As a leading manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in delivering high-performance industrial valves. Our DIN 3357 2205 Duplex Stainless Steel Ball Valve with a Full Port and Fire Safe Design represents our commitment to engineering excellence for critical applications. Engineered to withstand corrosive and high-pressure environments, this valve offers superior durability and reliable shut-off, making it an ideal solution for demanding sectors like oil & gas, chemical processing, and offshore operations.
This valve is meticulously crafted to meet the rigorous demands of modern industry. Below are its key features and technical specifications:
- Superior Corrosion Resistance: Constructed from Duplex Stainless Steel 2205 (UNS S31803/S32205), this valve offers excellent resistance to stress corrosion cracking, pitting, and crevice corrosion, especially in chloride-containing environments. Its balanced austenitic-ferritic microstructure provides double the yield strength of standard 316 stainless steel.
- Full Port (Full Bore) Design: The full port configuration ensures minimal pressure drop and turbulence, allowing for maximum flow capacity. This is crucial for applications requiring efficient fluid transfer and pigging operations in pipelines.
- Certified Fire Safe Design: The valve is designed and tested to meet recognized fire safety standards such as API 607, API 6FA, or ISO 10497. In the event of a fire, the primary soft seals may degrade, but the secondary metal-to-metal sealing mechanism engages to prevent catastrophic leakage, enhancing plant safety.
- Robust Construction & Standards Compliance: Manufactured according to DIN 3357 standards for flanged end ball valves, ensuring dimensional interchangeability and reliable performance. It is suitable for a wide range of pressure classes and can be customized to specific project requirements.
- Versatile Seating Options: Available with various seat materials like PTFE for standard service, reinforced PTFE for higher temperatures, or metal seats for abrasive services or extreme temperatures, providing flexibility for different operational needs.
- Low Maintenance & Easy Operation: The quarter-turn operation ensures quick and easy open/close function. The robust stem design with anti-blowout feature and high-quality sealing components reduces maintenance frequency and total cost of ownership.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of using Duplex 2205 over standard 316 stainless steel for this ball valve?
A: Duplex 2205 stainless steel offers approximately twice the yield strength and significantly better resistance to stress corrosion cracking and pitting, especially in chloride-rich environments like seawater or chemical processing. This translates to a longer service life and higher pressure capability in demanding applications. -
Q: How does the "Fire Safe" feature actually work in this valve?
A: In a fire-safe design, the primary soft seals (like PTFE) may melt or degrade under intense heat. However, the valve incorporates a secondary sealing system, typically involving metal-to-metal contact between the ball and seat. This secondary seal engages due to thermal expansion or spring loading, maintaining a seal and preventing major fluid leakage even after the primary seal fails. -
Q: What does "Full Port" or "Full Bore" mean, and when should I choose it?
A: A Full Port valve has an internal bore diameter essentially equal to the nominal pipe diameter. This minimizes flow restriction and pressure drop. It is recommended for applications requiring maximum flow, slurry services, or where pipeline pigging is necessary. For standard throttling or on/off service where minimal pressure drop is not critical, a reduced port valve could be a cost-effective alternative. -
Q: Can this DIN 3357 valve be connected to piping systems following ANSI/ASME standards?
A: Yes, it can be adapted. While the flange dimensions are per DIN/EN standards, adaptor flanges or specific configurations can be supplied to interface with ANSI/ASME B16.5 flanged systems. It's important to specify your piping standard when inquiring so we can provide the correct configuration. -
Q: What actuation options are available for this ball valve?
A: The valve can be operated manually with a lever or a geared handwheel for larger sizes. For automated control, it can be fitted with pneumatic (air), hydraulic, or electric actuators. We offer a range of actuator brands and types, which can be mounted and tested at our factory before shipment. -
Q: Is the fire-safe certification tested and documented?
A: Yes. Our fire-safe design is engineered to comply with the testing procedures outlined in standards like API 607, API 6FA, or ISO 10497. Relevant test reports or certificates from recognized laboratories can be provided upon request to support your safety documentation. -
Q: What is the typical lead time for an order of these valves?
A: Lead time depends on the order quantity, size, pressure rating, and any customization (like actuation). For standard configurations in common sizes, we often have stock or shorter production cycles. We provide accurate lead time estimates with every formal quotation. -
Q: Do you offer material test certificates for the Duplex 2205 steel used?
A: Absolutely. As a professional manufacturer, we can provide Mill Test Certificates (MTC) or Material Certificates (3.1 according to EN 10204) for the raw materials upon request, traceable to the specific production batch of your valves.
