-term asset integrity management.
Q3: Is this valve suitable for seawater service?
A3: Yes. The valve can be manufactured using corrosion-resistant materials like stainless steel (CF8/CF8M) and with appropriate surface treatments to handle seawater, ballast water, and other corrosive media commonly found in marine and FPSO environments.
Q4: Can you provide valves with actuators?
A4: Certainly. We offer a range of actuation solutions including manual gear operators, pneumatic actuators, and electric actuators. The specific type can be selected based on your control system requirements and available power source onboard.
Q5: What is the typical delivery lead time for an order?
A5: Lead time depends on the order quantity, size, and material specifications. Standard configurations typically have shorter lead times. We recommend contacting our sales team with your specific requirements for an accurate production and delivery schedule.
Q6: Do your valves comply with other international standards besides CB/T3191?
A6: While CB/T3191 is the primary design standard for marine applications, our manufacturing process and quality control are governed by our ISO9001 system. Valves can be produced to meet other recognized standards such as API, ASME, or DIN based on customer request.
Q7: What kind of packaging do you use for export to ensure valve protection?
A7: We use robust export-standard packaging. Valves are typically cleaned, dried, coated with anti-rust preservative, and sealed with end caps. They are then packed in wooden cases or crates suitable for long-distance ocean freight and harsh handling conditions.
Q8: What after-sales support do you provide?
A8: We provide technical documentation, installation guidance, and responsive support for any operational inquiries. While specific warranty terms depend on the application, we are committed to ensuring customer satisfaction with our products and services.
