As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance industrial valves for demanding global markets. Our DIN 3357 Marine Ball Valve is engineered specifically for the rigorous conditions of offshore platform piping applications. With an annual export value demonstrating our global reach, we combine precision manufacturing with an understanding of marine and offshore requirements to deliver valves that ensure reliability, safety, and long-term performance in critical fluid handling systems.
This valve is designed to meet the exacting standards of offshore oil & gas, marine, and coastal industrial facilities where corrosion resistance, pressure integrity, and dependable shut-off are non-negotiable.
Key Features & Technical Advantages:
- Robust Construction for Marine Environments: Manufactured from materials selected for superior corrosion resistance, such as carbon steel with protective coatings, stainless steel (CF8/CF8M), or duplex/super duplex steels. The design effectively withstands saline atmospheres, seawater spray, and other corrosive elements prevalent offshore.
- DIN 3357 Standard Compliance: Conforms to the DIN 3357 standard for flanged ball valves, ensuring dimensional interchangeability, reliable performance metrics, and compatibility with European piping specifications commonly used in offshore projects.
- High-Pressure & Temperature Capability: Engineered for a wide range of operating conditions typical of platform piping.
| Parameter | Specification |
|---|---|
| Pressure Rating (PN) | PN10, PN16, PN25, PN40 |
| Size Range (DN) | DN15 (1/2") to DN300 (12") |
| Temperature Range | Standard: -20°C to +150°C (with PTFE seats) Extended: Up to +180°C or lower cryogenic ranges (configurable) |
| Seat Materials | Standard PTFE, Reinforced PTFE (RPTFE), PEEK, Metal Seated (for high temp/fire-safe) |
| End Connection | Flanged per DIN EN 1092-2 (PN) / ASME B16.5 (Class) optionally available |
| Fire Safe Design | Optional compliance with API 607/API 6FA standards |
| Leakage Class | Standard: ANSI/FCI 70-2 Class IV Bidirectional: Optional Class VI (bubble-tight) |
- Superior Sealing Performance: Utilizes advanced seat designs and materials like PTFE or reinforced polymers to ensure bubble-tight shut-off (optional Class VI leakage), minimizing product loss and environmental risk.
- Versatile Actuation Options: Available with manual lever handles, gear operators for larger sizes, or can be fitted with pneumatic, hydraulic, or electric actuators for remote or automated control, integrating seamlessly into platform SCADA systems.
- Low Maintenance & Easy Operation: The quarter-turn design allows for quick open/close function. A self-compensating seat design and blow-out-proof stem enhance safety and reduce the need for frequent maintenance, a crucial factor for hard-to-access offshore locations.
- Broad Application Scope: Specifically designed for offshore platform services but equally suitable for various demanding applications.
Benefits for Your Offshore Operations:
- Enhanced System Reliability: Reduces unplanned downtime due to valve failure, which is critical for continuous offshore production.
- Improved Safety: Reliable shut-off capability contributes to overall platform safety, preventing leaks in process lines, utility services (water, air), and hydrocarbon systems.
- Cost-Effective Lifecycle: Durable materials and design lead to a longer service life and lower total cost of ownership, offsetting the higher initial investment compared to standard valves.
- Global Supply & Support: With main markets across North America, South America, Europe, Asia, Africa, and Oceania, and major shipment ports like Shanghai, Guangzhou, and Hong Kong, we ensure timely delivery and logistical support for international projects.
Backed by our experience since 2016 and ISO9001-certified manufacturing processes, our DIN 3357 Marine Ball Valve represents a reliable component choice for engineering contractors and platform operators.

Frequently Asked Questions (FAQ)
Q1: What does "DIN 3357" specify for this ball valve?
A1: DIN 3357 is a German industrial standard that defines the design, dimensions, pressure-temperature ratings, and testing requirements for flanged ball valves. Compliance ensures the valve meets recognized European engineering norms for performance and interchangeability, which is often required in international offshore projects.
Q2: Can this valve be used with seawater directly?
A2: Yes, but material selection is critical. For direct seawater service, we recommend specifying body materials like Super Duplex Stainless Steel (UNS S32750) or 6Mo Austenitic Stainless Steel, along with compatible seat materials, to prevent chloride-induced corrosion and ensure long-term integrity.
Q3: Is a fire-safe version available?
A3: Yes, a fire-safe design is an optional feature. Valves can be manufactured with secondary metal seats and other features to comply with API 607 or API 6FA standards, providing a seal in the event of a fire when polymer seats may degrade.
Q4: What actuation methods do you support?
A4: We provide flexibility. The valve can be supplied as a manual valve (lever or gearbox) or prepared for actuator mounting. We can source and pre-assemble pneumatic (double-acting or spring-return), hydraulic, or electric actuators from reputable brands or as per your specifications.
Q5: What is your lead time for OEM orders?
A5: Lead times vary based on order quantity, material specifications, and special requirements (like fire-safe or special testing). Standard configurations typically have a shorter lead time. We provide estimated timelines upon receipt of your detailed inquiry and work to meet project schedules.
Q6: Do you provide documentation like test reports and material certificates?
A6: Yes, as an ISO9001-certified manufacturer, we provide essential documentation including material test certificates (MTC/CMTR), pressure test reports (shell & seat tests), and a full inspection report. Additional certifications like NACE MR0175/ISO 15156 for sour service are available upon request.
Q7: How does this valve compare to API 6D or ASME B16.34 valves?
A7: DIN 3357 valves are broadly equivalent in performance to valves designed per API 6D or ASME B16.34 but follow European dimensional and design conventions. The core difference often lies in flange dimensions (DIN vs. ASME) and some testing protocols. We can advise on the most suitable standard for your specific project requirements.
Q8: Can you customize the valve trim or provide special coatings?
A8: Absolutely. We offer OEM services and can customize seat/ball materials, stem packing, and apply special internal/external coatings like epoxy, Xylan, or galvanizing for additional corrosion protection. Please share your specific service conditions for a tailored recommendation.
