Zhibang Valve
As a professional manufacturer with a solid foundation since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our premium Marine Ball Valve engineered to the exacting DIN 3357 standard. Designed specifically for the harsh demands of saltwater and marine environments, this valve leverages the superior corrosion resistance of 316 stainless steel to ensure reliable, long-lasting performance in critical fluid control systems. Our commitment to ISO9001-certified quality management guarantees that every valve meets stringent international standards, providing our global clientele in regions like North America, Southeast Asia, and Europe with a dependable solution they can trust.
This valve is built to withstand the corrosive challenges posed by seawater, brine, and other aggressive media commonly found in offshore platforms, shipbuilding, desalination plants, and coastal processing facilities. Its robust construction and precise engineering translate into minimal maintenance requirements, reduced downtime, and enhanced operational safety for your projects.
Key Features & Technical Advantages:
- Superior Corrosion Resistance: The body and ball are crafted from 316 stainless steel, which contains molybdenum, offering exceptional resistance to pitting and crevice corrosion in chloride-laden environments like seawater.
- DIN 3357 Compliance: Manufactured in strict adherence to the DIN 3357 standard for flanged ball valves, ensuring dimensional accuracy, interchangeability, and compatibility with European piping systems.
- Reliable Sealing Performance: Features PTFE (Polytetrafluoroethylene) seats, providing excellent chemical resistance, a wide temperature range tolerance, and bubble-tight shut-off to prevent leaks.
- Full Port Design: Offers minimal flow restriction and pressure drop, allowing for efficient fluid transfer and easier pipeline cleaning (pigging).
- Robust Operation: Equipped with a sturdy lever handle for quick and easy 90-degree quarter-turn operation, providing clear visual indication of the valve position (open/closed).
- Versatile Pressure Ratings: Available in common pressure classes such as PN16 and PN25 to suit various system requirements.
- Extended Service Life: The combination of high-grade materials and precision machining results in a durable valve capable of withstanding cyclic loading and harsh service conditions.

Frequently Asked Questions (FAQ)
-
What is the main advantage of using 316 stainless steel over 304 for this marine valve?
316 stainless steel contains molybdenum (2-3%), which significantly enhances its resistance to corrosion from chlorides, making it far more suitable for saltwater, seawater, and other aggressive chemical environments compared to 304 stainless steel. -
Is this valve suitable for underwater applications or constant immersion?
While designed for excellent corrosion resistance in marine environments, its suitability for permanent submersion depends on specific conditions like depth, water chemistry, and cathodic protection. We recommend consulting our engineers for such specialized applications. -
Can this DIN 3357 valve be connected to ANSI standard flanges?
The flanges are manufactured to DIN dimensions. For connection to ANSI piping systems, adapter flanges or specific custom orders would be required. Please inquire about your specific flange standard needs. -
What are the available actuation options beyond the manual lever handle?
We offer a range of actuation solutions, including pneumatic actuators, electric actuators, and gear operators. These can be customized and fitted to the valve based on your automation requirements. -
What is the typical delivery lead time for standard sizes?
For standard sizes and specifications, we generally maintain stock or have short production cycles. Lead times can vary; please contact us with your desired size and quantity for an accurate delivery schedule. -
Do you provide any documentation or certification with the valves?
Yes. Along with our company's ISO9001 certificate, we can provide material test reports (MTRs) and product inspection reports upon request to support your project documentation needs. -
Is the PTFE seat material suitable for high-temperature seawater applications?
The standard PTFE seat is rated for temperatures up to 150°C. For applications involving higher temperatures, alternative seat materials like PPL or metal-seated designs can be explored as custom options. -
How do I determine the correct pressure rating (PN) for my application?
The required pressure rating depends on your system's maximum working pressure and design standards. Our technical team can assist you in selecting the appropriate PN16 or PN25 rating, or a customized higher rating if needed.
