As a leading manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our API 609 Large Diameter Butterfly Valve series. Engineered specifically for demanding offshore and marine applications, this valve combines robust construction, precise gear operation, and stringent certification to ensure safe and efficient flow control in critical environments. Since our establishment in 2016, we have dedicated ourselves to producing industrial valves that meet the highest international standards, serving a global clientele across diverse markets from North America to Southeast Asia. Our experience in exporting to over a dozen regions underscores our capability to deliver products that perform reliably under the most challenging conditions.

This series is designed to address the unique requirements of large-diameter piping systems where reliability is non-negotiable. The valve's design and manufacturing adhere to API 609, a standard specifically for butterfly valves, ensuring compatibility and performance in oil, gas, and seawater applications.

Key Features & Technical Advantages:

Certified for Marine & Offshore Use: Holding ABS NK Certification, this valve is approved for use in marine and offshore applications, guaranteeing it meets the rigorous safety and quality standards required for such harsh environments.
Robust Ductile Iron Construction: The valve body is crafted from high-grade ductile iron, offering superior strength, impact resistance, and durability compared to standard cast iron, which is crucial for withstanding the corrosive and high-pressure conditions offshore.
Precise Gear Operation: The gear operator provides significant mechanical advantage, allowing for smooth and controlled opening/closing of large-diameter valves with minimal effort, even under high differential pressures. This ensures operator safety and precise flow modulation.
Wide Size Range: Available in sizes from DN800 to DN1200, this series is ideal for main pipeline isolation, seawater intake/outfall, and other large-bore applications common on offshore platforms, FPSOs, and ships.
Class 150 Pressure Rating: Rated for Class 150 service, the valve is suitable for a wide range of operating pressures encountered in offshore processes, providing a reliable seal and long service life.
Versatile Seat & Disc Options: The seat and disc materials can be customized (e.g., EPDM, NBR, stainless steel) to match specific media compatibility needs, such as handling seawater, crude oil, or chemicals.
Bi-Directional Sealing: Designed to provide effective sealing in both flow directions, enhancing operational flexibility and safety in complex piping layouts.
Low Torque & High Cycle Life: The optimized disc and seat design minimizes operating torque and maximizes cycle life, reducing maintenance frequency and total cost of ownership.

Benefits for Your Offshore Operations:

Enhanced Safety & Compliance: The ABS NK certification provides assurance that the valve meets specific marine industry regulations, reducing project risk and ensuring compliance.
Reduced Maintenance & Downtime: The durable ductile iron construction and reliable gear mechanism lower the risk of failure, leading to less unscheduled maintenance and higher system availability.
Cost-Effective Solution: For large diameters, butterfly valves offer a more compact and economical alternative to gate or ball valves, saving on space, weight, and initial investment.
Global Supply Chain Support: With annual export values between US$1-1.5 million and major shipment ports including Shanghai, Guangzhou, Hong Kong, and Beijing, we ensure timely and efficient logistics to support your global projects.

Frequently Asked Questions (FAQ)

Q: What does the ABS NK Certification mean for this valve?
A: The ABS NK Certification indicates that this butterfly valve has been designed, manufactured, and tested in accordance with the rules and standards set by the American Bureau of Shipping (ABS) and Nippon Kaiji Kyokai (ClassNK). This is a mandatory approval for valves used on classified vessels and offshore structures, ensuring they meet stringent safety and performance criteria for marine environments.
Q: Why is ductile iron chosen for the valve body instead of cast iron?
A: Ductile iron offers significantly higher tensile strength, impact resistance, and elongation properties compared to standard cast iron. In the dynamic and sometimes corrosive offshore environment, this enhanced durability translates to a longer service life, better resistance to shock loads, and reduced risk of catastrophic failure.
Q: Can this valve be equipped with an actuator for remote operation?
A: Yes. While supplied as standard with a manual gear operator, the valve design is compatible with the addition of electric, pneumatic, or hydraulic actuators. The gearbox provides a standard interface for actuator mounting, allowing for easy automation to suit your control system needs.
Q: What flange standards are available?
A: We typically supply valves with ASME B16.5 raised face (RF) flanges as standard. However, to accommodate global projects, we can provide flanges conforming to other prevalent standards such as DIN, JIS, or GB upon request. Please specify your requirement during inquiry.
Q: Is this valve suitable for seawater service?
A: Absolutely. This is a primary application. For seawater, we recommend specific material combinations, such as a ductile iron body with suitable corrosion protection (epoxy coating), a stainless steel disc (e.g., 316SS), and a seawater-resistant elastomer seat (e.g., EPDM). We can advise on the optimal configuration.
Q: What is the typical delivery lead time for an order of DN1000 valves?
A: Lead times vary based on order quantity and specific customization. For standard configurations, typical production lead time ranges from 6 to -10 weeks. Our multiple shipment ports (Shanghai, Guangzhou, Hong Kong, Beijing) facilitate efficient export logistics once production is complete.
Q: Do you provide test reports and documentation with the valves?
A: Yes. As part of our ISO9001 quality procedures, each valve undergoes rigorous testing, including hydrostatic shell tests, seat leakage tests, and operational torque checks. Certified test reports, material certificates, and full documentation pack (including manuals and certification copies) are provided with shipment.
Q: What after-sales support do you offer?
A: We provide comprehensive technical support, including installation guidance and operational advice. While we are a manufacturer based in Shanghai, our extensive export experience to diverse markets means we are accustomed to supporting clients remotely. We also supply spare parts like seal kits to ensure long-term valve maintainability.
