As a professional manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd specializes in producing high-performance valves for demanding industrial applications. Our API 6D Marine Full Bore Ball Valve with Fire Safe Design and DNV LR Approval represents our commitment to quality and safety in the marine and offshore sectors. Engineered to meet rigorous international standards, this valve offers superior flow control, enhanced safety in fire scenarios, and the trusted certification required for critical offshore and shipboard installations, providing our global clients with a reliable and compliant solution.

This valve is meticulously designed to address the specific challenges of marine and offshore oil & gas operations. Its core features and technical specifications ensure optimal performance and longevity in harsh environments.

API 6D Compliance: Manufactured in accordance with API Specification 6D for pipeline valves, ensuring design, material, and testing standards suitable for hydrocarbon service.
Full Bore Design: Provides a ball port diameter essentially equal to the pipeline inner diameter, minimizing flow restriction, reducing pressure drop, and allowing for easier pipeline cleaning or pigging operations.
Fire Safe Design: Incorporates secondary metal sealing seats. In a fire event where primary soft seals (e.g., PTFE) are compromised, the metal seats engage to maintain a seal and prevent catastrophic leakage, meeting recognized fire test standards.
DNV LR Approval: Certified by DNV (Det Norske Veritas) or Lloyd's Register, leading maritime classification societies. This approval is crucial for valves used on classified vessels and offshore platforms, verifying that the product meets specific safety, materials, and performance criteria.
Robust Construction: Typically fabricated from materials like carbon steel or stainless steel, with options for other alloys to suit corrosive seawater or process fluid environments.
Versatile Operation: Available in manual handwheel, gear-operated (for larger sizes/high pressure), or actuated (electric, pneumatic, hydraulic) versions for remote or automated control.
Enhanced Durability: Features such as reinforced stem design, anti-blowout stem construction, and extended body/bonnet bolting contribute to high pressure integrity and long service life.

The following table outlines typical key specifications for this product line. Specific values may vary based on size, material, and customer requirements.

Parameter	Description / Typical Range
Design Standard	API Specification 6D
Fire Safe Standard	Complies with API 6FA, ISO 10497, or similar fire test requirements
Approval/Certification	DNV (Det Norske Veritas) or Lloyd's Register (LR) Type Approval
Size Range (Nominal)	Commonly from 2" (DN50) to 24" (DN600), other sizes customizable
Pressure Class	ASME Class 150, 300, 600, 900, etc., depending on design
Body Material	WCB Carbon Steel, CF8/CF8M Stainless Steel, Duplex Steel, other alloys optional
Seat Material (Primary)	PTFE, Reinforced PTFE, PEEK, etc.
Seat Material (Secondary/Fire Safe)	Stainless Steel, Inconel, or other suitable metals
End Connection	Flanged (RF, RTJ), butt-weld ends optional
Operation	Manual, Gear Operated, with Actuator Mounting Pad (for automated options)

The advantages of choosing our API 6D Marine Full Bore Fire Safe Ball Valve translate into significant benefits for your projects:

Regulatory Compliance & Market Access: The DNV LR approval is often a mandatory requirement for equipment on classified ships and offshore installations. Using our pre-approved valve simplifies your procurement and compliance process, speeding up project timelines.
Operational Safety & Risk Mitigation: The fire-safe design provides an essential layer of protection. It helps contain fluids during an emergency fire situation, potentially preventing escalation of the incident, protecting assets, and ensuring personnel safety.
Efficient System Performance: The full bore design ensures minimal flow resistance, which can lead to lower pumping energy costs, higher throughput, and facilitates necessary maintenance procedures like pipeline pigging.
Reliability in Severe Conditions: Built to API 6D standards with quality materials, these valves offer dependable performance under high pressure, corrosive environments, and mechanical stress typical of marine applications.
Global Supply Chain Support: With our annual export value ranging between US$1 Million and US$1.5 Million, we have established a robust supply chain serving markets across North America, South America, Europe, Asia, Africa, and Oceania. We ship from major ports like Shanghai, Guangzhou, Hong Kong, and Beijing, ensuring timely delivery to your location.

Frequently Asked Questions (FAQ)

What does "DNV LR Approval" mean for this valve?
It signifies that the valve design, materials, and manufacturing process have been assessed and certified by either DNV (Det Norske Veritas) or Lloyd's Register, leading maritime classification societies. This approval is often required for valves used on ships, offshore platforms, and other marine structures that are "classed" by these organizations, ensuring compliance with their safety rules.
How does the "Fire Safe" feature work in this ball valve?
The valve is designed with dual sealing systems. Primary soft seals (like PTFE) provide normal sealing. In a fire, these may degrade. The secondary metal seals (e.g., stainless steel) are then designed to engage and maintain a seal, preventing major leakage. The design must pass standardized fire tests (e.g., API 6FA) to be considered fire safe.
What is the advantage of a "Full Bore" design compared to a standard port ball valve?
A full bore valve has a ball port diameter nearly equal to the pipe's inner diameter. This reduces flow turbulence and pressure loss, allows for higher flow capacity, and enables tools like pipeline "pigs" to pass through for cleaning or inspection, which is not possible with reduced port valves.
Can this valve be used for applications other than marine/offshore?
Yes. While specifically designed and certified for marine use, its API 6D and fire-safe qualifications make it suitable for other demanding hydrocarbon processing applications onshore, such as in refineries, chemical plants, or high-pressure pipelines where similar safety and performance standards are required.
What material options are available for the body and internals?
Standard materials include carbon steel (WCB) and stainless steel (CF8/CF8M). For more corrosive environments (e.g., seawater, sour service), materials like duplex stainless steel, super duplex, or nickel alloys can be offered as customizable options upon request.
Is the valve available with actuators for automated control?
Yes. The valve is typically designed with a standardized mounting pad for actuators. We can supply the valve ready for actuator installation, or provide integrated packages with electric, pneumatic, or hydraulic actuators based on your control system requirements.
What pressure classes are typically offered?
Common pressure classes align with ASME standards, such as Class 150, 300, 600, and 900. The specific class depends on the valve size, design, and application pressure requirements. Higher classes are available for specialized designs.
What documentation is provided with the DNV LR approved valves?
Along with the valve, we provide a certificate of conformity or type approval certificate from DNV or LR, material test reports, pressure test reports, and other quality documentation as per the certification requirements and customer specifications.
