Welcome to Shanghai Zhibang Valve Manufacture Co., Ltd., a professional manufacturer established in 2016 specializing in high-performance industrial valves. We proudly present our DIN 3357 Marine Ball Valve, engineered and produced in our own facility to deliver exceptional reliability for demanding maritime and offshore applications. Our direct-factory model ensures you receive not only a competitively priced, high-quality product but also comprehensive technical support from design to installation. With an annual export value between US$1 million and US$1.5 million and a presence in markets across North America, South America, Europe, Asia, Africa, and Oceania, we have built a reputation for supplying durable valves that meet the rigorous standards of the global marine industry. This valve is designed to provide a secure, long-lasting sealing solution for critical shipboard systems.
Our DIN 3357 Marine Ball Valve is constructed to withstand the harsh conditions of marine environments, including saltwater corrosion, high pressure, and constant vibration. The robust flanged connection ensures a leak-proof fit with piping systems, while the full-port design minimizes pressure drop for efficient fluid flow. We utilize high-grade materials and precision machining to guarantee every valve performs reliably over its extended service life.
Key Features & Technical Advantages:
- Robust Construction: Manufactured from materials like carbon steel with anti-corrosion coatings or stainless steel (304/316/316L) to resist saltwater corrosion and extend service life in marine settings.
- Superior Sealing: Features advanced seat materials such as PTFE or reinforced PTFE, which provide a bubble-tight seal and low operating torque, even after numerous cycles.
- Easy Operation & Maintenance: The quarter-turn operation allows for quick open/close control. A standardized design facilitates easy maintenance and part replacement, minimizing vessel downtime.
- Versatile Actuation Options: Available with manual lever handles, gear operators for larger sizes, or automated actuation (pneumatic/electric) for integration into remote control systems.
- Wide Application Range: Suitable for various shipboard services including bilge and ballast systems, fuel oil lines, cooling water systems, compressed air lines, and general service on tankers, cargo ships, and offshore platforms.

Frequently Asked Questions (FAQ)
Q1: What does "DIN 3357" refer to in your ball valve?
A1: DIN 3357 is a German industrial standard that specifies the design, dimensions, pressure ratings, and testing requirements for flanged ball valves. Valves manufactured to this standard ensure interchangeability, reliability, and compliance with many European and international marine project specifications.
Q2: Are your marine ball valves suitable for seawater applications?
A2: Yes, they are specifically designed for marine environments. We offer body materials like 316 stainless steel or coated carbon steel, along with corrosion-resistant trim, to provide excellent resistance to saltwater corrosion.
Q3: Can I get valves with different end connections, like ANSI flanges?
A3> Our standard offering is DIN flanges. However, as a manufacturer, we can provide customized valves with ANSI, JIS, or other flange standards upon request. Please inquire with your specific connection requirements.
Q4: What is the lead time for an order?
A4: Lead time depends on the order quantity, size, material, and actuation type. Standard configurations typically have shorter lead times. We provide an estimated timeline upon receipt of your detailed inquiry and can often accommodate urgent project needs.
Q5: Do you provide actuated valves (pneumatic/electric)?
A5: Yes. We can equip our DIN 3357 ball valves with pneumatic actuators, electric actuators, or gear operators based on your system's automation requirements. We assist in selecting the appropriate actuator type and specifications.
Q6: What documentation comes with the valves?
A6> Standard documentation includes a material test certificate (3.1 per EN 10204), product manual, and packing list. Additional certificates, such as NDT reports or fire-safe test certificates, can be provided as needed.
Q7: How do you ensure quality control?
A7> Our ISO9001 quality management system governs all processes. We perform material inspections, dimensional checks, pressure tests (shell & seat), and visual inspections on every valve before shipment to ensure it meets specified standards.
Q8: What are your main shipping ports?
A8> We primarily ship from Shanghai, Guangzhou, Hong Kong, and Beijing ports, offering flexibility to optimize logistics and cost for our customers worldwide.
