As a specialized manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. provides engineered solutions for demanding offshore applications. Our certified marine butterfly valves are specifically designed and documented for Floating Production, Storage, and Offloading (FPSO) vessels, where reliability, safety, and full traceability are non-negotiable. We understand the critical nature of fluid control in offshore environments, and our valves are built to withstand harsh marine conditions while ensuring long service life and minimal maintenance. With an annual export value reflecting our global reach, we supply valves that meet the exacting standards of shipyards, engineering contractors, and offshore operators worldwide. This product represents our commitment to delivering not just a component, but a fully documented, certified package that simplifies integration and compliance for your FPSO project.
Core Design & Construction Features:
- Robust Disc & Stem Assembly: The valve features a precision-machined disc that provides a bubble-tight shut-off. The stem is designed as a one-piece or two-piece configuration, securely fastened to prevent blow-out, and is isolated from the media to ensure smooth operation and corrosion resistance.
- Advanced Seat & Liner Technology: Utilizing elastomers like EPDM or NBR for standard services and Viton or PTFE for aggressive chemicals, the seat is resilient and provides excellent sealing. The liner is often bonded or locked into the valve body, creating a full-circle seal that prevents media ingress into the body cavity.
- Corrosion Protection for Marine Service: All external and internal wetted surfaces are treated with marine-grade coatings. Options include epoxy coatings, galvanization, or specific stainless steel grades (CF8M/316) to combat saltwater spray, atmospheric corrosion, and the corrosive cargoes handled on FPSOs.
- Multiple Actuation Options: To suit various automation levels on an FPSO, the valve can be fitted with a manual lever, a precision gearbox for high-torque applications, or automated actuators (electric or pneumatic) for remote operation integrated into the vessel's control system.
- Bi-Directional Flow Capability: Engineered for versatility in piping systems, our butterfly valves typically offer reliable sealing against pressure from either direction, simplifying installation and system design.
Technical Specifications & Compliance:
The valves are manufactured to international standards commonly specified in offshore projects. Key specifications are summarized below:
| Parameter | Specification / Range |
| Design Standard | API 609, ISO 5752, BS EN 593 |
| Face-to-Face | Per API 609 / ISO 5752 |
| Pressure Test | Shell: 1.5x PN, Seat: 1.1x PN per API 598 |
| Fire Safe Design | Optional, meeting API 607/ISO 10497 requirements |
| Leakage Class | Class VI (Bubble-tight) or better per MSS-SP-61 |
The Full Technical Documentation Package – Your Compliance Advantage:
What sets this valve apart for FPSO applications is the comprehensive documentation provided, which is essential for class approval and operational audits.
- Material Certificates (3.1/3.2): Full traceability for all primary components (body, disc, stem, seat) with chemical and mechanical test reports from certified mills.
- Manufacturing & Test Records: Detailed records of machining, assembly, and the full battery of pressure tests (hydrostatic, pneumatic seat) with signed reports and charts.
- Dimensional Inspection Report: As-built dimensions confirming compliance with ordered specifications and relevant standards.
- Surface Treatment Certificates: Documentation for coatings, including type, thickness, and adhesion test results.
- Packing List & Quality Plan: Clear documentation for shipment and evidence of a controlled manufacturing process under our ISO9001 system.
- Operation & Maintenance Manual: Detailed instructions for installation, commissioning, and routine maintenance to ensure optimal performance.
Benefits for Your FPSO Project:
- Expedited Class Approval: The complete documentation package is formatted to meet the requirements of major classification societies (e.g., ABS, DNV, Lloyd's Register), significantly reducing the time and cost associated with material review and approval.
- Enhanced Operational Safety & Reliability: Certified materials and rigorous testing ensure the valve performs reliably in critical services, contributing to the overall safety integrity of the FPSO.
- Reduced Lifecycle Costs: Durable construction and proper documentation lead to fewer failures, easier maintenance, and better spare parts management over the vessel's lifespan.
- Global Supply Chain Support: With established export channels to key markets including North America, Europe, Southeast Asia, and the Middle East, we ensure timely delivery to major shipbuilding and offshore hubs from ports like Shanghai, Guangzhou, and Hong Kong.
Frequently Asked Questions (FAQ):
-
Q: What specific certifications are included with the valve?
A: Each valve is supplied with a comprehensive package including material certificates (often 3.1 or 3.2 per EN 10204), manufacturing and test reports, and a certificate of conformity. The company's manufacturing process is certified to ISO9001, ensuring consistent quality control. -
Q: Can these valves be supplied with fire-safe certification?
A: Yes, fire-safe design is an available option. Valves can be manufactured and tested to meet the requirements of standards such as API 607 or ISO 10497, which is crucial for certain applications on an FPSO. Please specify this requirement during inquiry. -
Q: What is the typical lead time for an order?
A: Lead time varies based on size, material, actuation type, and order quantity. Standard configurations may have shorter lead times, while customized or fire-safe versions require additional manufacturing and testing periods. A specific timeline can be provided upon receipt of your detailed specifications. -
Q: Do you provide support for actuator selection and mounting?
A: We offer technical support for actuator selection based on your required torque, available power source (electric/pneumatic), and control signal. We can supply the valve as a complete package with a mounted and tested actuator, ready for installation. -
Q: How do you ensure corrosion resistance for long-term marine exposure?
A> We employ several strategies: selection of appropriate base materials (e.g., stainless steel 316), application of high-performance epoxy or other marine-grade coatings to external surfaces, and the use of corrosion-resistant trim. The specific protection method is tailored to the service environment. -
Q: What after-sales support and warranty do you offer?
A: We provide an operational manual and are available for technical consultation. A standard warranty covers defects in materials and workmanship for a specified period from shipment. Extended warranty or service agreements can be discussed. -
Q: Can you manufacture valves to client-specific standards or drawings?
A> Yes, as a manufacturer, we have the capability to produce valves according to client-provided specifications, drawings, or unusual standard requirements, subject to technical review. This is common for major offshore projects. -
Q: What are the main shipping terms and ports?
A: We commonly ship FOB, CIF, or CFR from major Chinese ports including Shanghai, Guangzhou, and Hong Kong, facilitating logistics to our global markets in the Americas, Europe, Asia, Africa, and Oceania.
