As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve is dedicated to providing robust and reliable flow control solutions for the global energy and process industries. Our High Pressure API 6D Duplex Ball Valve in 2205 Grade, Class 1500 Rating, represents the pinnacle of engineering for severe service applications. Designed to withstand the harshest corrosive and high-pressure environments, this valve is engineered for longevity and zero-leakage performance, ensuring operational safety and minimizing total cost of ownership for our clients worldwide.
This valve is not just a component; it's a critical asset for your pipeline integrity. It combines the superior strength and corrosion resistance of Duplex 2205 stainless steel with the stringent design and testing requirements of API 6D, making it an ideal choice for demanding offshore, subsea, and onshore oil & gas applications, as well as aggressive chemical processing.
Our manufacturing process, certified under ISO9001, guarantees consistent quality and traceability from raw material to finished product. With an annual export value demonstrating our global reach, we understand the diverse requirements of markets from North America to Southeast Asia and are committed to delivering valves that meet and exceed international standards.
- Superior Duplex 2205 Material: Offers an excellent balance of high strength (approximately twice that of standard 316 stainless steel) and outstanding resistance to chloride stress corrosion cracking, pitting, and crevice corrosion. This makes it perfect for seawater, chlorides, and acidic services.
- API 6D & Class 1500 Design: Manufactured in full compliance with API 6D specification for pipeline valves. The Class 1500 (equivalent to PN250) pressure rating ensures reliable operation in high-pressure systems up to 3600+ psi, suitable for mainline isolation and critical service points.
- Advanced Sealing Technology: Features a flexible, reinforced PTFE seat for bubble-tight sealing in standard services. For more abrasive or high-temperature services, metal-seated versions are available upon request, providing extended service life in fire-safe or erosive conditions.
- Robust Construction & Anti-Static Device: The valve incorporates a sturdy stem with an anti-blowout design and ensures continuity between the ball and stem for static electricity dissipation, a critical safety feature for hydrocarbon services.
- Versatile Actuation Options: Can be fitted with manual gear operators for large sizes or automated with pneumatic or electric actuators for remote control and integration into SCADA systems, enhancing operational efficiency.
- Full Port (Full Bore) Design: Standard configuration minimizes pressure drop across the valve, ensuring efficient flow and reducing pumping costs over the system's lifetime.

Q: What are the main advantages of Duplex 2205 over 316 stainless steel for this valve?
A: Duplex 2205 offers roughly double the yield strength and significantly better resistance to chloride-induced stress corrosion cracking (SCC) and pitting. This makes it far more suitable for high-pressure offshore, subsea, and chemical applications where both strength and corrosion resistance are critical. -
Q: Is this valve suitable for sour service (H2S environments)?
A: The Duplex 2205 material has good resistance to sulfide stress cracking (SSC). However, for specific sour service applications defined by standards like NACE MR0175/ISO 15156, material certification and hardness verification can be provided upon request to ensure compliance. -
Q: What is the delivery lead time for a typical order?
A: Lead times vary based on size, quantity, and actuation requirements. Standard sizes often have shorter lead times. Please contact our sales team with your specific needs for an accurate production schedule. -
Q: Can you provide valves with different end connections, like butt weld?
A: Absolutely. While flanged ends are common, we can supply valves with butt weld ends (beveled per ASME B16.25) for permanent, leak-free pipeline connections. Please specify your requirement during inquiry. -
Q: Do you offer a fire-safe version of this ball valve?
A: Yes. We can provide valves with a fire-safe design that complies with API 607 or API 6FA standards. This typically involves secondary metal sealing surfaces that maintain sealing integrity in the event of a fire. This is an optional feature. -
Q: What documentation is provided with the valve?
A: Standard documentation includes a Material Test Report (MTR/Certificate of Conformity), hydrostatic test report, and a detailed packing list. Additional certifications like NDT reports or third-party inspection reports are available upon request. -
Q: How does your ISO9001 certification benefit me as a buyer?
A: Our ISO9001 certification ensures a controlled, consistent, and documented manufacturing process. This translates to reliable product quality, traceability of materials, and a systematic approach to meeting your specifications, reducing procurement risk. -
Q: What after-sales support do you offer?
A: We provide comprehensive technical support, including installation guidance and maintenance recommendations. While we recommend using authorized service centers for major repairs, we can supply genuine spare parts like seats, seals, and stems to extend valve service life.
