As a professional manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our High-Pressure Marine Ball Valve series, engineered specifically for the demanding environments of Floating Production Storage and Offloading (FPSO) units and other critical marine applications. Established in 2016 and backed by ISO9001 certification, our company leverages extensive manufacturing expertise to deliver valves that meet stringent international standards, ensuring safe and efficient operation for your offshore projects. This valve is designed to provide exceptional sealing performance and durability under high-pressure conditions, making it a trusted component for fluid control systems worldwide.
Our High-Pressure Marine Ball Valve is constructed to comply with DIN 3357 standards and features a PN100 pressure rating, indicating its suitability for severe service conditions. The valve is available in a comprehensive size range from DN15 to DN200, offering flexibility for various pipeline configurations on FPSOs, including cargo handling, ballast, fuel, and process lines.
Key Features and Technical Advantages:
- Robust Construction: The valve body is typically manufactured from forged carbon steel (A105) or stainless steel (CF8M/316), providing excellent resistance to corrosion and mechanical stress in marine environments.
- Superior Sealing: Utilizes advanced seat materials such as reinforced PTFE or metal-seated designs for bubble-tight shut-off, even after prolonged exposure to high pressure and abrasive media.
- Fire-Safe Option: Available with fire-safe design per API 607/API 6FA standards, featuring secondary metal seals that maintain integrity in the event of a fire, a critical safety feature for offshore installations.
- Low Torque Operation: The precision-machined ball and stem assembly ensures smooth, low-friction operation, which is essential for manual levers or when paired with gear operators for larger sizes.
- Extended Service Life: Anti-static and blow-out proof stem design, along with high-grade sealing components, minimizes maintenance requirements and maximizes valve lifespan.

Frequently Asked Questions (FAQ):
Q1: Is this valve suitable for seawater service on an FPSO?
A: Yes, it is highly suitable. When specified with appropriate materials like 316 stainless steel or duplex steel, the valve offers excellent corrosion resistance against seawater, making it ideal for ballast, cooling, or firewater systems.
Q2: What does the PN100 rating mean for my application?
A: PN100 indicates a nominal pressure rating of 100 bar. This means the valve is designed and tested to safely handle working pressures up to this level, which is common in high-pressure hydrocarbon processing and transfer lines on FPSOs.
Q3: Can I get this valve with pneumatic actuation?
A: Absolutely. While the standard offering is manual operation, pneumatic (or hydraulic/electric) actuators can be supplied as an optional accessory. We can configure the valve with a double-acting or spring-return actuator based on your control system requirements.
Q4: How does the fire-safe feature work?
A: In a fire-safe design, the primary soft seals (like PTFE) are supplemented by secondary metal-to-metal seals (e.g., between the ball and seat). In a fire event where the soft seals degrade, these metal seals engage to provide a continued barrier against leakage, meeting critical safety standards.
Q5: What is the lead time for an order of DN150 valves?
A: Lead times vary based on order quantity, material selection, and optional features. For standard carbon steel DN150 valves, typical production time is 4-6 weeks. We recommend contacting our sales team with your specific needs for an accurate schedule.
Q6: Do you provide full documentation and certification?
A: Yes, we provide comprehensive documentation, including material certificates, pressure test reports, and a certificate of conformity. Documentation packages can be customized to meet project or end-client specifications.
Q7: Are other connection standards besides flanged available?
A: Yes. While flanged connections per DIN/ANSI standards are most common for this pressure class, we can also provide threaded (NPT, BSP) ends or weld-end connections for specific DN sizes upon request.
Q8: What kind of testing is performed on each valve?
A: Every valve undergoes rigorous testing, which typically includes a hydrostatic shell test (at 1.5x PN), seat leakage test, and operational torque check. Additional tests like fire testing or cryogenic testing can be arranged for specialized orders.
