As a leading manufacturer with ISO9001 certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing robust and reliable fluid control solutions for demanding industrial and marine environments. Our DN50-DN200 API 6D Marine Ball Valve in A105 Forged Steel with Flanged End is engineered to deliver exceptional performance, safety, and longevity in critical offshore and shipboard applications. With an annual export value exceeding US$1 million, we have established a strong global presence, supplying high-integrity valves to markets across North America, South America, Europe, Asia, and Africa. This valve represents our commitment to combining stringent international standards with superior manufacturing craftsmanship.
This marine-grade ball valve is designed to meet the rigorous requirements of offshore and marine service, where corrosion resistance, high pressure capability, and reliable shut-off are paramount. Constructed from ASTM A105 forged steel, the valve body offers superior strength and durability compared to cast alternatives, making it ideal for high-pressure and high-cycle applications. The full-bore design ensures minimal pressure drop and allows for pipeline pigging, while the robust construction ensures dependable operation even under harsh sea conditions.
Key Features and Technical Advantages:
- API 6D Compliance: Manufactured in strict accordance with API Specification 6D for pipeline valves, ensuring design, material, and testing integrity for the oil and gas industry, including offshore platforms and FPSOs.
- Superior Forged Steel Construction: The A105 forged steel body, bonnet, and ball provide enhanced mechanical properties, better grain structure, and higher impact strength than cast steel, significantly reducing the risk of failure.
- Marine-Optimized Design: Features include anti-static devices, blow-out proof stems, and fire-safe design options (API 607/6FA) to prevent accidents and ensure safety in flammable service environments.
- Versatile End Connections: Available with flanged ends (RF or RTJ) in pressure classes from 150 to 600, ensuring easy and secure integration into existing marine piping systems.
- Extended Service Life: High-performance seat materials like reinforced PTFE, PEEK, or metal seats are available to handle a wide range of temperatures and media, including seawater, crude oil, and chemicals.
- Multiple Actuation Options: Can be supplied with manual lever or gear operation, as well as pneumatic or electric actuators for remote control and automation, suitable for unmanned engine rooms.

The primary benefit for our clients is the assurance of a valve that minimizes downtime and maintenance costs. Its forged construction and API 6D compliance translate to fewer leaks, reduced risk of catastrophic failure, and longer intervals between overhauls. For shipbuilders and offshore operators, this means enhanced operational safety, compliance with class society rules (like ABS, DNV, LR), and protection of valuable assets and personnel. The valve's versatility across sizes and pressure ratings allows for standardized inventory, simplifying procurement and spare parts management for fleet-wide applications.

Frequently Asked Questions (FAQ):
-
Q: Is this valve suitable for seawater service?
A: Yes, when ordered with appropriate trim materials (such as 316 stainless steel trim and special seat materials), this A105 forged steel valve is highly resistant to corrosion from seawater and is commonly used in seawater cooling and firefighting lines. -
Q: What class society approvals do you offer?
A: While standard valves are manufactured to meet the requirements of major class societies (ABS, DNV, BV, etc.), specific approval certificates can be provided upon request and are subject to additional testing and documentation. -
Q: Can you provide valves with pneumatic actuators for remote operation?
A: Absolutely. We offer a complete package including the ball valve fitted with pneumatic actuators (double-acting or spring-return). Actuator specifications (brand, torque, air supply) can be customized based on your system requirements. -
Q: What is the delivery lead time for an order of DN100 Class 300 valves?
A: For standard configurations, the lead time is typically 4-6 weeks. Lead times may vary based on order quantity, specific material requirements, and actuator selection. We provide accurate timelines upon order confirmation. -
Q: How does the fire-safe design work?
A: Our optional fire-safe design incorporates secondary metal seats. In case of a fire that destroys the primary soft seats, the metal seats engage to maintain a seal and prevent leakage, complying with API 607/6FA test standards. -
Q: Do you provide documentation like test reports and material certificates?
A: Yes, we provide a comprehensive documentation package including material test certificates (MTC), factory acceptance test reports per API 598, and a detailed inspection report. This is standard for all our API 6D valves. -
Q: What is the main advantage of forged steel (A105) over cast steel for a marine ball valve?
A: Forged steel has a denser, more uniform grain structure, resulting in higher strength, better impact resistance, and improved fatigue life. This makes it more reliable for the dynamic loads and pressure cycling often encountered in marine applications. -
Q: Are your valves suitable for cryogenic service?
A: The standard valve is rated for -29°C. For cryogenic applications (e.g., LNG), valves with extended bonnets, low-temperature materials, and special seat designs are available. Please inquire with your specific temperature requirements.
