Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, is a professional manufacturer dedicated to producing high-performance valves for demanding industrial applications. Our API 6D Marine Ball Valve Compliant with DNV LR Standards represents our commitment to quality and reliability in the offshore sector. Designed specifically for harsh marine environments, this valve ensures safe, efficient, and long-lasting operation in critical pipeline systems, helping clients mitigate risks and reduce maintenance costs.

This valve is engineered to meet the rigorous requirements of offshore oil & gas, shipbuilding, and marine infrastructure projects. Its compliance with both API 6D and DNV LR standards guarantees that it adheres to internationally recognized specifications for design, materials, testing, and performance under extreme conditions.

Key Features & Technical Specifications:

Dual Standard Compliance: Certified to meet both API 6D (for pipeline valves) and DNV LR (for marine applications), ensuring global acceptance and suitability for offshore projects.
Robust Construction: The valve body is typically manufactured from forged or cast carbon steel (WCB, LCB) or stainless steel (304, 316), providing excellent resistance to corrosion, pressure, and impact.
Advanced Sealing System: Utilizes high-performance sealing materials such as reinforced PTFE or metal seals, offering superior leak-proof performance and durability against seawater, hydrocarbons, and abrasive media.
Fire Safe Design: Optional fire-safe construction available, meeting API 607/6FA standards, which is critical for safety in offshore platforms.
Full Port Design: Minimizes flow resistance and pressure drop, ensuring efficient fluid transfer and reducing energy consumption in pipelines.
Versatile Operation: Available in manual handwheel, gearbox operated, or electric actuator configurations to suit different automation and accessibility needs.
Extended Service Life: Precision machining and surface treatments (e.g., coatings, galvanization) enhance wear resistance and prolong operational lifespan in corrosive environments.
Easy Maintenance: Top-entry or side-entry design allows for inline maintenance and seal replacement without removing the valve from the pipeline, saving time and labor.

Detailed Technical Parameters:

Parameter	Specification / Range
Size Range (Nominal Diameter)	DN15 (½") to DN600 (24")
Pressure Rating (PN)	PN16, PN25, PN40, PN64, PN100
Temperature Range	-20°C to 200°C (Standard); Extended ranges customizable
Body Material Options	Carbon Steel (A216 WCB, LCC), Stainless Steel (A351 CF8/CF8M), Duplex Steel

Frequently Asked Questions (FAQ):

Q: What is the significance of DNV LR compliance for a marine ball valve?
A: DNV LR (Det Norske Veritas & Lloyd's Register) standards are specific to marine and offshore equipment. Compliance ensures the valve is designed, manufactured, and tested to perform reliably in harsh sea environments, including resistance to corrosion, vibration, and extreme pressures, which is crucial for safety and certification in offshore projects.
Q: How does API 6D differ from other API valve standards?
A: API 6D is specifically for pipeline valves (ball, gate, check, etc.), covering design, materials, testing, and dimensions. It complements DNV LR by ensuring the valve meets high-performance requirements for onshore and offshore pipeline systems, focusing on sealing, pressure rating, and operational life.
Q: Can this valve be used for subsea applications?
A: Yes, with proper customization. While the standard valve is suitable for offshore platform piping, we can offer modifications such as special coatings (e.g., epoxy), extended material grades (duplex steel), and enhanced sealing for deeper subsea applications. Specifications should be discussed based on your project depth and media.
Q: What are the available actuator options for remote operation?
A: We provide a range of actuation solutions: manual handwheel, gear operators for high-torque applications, electric actuators (with various control signals), and pneumatic actuators. The choice depends on your automation system, available power source, and required response time.
Q: Is fire-safe certification available?
A: Yes, fire-safe design is an optional feature. Valves can be manufactured to meet API 607/6FA or similar fire-test standards, where the sealing system maintains leak-tightness even under high-temperature fire conditions, a critical requirement for many offshore oil & gas facilities.
Q: What is the typical delivery time for these valves?
A: Delivery time depends on size, material, and customization level. For standard sizes and materials, lead time is generally shorter. As we ship from multiple ports (Shanghai, Guangzhou, Hongkong, Beijing), logistics are flexible. Please inquire with your specific requirements for an accurate timeline.
Q: Do you provide testing reports and certification documents?
A: Yes. As part of our ISO9001 system, valves undergo rigorous testing (pressure, leakage, material, etc.). Test reports and copies of relevant compliance statements (for API 6D and DNV LR) are provided with the product shipment to support your project documentation.
Q: Can the valve handle corrosive media like seawater or sour gas?
A: Absolutely. By selecting appropriate body materials (e.g., stainless steel 316, duplex steel) and seal materials (PTFE, metal), the valve can be configured for corrosive environments. For sour gas (H2S containing), NACE MR0175 compliant materials can be specified.
