As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing robust and reliable fluid control solutions for demanding industrial applications. Our API 609 Large Diameter Butterfly Valves are engineered specifically for critical service in marine main pipelines, where reliability under pressure and corrosive environments is non-negotiable. This valve combines the stringent design requirements of API 609 with the inherent strength of ductile iron and precise gear operation, delivering a product that ensures long-term performance, safety, and ease of maintenance for your offshore and marine operations.
This large-diameter butterfly valve is designed to handle the rigorous demands of main pipeline systems on vessels and offshore platforms. Its construction and features are tailored for high flow, moderate pressure isolation, and throttling services where space and weight considerations are crucial.
- API 609 Compliant Design: Manufactured in strict adherence to API Standard 609 for butterfly valves, ensuring dimensional interchangeability, material integrity, and performance reliability that meets global industry expectations for oil, gas, and marine applications.
- Robust Ductile Iron Construction: The valve body and disc are crafted from high-grade ductile iron (nodular cast iron), offering superior tensile strength, impact resistance, and durability compared to standard cast iron, making it ideal for the dynamic loads and potential water hammer in marine pipelines.
- Large Diameter Range (DN800-DN1200): Specifically designed for main line applications, this valve is available in sizes from DN800 (32") to DN1200 (48"), facilitating high-volume fluid transfer essential for ballast, cooling, fuel, and other marine systems.
- Precise Gear Operation: Equipped with a manual gear operator, this valve provides significant mechanical advantage, allowing for smooth and manageable opening and closing even against high flow pressures. The gearbox design ensures precise positioning for throttling and secure shut-off.
- Class 150 Pressure Rating: Rated for ASME Class 150 (PN16/20), suitable for a wide range of moderate-pressure services found in marine pipeline networks, offering a reliable seal and structural safety margin.
- Versatile Seat Options: Available with various seat materials (e.g., EPDM, Nitrile, Viton) to ensure compatibility with seawater, hydrocarbons, chemicals, or other media typical in marine environments. Metal-seated versions are available for higher temperature or more abrasive services.
- Corrosion Protection: Standard exterior coating is a high-quality epoxy paint, providing excellent resistance to saltwater spray and atmospheric corrosion. Internal coatings or cathodic protection options can be explored for specific project requirements.
- Compact & Lightweight Design: Compared to gate valves of similar diameter, butterfly valves offer a significantly more compact and lighter design, reducing structural load on pipe supports and simplifying installation in space-constrained engine rooms or deck areas.
- Bi-Directional Sealing: The valve design typically provides effective bi-directional shut-off, enhancing operational flexibility and safety in pipeline systems where flow direction might change.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of specifying an API 609 butterfly valve over a standard design?
A: API 609 is a globally recognized standard specifically for butterfly valves in critical services like oil, gas, and marine. It defines stringent requirements for design, materials, testing, and dimensions, ensuring higher reliability, interchangeability, and acceptance in major international projects compared to generic designs. -
Q: Why is ductile iron preferred for large diameter marine valves?
A: Ductile iron offers a superior strength-to-weight ratio and much higher impact and fatigue resistance than standard cast iron. This is crucial for large valves in marine pipelines that may experience vibration, water hammer, and dynamic loads, significantly reducing the risk of catastrophic failure. -
Q: Can this valve be operated remotely or with an actuator?
A: Yes, absolutely. While supplied with a standard manual gear operator, the valve stem is designed to be compatible with various electric, pneumatic, or hydraulic actuators. We can provide the valve prepared for actuator mounting or supply a complete actuated package upon request. -
Q: Are lug-type end connections available for DN1000 and larger sizes?
A: Yes, lug-type ends are available across the entire size range (DN800-DN1200). The lug design is often preferred for end-of-line service or where pipeline sections need to be isolated independently, as it allows bolt-on connection to flanges without needing a continuous bolt through the valve. -
Q: What kind of sealing performance can I expect for seawater service?
A: For seawater, we typically recommend an EPDM or Viton seat paired with a stainless steel stem (316 grade). This combination provides excellent resistance to saltwater corrosion and ensures a bubble-tight seal in accordance with API 598 or similar standards for low-pressure closure tests. -
Q: How is the valve protected against external corrosion in a marine environment?
A: The standard protection is a high-build epoxy coating, which is highly resistant to salt spray. For submerged or splash zone applications, more specialized coatings like fusion-bonded epoxy (FBE) or the addition of sacrificial anode cathodic protection can be discussed as custom options. -
Q: What is the typical delivery lead time for a DN1200 valve?
A: Lead times vary based on order quantity, specific configuration (seat material, end type), and current production schedule. Generally, for standard configurations, lead times for large diameters range from 8 to 12 weeks. We provide accurate timelines upon receipt of your detailed inquiry. -
Q: Do you provide technical documentation and certifications with the valves?
A: Yes, each valve shipment is accompanied by essential documentation, which typically includes a Material Test Report (MTR), Certificate of Conformity, hydrostatic test report, and detailed dimensional drawings. Additional certifications are available upon request.
