As a leading manufacturer with a strong global footprint, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance API 609 Compliant Duplex 2205 Butterfly Valve. Engineered for demanding industrial applications, this valve combines superior corrosion resistance with a robust lugged body and certified fire-safe design, ensuring reliable isolation and control in critical processes. Our commitment to quality, backed by our ISO9001 certification and annual export value of US$1-1.5 million, guarantees a product built for longevity and performance across diverse markets from North America to Southeast Asia.

This valve is specifically designed to meet the rigorous standards of modern industry. Its core construction from Duplex 2205 stainless steel provides an exceptional strength-to-weight ratio and outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-containing environments. The lugged body design allows for easy installation and removal without disturbing the pipeline, making it ideal for system maintenance and end-of-line services.

Key Features & Technical Advantages:

Premium Material: The Duplex 2205 body, disc, and stem offer superior mechanical properties and corrosion resistance compared to standard 316 stainless steel, extending service life in aggressive media.
API 609 Compliance: Manufactured in strict adherence to API 609 standards for butterfly valves, ensuring dimensional interchangeability, performance reliability, and global acceptance.
Fire-Safe Design: The valve is designed and tested to provide a tight seal in the event of a fire, preventing catastrophic fluid release. This is a critical safety feature for oil & gas and chemical applications.
Versatile Pressure Rating: Available in pressure classes from Class150 to Class600, providing flexibility for a wide range of system pressure requirements.
Robust Lugged Body: The lugged design features threaded inserts, allowing the valve to be bolted between two pipeline flanges with a dead-end service capability on one side.
Low Torque Operation: The streamlined disc design and high-quality seat materials ensure low operating torque, reducing the size and cost of required actuators.
Multiple Actuation Options: The valve is compatible with manual lever handles, gear operators, as well as pneumatic and electric actuators, offering complete control flexibility.

Frequently Asked Questions (FAQ):

Q: What is the main advantage of using Duplex 2205 over standard 316 stainless steel?
A: Duplex 2205 offers approximately twice the yield strength and significantly better resistance to chloride-induced stress corrosion cracking and pitting. This makes it far more suitable for harsh offshore, chemical, and pulp & paper applications.
Q: Can this lugged valve be used for dead-end service?
A: Yes, precisely. The lugged body design with threaded inserts allows the valve to be installed between two flanges and bolted securely, permitting one side of the pipeline to be blanked off for maintenance or as an endpoint.
Q: What does "Fire-Safe Design" mean for this butterfly valve?
A: It means the valve is engineered to maintain a seal (or a specified leakage rate) for a defined period under high-temperature fire conditions, preventing the escalation of a fire by containing the fluid. Specific test standards like API 607 can be followed upon request.
Q: Is this valve suitable for throttling control?
A: While primarily designed for on/off service, with the appropriate actuator (electric or pneumatic) and characterized disc options, it can be used for moderate throttling duties. For precise control, specific engineering review is recommended.
Q: What types of actuators are compatible?
A: The valve is prepared for a wide range of actuators. We can supply it with a manual lever, a gearbox for higher torque, or it can be fitted with pneumatic (double-acting or spring-return) and electric actuators from various brands to meet your automation needs.
Q: Do you offer different seat materials?
A: Absolutely. Standard seats are PTFE-based for excellent sealing and chemical resistance. We also offer reinforced PTFE for improved wear, and metal seats (like Inconel or Stellite) for high-temperature applications above the limits of polymeric seats.
Q: What documentation is provided with the valve?
A: Standard documentation includes a material test certificate (3.1 or 3.2 per EN 10204 optional), hydrostatic test report, and a dimensional drawing. Full certification packages, including fire-safe test reports, are available upon request.
Q: What is your lead time for an order of Class600 valves?
A: Lead times vary based on order quantity, actuation requirements, and specific certifications. Generally, for standard configurations, we maintain competitive lead times. Please inquire with your detailed specifications for an accurate timeline.
