As a specialized manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our premium API 6D Duplex Stainless Steel Ball Valve. Engineered for the most demanding fluid control applications, this valve combines the superior corrosion resistance of a 2507 Super Duplex body with the excellent sealing properties of PTFE seats. Designed to meet rigorous international standards, our valve offers exceptional performance, longevity, and safety in critical industrial environments, providing a dependable solution for global partners in the oil & gas, chemical, and offshore sectors.

Our valve is meticulously crafted to deliver unparalleled value. The core of its performance lies in the advanced material selection and precision engineering.

Key Features & Technical Advantages:

Superior Material Construction: The valve body and key internal components are manufactured from UNS S32750 (2507) Super Duplex Stainless Steel. This material offers a high PREN (Pitting Resistance Equivalent Number) value, providing outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-containing environments.
API 6D Compliance: Designed, manufactured, and tested in full compliance with API 6D specifications for pipeline valves. This ensures robust construction, reliable performance under pressure, and interchangeability of dimensions.
High-Performance Sealing: Utilizes reinforced PTFE (Polytetrafluoroethylene) seats, which offer excellent chemical inertness, a low coefficient of friction, and reliable sealing across a wide temperature range, ensuring bubble-tight shut-off.
Robust Design for High Pressure: The trunnion-mounted ball design provides stability and reduces operating torque, making it suitable for high-pressure and large-diameter applications. It minimizes seat load and wear, extending service life.
Fire-Safe Design (Optional): Available with fire-safe features per API 607/API 6FA standards, where secondary metal seals engage to maintain sealing integrity in the event of a fire, protecting personnel and assets.
Versatile Actuation Options: Can be supplied with manual levers, gear operators, or automated actuators (pneumatic or electric) for remote control and integration into process automation systems.

Frequently Asked Questions (FAQ)

Q: What are the main advantages of 2507 Super Duplex over standard 316 stainless steel?
A: 2507 Super Duplex offers significantly higher strength (approximately double the yield strength) and vastly superior resistance to chloride-induced pitting and stress corrosion cracking, making it essential for aggressive offshore, chemical, and oil & gas environments.
Q: Is this valve suitable for seawater or brine service?
A: Yes, the 2507 Super Duplex material is highly recommended for seawater, brine, and other chloride-rich media due to its excellent pitting and crevice corrosion resistance.
Q: Can you provide valves with different seat materials besides PTFE?
A: Certainly. While PTFE is standard for its wide chemical compatibility, we can offer alternative seats such as reinforced PTFE, PEEK, or metal seats for higher temperatures or more abrasive services upon request.
Q: What pressure classes are available?
A: We typically manufacture valves in pressure classes from Class 150 to Class 1500. Higher classes like Class 2500 can be produced based on specific project requirements and design validation.
Q: Are your API 6D valves fire-safe certified?
A: Fire-safe design is an optional feature. Valves can be manufactured and tested to meet API 607/API 6FA fire-safe standards when specified in the order.
Q: What types of end connections do you offer?
A: Standard end connections are raised face (RF) flanges per ASME B16.5. We also provide ring-type joint (RTJ) flanges and butt-weld (BW) ends per ASME B16.25 to suit different piping system designs.
Q: Do you supply automated actuation systems?
A: Yes. We can supply the valve fully assembled and tested with pneumatic (double-acting or spring-return) or electric actuators, complete with necessary controls, as a complete package.
Q: What is your typical lead time for an order?
A: Lead time depends on the valve size, pressure class, quantity, and any special requirements. For standard specifications, please contact our sales team with your detailed inquiry for an accurate production schedule.
