As a leading valve manufacturer based in Shanghai with extensive experience in the global marine and offshore sectors, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our premium DIN 3357 Marine Ball Valve. Engineered specifically for the demanding environments of Floating Production, Storage, and Offloading (FPSO) units, this forged steel valve is built to deliver reliable, long-lasting performance under high pressure (PN100) conditions. Our commitment to quality, backed by ISO9001 certification, ensures that every valve meets stringent international standards, providing our clients in North America, South America, Europe, Asia, Africa, and Oceania with a critical component they can trust for their most vital fluid control applications.
Product Features & Technical Advantages:
- Robust Forged Steel Construction: The valve body, ball, and stem are forged from high-grade steel, offering superior mechanical strength, impact resistance, and durability compared to cast alternatives. This is crucial for withstanding the dynamic loads, vibrations, and potential pressure surges encountered on FPSO vessels.
- High-Pressure Design (PN100): Rated for PN100 (approximately 10 bar/145 psi, with specific material-dependent pressure-temperature ratings), this valve is designed to handle high-pressure service in seawater cooling, firefighting, fuel oil, and other essential marine piping systems.
- DIN 3357 Standard Compliance: Manufactured in accordance with DIN 3357 standards for metal-seated ball valves, ensuring dimensional accuracy, interchangeability, and compliance with many European and international marine specifications.
- Flanged Connection for Secure Installation: Features standard flanged ends (configurable to DIN or ANSI standards upon request), facilitating a secure, leak-proof connection to the pipeline. This design allows for easier installation, maintenance, and replacement.
- Bubble-Tight Sealing: Utilizes advanced seat materials like PTFE or reinforced PTFE, providing excellent chemical resistance and a bubble-tight seal in both directions, ensuring zero leakage and safe operation.
- Fire-Safe Design Option: Available with fire-safe features (upon request), where the seat design provides a secondary metal-to-metal seal in the event of a fire, preventing catastrophic failure.
- Low Torque Operation: The precision-machined ball and low-friction seats ensure smooth, low-torque operation, whether operated by a manual lever, gearbox, or actuator, reducing operator effort and wear.
- Corrosion Protection: External surfaces are treated with robust coatings (epoxy or similar) suitable for harsh marine environments, offering enhanced resistance to saltwater corrosion and atmospheric degradation.

Frequently Asked Questions (FAQ):
Q1: Is this valve suitable for seawater service on an FPSO?
A: Yes, absolutely. The forged steel body offers excellent strength, and we can provide specific material grades (like AISI 316/316L stainless steel) and specialized coatings to provide superior corrosion resistance against seawater. The seat materials are also selected for compatibility.
Q2: Can you supply the valve with ANSI flanges instead of DIN flanges?
A: Certainly. While it conforms to the DIN 3357 standard for design, we frequently manufacture these valves with ANSI B16.5 flanges (e.g., ANSI 150 or 300) to match specific project requirements in the Americas and other regions. Please specify your flange standard during inquiry.
Q3: What is the main advantage of forged steel over cast steel for this application?
A: Forged steel has a denser, more uniform grain structure, resulting in higher tensile strength, better impact toughness, and greater fatigue resistance. For the high-stress, critical applications on an FPSO, forged construction provides a significant safety and reliability margin.
Q4: Do you offer actuated versions of this ball valve?
A: Yes, we do. The valve can be fitted with pneumatic (double-acting or spring-return), hydraulic, or electric actuators for remote or automated control. We can provide a complete package including the actuator, positioners, and limit switches.
Q5: What documentation and certifications come with the valve?
A: Each valve is supplied with a standard documentation package including a Material Test Certificate (MTC), Product Data Sheet, and dimensional drawing. Additional certifications like NACE MR0175, NORSOK, or specific classification society approvals (DNV, ABS, LR, etc.) can be arranged upon request.
Q6: What is the typical delivery lead time for an order?
A: Lead time depends on order quantity, size, and material specifications. For standard configurations, we generally aim for 4-8 weeks. We maintain strategic stock for some common sizes to expedite urgent requirements.
Q7: How do you ensure the valve's quality meets marine standards?
A: Our ISO9001 quality management system governs every production stage. We perform rigorous tests, including shell tests, seat leak tests (according to API 598 or equivalent), and material verification. For critical orders, third-party inspection can be accommodated.
Q8: Can this valve be used for other applications besides FPSO?
A: Yes. While optimized for FPSO conditions, this high-performance forged steel ball valve is also well-suited for other offshore platforms, shipbuilding, power plants, and industrial applications requiring durable, high-pressure ball valves with flanged connections.
