As a specialized manufacturer with a strong presence in the global industrial valve market, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly introduces our engineered Corrosion Resistant FPSO Butterfly Valve with Fire-Safe Design API 609. Designed for the demanding environments of Floating Production Storage and Offloading units, this valve represents the culmination of precision engineering, stringent material selection, and adherence to the highest international standards. Our focus on reliability and safety ensures that our valves provide a robust sealing solution for critical hydrocarbon processing, transfer, and storage applications offshore.
Established in 2016, we have built a reputation for delivering high-performance fluid control solutions. Our commitment is reflected in our ISO9001-certified quality management system and our products reaching diverse markets across North America, South America, Europe, Asia, Africa, and Oceania. This specific valve is engineered to address the unique challenges of marine and offshore operations, where corrosion resistance and fire integrity are non-negotiable for asset protection and personnel safety.
Core Product Features & Technical Advantages:
Our FPSO Butterfly Valve is not a standard industrial valve; it is a purpose-built component for one of the most challenging applications. Its design philosophy centers on three pillars: Uncompromising Safety, Superior Durability, and Operational Efficiency.
- API 609 Fire-Safe Design: In the event of a fire, the valve is engineered to maintain a pressure seal. The design incorporates a secondary metal-to-metal sealing mechanism that engages if the primary soft seat is compromised by heat, helping to prevent the escalation of an incident.
-
Enhanced Corrosion Protection: FPSO environments expose equipment to saltwater spray, humidity, and corrosive process fluids. We combat this through:
- Body & Disc: Carbon steel with high-performance epoxy or FBE coating, 316/316L stainless steel, Duplex (2205) or Super Duplex stainless steels for superior chloride resistance.
- Seat: PTFE or reinforced PTFE for excellent sealing and chemical resistance; Perfluoroelastomer (FFKM) options for aggressive chemicals; Fire-safe metal secondary seat.
- Stem: Stainless steel 316, 17-4PH, or Monel for high strength and corrosion resistance.
- Extended Service Life & Reduced OPEX: Superior corrosion protection directly translates to fewer replacements, lower maintenance frequency, and reduced lifecycle costs.
- Enhanced Safety Compliance: The API 609 fire-safe certification provides documented evidence for safety case submissions and helps meet stringent regulatory requirements.
- Reliable Performance: Precision machining ensures bubble-tight shut-off and smooth, low-torque operation, even after long periods in the open or closed position.
- Global Supply Chain Support: With annual export values between US$1-1.5 million and major shipment ports in Shanghai, Guangzhou, Hong Kong, and Beijing, we ensure reliable and timely delivery to projects worldwide.

Frequently Asked Questions (FAQ):
Q1: What exactly does "API 609 Fire-Safe" mean for this butterfly valve?
A1: API 609 is a standard that specifies fire-testing requirements for soft-seated, quarter-turn valves. A "Fire-Safe" designation means the valve has been tested to maintain a seal under specified fire conditions. Our valve incorporates a design where, if the primary soft seat (e.g., PTFE) is damaged by fire, a secondary metal sealing surface engages to provide continued sealing capability, helping to contain the fluid and prevent feeding a fire.
Q2: Can this valve be used in submerged or constantly wet offshore conditions?
A2: Yes, its corrosion-resistant design is specifically intended for such harsh environments. However, the specific material grade (e.g., Duplex stainless steel vs. coated carbon steel) must be selected based on the exact service fluid (e.g., seawater, brackish water) and immersion conditions. We provide guidance on material selection to ensure long-term integrity.
Q3: What types of actuators are compatible with this valve?
A3: The valve is designed with a standardized mounting pad according to ISO 5211, making it compatible with a wide range of quarter-turn actuators. We can supply the valve as a manual unit (lever or gear operated) or as a complete package with electric, pneumatic, or hydraulic actuators from reputable brands, tailored to your control system requirements.
Q4: Is the fire-safe testing performed by a third party, and is certification provided?
A4: Fire-safe testing is typically conducted by independent, accredited laboratories. While our standard offering is designed to meet API 609 requirements, specific certified test reports for a particular valve size and material combination are available upon request and may involve additional lead time and cost.
Q5: What is the typical delivery lead time for an order?
A5: Lead time depends on the order quantity, material specifications, and actuation requirements. Standard configurations in common sizes may have shorter lead times. We utilize multiple ports (Shanghai, Guangzhou, Hong Kong, Beijing) to optimize shipping logistics. A precise delivery schedule will be provided with your formal quotation.
Q6: Do you offer custom coatings or cathodic protection connections?
A6: Yes, customization is a key strength. We can apply specialized coatings like glass flake, zinc aluminum, or others as per project specifications. The valve body can also be furnished with standard cathodic protection (CP) test points or connections for integration into the FPSO's CP system, which is crucial for submerged or splash zone applications.
Q7: How does this valve compare to a gate valve for FPSO applications?
A7: Butterfly valves offer significant advantages for FPSOs: they are lighter, more compact (shorter face-to-face length), require less operating torque, and are generally more cost-effective. They provide excellent shut-off for isolation services. Gate valves might be preferred for pigging or full-bore flow requirements, but for many isolation and control duties on an FPSO, our fire-safe butterfly valve is a highly efficient solution.
Q8: What documentation accompanies the valve delivery?
A8: Standard documentation includes a Material Test Report (MTR/Certificate of Conformity) for major components, a detailed dimensional drawing, a manual, and a packing list. Additional documents like NDE reports, coating reports, or fire test certificates can be provided as per the purchase order requirements.
