Key Features and Technical Advantages:
- Marine-Grade 316 Stainless Steel Construction: Offers exceptional corrosion resistance against seawater, saline atmospheres, and various chemicals, ensuring long service life in demanding environments.
- API 6D Design Compliance: Manufactured according to the API 6D specification for pipeline valves, ensuring design integrity, pressure handling capability, and interoperability within standardized systems.
- Trunnion Mounted Ball Design: The ball is supported by trunnions, reducing operating torque and wear on seals. This design provides higher stability under pressure, minimizes shaft deflection, and is suitable for high-pressure applications.
- Low Torque Operation: Optimized sealing mechanisms and bearing designs result in significantly lower operating torque. This facilitates easier manual operation, reduces the size and cost of actuation systems, and lowers maintenance frequency.
- Enhanced Sealing Performance: Utilizes advanced seat materials (options available) that provide reliable sealing even under varying pressures and temperatures, minimizing leakage risks.
- Robust Stem and Anti-Blowout Design: Features a sturdy stem design with anti-blowout features to prevent stem ejection under high pressure, enhancing safety.
- Fire Safe Option Available: Can be configured with fire-safe design elements to meet specific safety standards for offshore platforms.
- Versatile End Connections: Typically supplied with flanged ends per standard dimensions (ASME, DIN, JIS, etc.), with other connection types customizable upon request.

Frequently Asked Questions (FAQ)
Q1: What makes this valve "Marine Grade"?
A: The "Marine Grade" designation primarily comes from its construction material – 316 Stainless Steel, which offers superior resistance to corrosion from seawater and salty environments. Additionally, its design per API 6D and robust trunnion construction ensure it meets the performance and safety requirements typical of marine and offshore applications.
Q2: How does the trunnion mounted design benefit operation?
A: In a trunnion mounted design, the ball is supported on two fixed trunnions (pins). This stabilizes the ball, significantly reducing the operating torque required to turn it compared to floating ball designs. It also minimizes wear on the seats, extends seal life, and provides better performance under high pressure.
Q3: Is the low torque operation suitable for manual use only?
A: No, the low torque design benefits both manual and actuated operations. For manual valves, it makes opening and closing easier. For actuated valves (electric, pneumatic, hydraulic), it allows for the use of smaller, less powerful, and more cost-effective actuators, reducing overall system cost and energy consumption.
Q4: What pressure classes are available for this API 6D ball valve?
A: We can manufacture this valve in common pressure classes such as ANSI 150, 300, 600, and higher. The specific class depends on your application requirements. Please contact us with your pressure rating needs for a precise offering.
Q5: Can this valve be customized for specific connection standards or sizes?
A: Yes, customization is a key part of our service. While flanged connections are standard, we can provide valves with welded ends or other connection types. The size range is also flexible – we produce valves from smaller diameters up to large sizes required for main pipelines. Provide your specifications for a tailored solution.
Q6: Does the valve come with any specific certifications like CE or API?
A: The valve is designed per the API 6D standard. Our manufacturing facility operates under an ISO9001 Quality Management System, which ensures consistent quality control. For specific product certifications like CE marking or API monogram, please inquire as these can be arranged based on project requirements and applicable standards.
Q7: What are the typical applications for this valve beyond marine use?
A: While optimized for marine environments, its robust 316 SS construction and API 6D design make it suitable for other demanding industries such as offshore oil & gas, chemical processing plants (especially with corrosive media), power generation, and water treatment facilities where corrosion resistance and reliable sealing are critical.
Q8: How does your company ensure timely delivery to international markets?
A: We utilize multiple major ports of shipment including Shanghai, Guangzhou, Hong Kong, and Beijing. This logistical flexibility allows us to optimize shipping routes and times based on your destination. Our experience exporting to a wide range of global markets helps us manage efficient supply chains to meet delivery schedules.
