As a leading manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our DIN 3357 Full Bore Marine Ball Valve. Established in 2016, we have dedicated ourselves to engineering robust fluid control solutions for demanding global markets. This valve is specifically designed to meet the rigorous standards of marine and offshore applications, where performance under pressure is non-negotiable. We understand that our clients in sectors like shipping, oil & gas, and coastal infrastructure require components that offer not just functionality but also complete traceability and peace of mind, which is why every valve is supplied with a comprehensive Mill Test Report.
Our full bore design is a key feature, providing minimal pressure drop and allowing for the efficient passage of fluids, which is critical for maintaining system efficiency and reducing pumping costs. The valve construction adheres strictly to the DIN 3357 standard, ensuring dimensional interchangeability and reliable performance in a wide range of industrial settings beyond marine use.
Key Product Features and Technical Advantages:
- Superior Flow Capacity: The full port design ensures an unrestricted flow path, virtually eliminating flow resistance and pressure loss, which is ideal for applications requiring pigging or where high flow rates are essential.
- Robust Construction for Harsh Environments: Manufactured from high-grade materials such as carbon steel (WCB), stainless steel (CF8/CF8M), and duplex stainless steel, these valves offer excellent resistance to corrosion, erosion, and the challenging conditions found in marine atmospheres and seawater systems.
- Reliable Sealing and Long Service Life: Featuring advanced seat materials like reinforced PTFE or metal seats, the valve ensures bubble-tight shut-off and extended durability, even after numerous cycles. The stem is designed with an anti-blowout feature for enhanced safety.
- Versatile Operation and Configuration: Available with manual lever, gearbox, or automated actuation (pneumatic/electric), providing flexibility for remote or automated control systems. Valves can be configured as standard floating ball or trunnion mounted for higher pressure classes.
- Comprehensive Quality Documentation: Each valve is accompanied by a Mill Test Report (MTR) that details the chemical composition and mechanical properties of the materials used, providing full traceability and verification of material quality.

Frequently Asked Questions (FAQ):
-
Q: What is the significance of the "Full Bore" design in this ball valve?
A: A full bore (or full port) valve has an internal bore diameter approximately equal to the pipeline's inner diameter. This design minimizes flow restriction and pressure drop, allows for pipeline pigging, and is optimal for applications requiring high flow capacity or handling viscous fluids. -
Q: Does the DIN 3357 standard make this valve suitable only for the European market?
A: Not at all. While DIN is a German standard, it is widely recognized and accepted globally for its precision and reliability. The dimensions are often compatible with other international standards, making these valves suitable for projects worldwide, especially where European specifications are referenced. -
Q: What exactly is included in the Mill Test Report (MTR)?
A: The MTR is a certified document from the material mill. It typically includes the heat number, chemical analysis, mechanical properties (yield strength, tensile strength, elongation), and results of any supplementary tests like impact tests, providing verifiable proof of the material's grade and quality. -
Q: Can this valve be used for services other than seawater?
A: Absolutely. Depending on the selected body and seat materials, this valve is highly versatile. It can handle a wide range of media including fresh water, oils, gases, steam, and various chemical fluids in industrial processing, making it a multi-purpose solution. -
Q: Are automated actuators available for these valves?
A: Yes. We offer a range of actuation options. The valves can be fitted with pneumatic (double-acting or spring-return) or electric actuators upon request. We can provide the complete assembled unit ready for installation. -
Q: What are the available pressure classes and how do I choose the right one?
A> Common pressure ratings are PN16, PN25, PN40 (metric) and Class 150, Class 300 (imperial). The selection depends on your system's maximum working pressure and design code. Our technical team can assist you in choosing the appropriate rating based on your application parameters. -
Q: Is the valve fire-safe certified?
A> Fire-safe design is an optional feature. We can supply valves that meet the requirements of standards like API 607 or API 6FA, which include secondary metal sealing to provide a leak-resistant barrier in the event of a fire, upon customer request. -
Q: What is your typical lead time for orders?
A> Lead times vary based on order quantity, size, material, and configuration. Standard specifications are often available from stock or have shorter production cycles. We provide accurate delivery estimates upon receipt of your detailed inquiry to ensure we meet your project timeline.
