As a dedicated manufacturer with a proven track record since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in delivering robust and reliable fluid control solutions for the most demanding offshore environments. Our FPSO Offshore Butterfly Valve is engineered to meet the stringent requirements of floating production, storage, and offloading units, where safety, durability, and long-term performance are non-negotiable. Backed by our ISO9001 certified quality management system and an annual export value reflecting global trust, we provide a valve solution that combines advanced engineering with comprehensive documentation, including a Mill Test Report for full traceability and a solid 2-Year Warranty for your peace of mind. This valve is designed not just to function, but to excel in corrosive marine atmospheres, high-pressure crude oil, seawater, and gas service, ensuring uninterrupted operations on your critical asset.
We understand that downtime on an FPSO is incredibly costly. Therefore, every component of our butterfly valve is selected and tested to prevent failure. From the major markets we serve across North America, Europe, Asia, and Africa, feedback consistently highlights the valve's reliability and our responsive support. Choosing our valve means investing in a component that protects your operational integrity and maximizes asset uptime.
Core Design Features & Technical Advantages:
- Superior Corrosion Resistance: Manufactured from grades like Duplex Stainless Steel (UNS S31803/S32205) or specially coated Carbon Steel, the valve body and disc are built to withstand prolonged exposure to seawater, sour service (H2S), and other aggressive chemicals commonly found offshore.
- Bubble-Tight Shut-Off: Features advanced seat designs, including resilient PTFE or EPDM for standard services and metal-seated (Stellite hard-faced) options for high-temperature or abrasive slurry applications, ensuring zero leakage for safety and environmental protection.
- Robust Stem Design: Utilizes a one-piece stem/disc connection or a securely pinned design to prevent blow-out. The stem is often coated or made from corrosion-resistant alloy to prevent seizure and ensure smooth operation over the valve's lifetime.
- Extended Service Life: The design minimizes wear points. Self-lubricating bushings, high-quality bearings, and optimized disc geometry reduce operating torque and prevent premature failure, aligning with the long turnaround cycles of FPSOs.
- Flexible Actuation Compatibility: The valve is designed to interface seamlessly with manual gear operators, electric actuators, or pneumatic/hydraulic actuators, allowing for easy integration into existing FPSO control systems.

Benefits for Your FPSO Operation:
- Enhanced Safety & Environmental Compliance: Reliable shut-off reduces the risk of hydrocarbon leaks, protecting personnel and the marine environment.
- Reduced Total Cost of Ownership (TCO): The durable construction and 2-year warranty lower maintenance frequency, spare part costs, and unplanned downtime expenses.
- Simplified Procurement & Logistics: Supplied with a complete Mill Test Report (MTR) that includes chemical analysis, mechanical tests, and NDE reports (like PMI, UT, MPI), facilitating quick material verification and approval by your QC team.
- Global Service Support: With main export markets spanning five continents and major shipment ports in Shanghai, Guangzhou, Hong Kong, and Beijing, we ensure timely delivery and can coordinate technical support through our network.
Frequently Asked Questions (FAQ):
-
Q: What is included in the Mill Test Report (MTR)?
A: The MTR is a comprehensive document that provides traceability for the valve's main pressure-containing parts. It typically includes material certificates with heat numbers, chemical composition analysis, mechanical property test results (yield strength, tensile strength, elongation), and results of any specified non-destructive examinations. -
Q: How does the 2-year warranty work for offshore applications?
A: Our warranty covers defects in materials and workmanship under normal service conditions for a period of 24 months from the date of shipment. For offshore use, we consider the challenging environment and stand behind the product's durability. Warranty claims are processed efficiently through our technical service team. -
Q: Can this valve be used for seawater cooling service?
A: Yes, it is highly suitable. We recommend specific material combinations like Duplex Stainless Steel body with a Super Duplex or 6-Moly stem and an EPDM seat for optimal resistance to chloride-induced corrosion and marine biofouling. -
Q: What actuation options do you recommend for an FPSO?
A: This depends on the system. For critical ESD (Emergency Shutdown) or process control valves, pneumatic/hydraulic actuators are common for fail-safe operation. For manual isolation valves, high-ratio gear operators are recommended for easier handling of larger sizes under pressure. -
Q: Do you offer fire-safe certified valves?
A> Yes, we can supply valves designed and tested to meet fire-safe standards such as API 607/6FA or ISO 10497. This is a critical option for hydrocarbon service, and it should be specified at the time of inquiry. -
Q: What is your lead time for large-size, customized valves?
A: Lead times vary based on size, material, and customization. Standard configurations typically have shorter lead times. For project-specific requirements, we provide a detailed schedule upon receipt of your technical specifications. Our multiple ports allow flexible shipping planning. -
Q: Can you provide valves with NACE MR0175/ISO 15156 compliance for sour service?
A> Absolutely. We routinely manufacture valves using NACE-compliant materials and processes for service in environments containing H2S. This includes controlled hardness, special heat treatment, and appropriate material selection.
Shanghai Zhibang's commitment to quality is institutionalized through our ISO9001 certification, ensuring every FPSO Offshore Butterfly Valve undergoes rigorous production and testing protocols before it bears our name. Our growing annual export value, serving demanding markets from Northern Europe to Oceania, is a testament to the reliability our partners have come to expect. We don't just supply a valve; we deliver a verified, warranted component backed by manufacturer accountability. This valve represents a strategic investment in the resilience of your FPSO's piping systems.
