As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to introduce our high-performance DIN 3357 Electric Marine Ball Valve. Engineered specifically for demanding marine and offshore applications, this valve combines the superior corrosion resistance of 316 stainless steel with a robust IP68 waterproof electric actuator, ensuring reliable operation in the harshest environments. Our commitment to quality and precision manufacturing since 2016 guarantees a product that meets the stringent requirements of global markets, from North America and Europe to Southeast Asia and Oceania.
This electric marine ball valve is designed for seamless integration into automated fluid control systems onboard vessels, offshore platforms, and coastal infrastructure. The core of its durability lies in the 316 stainless steel construction, which offers exceptional resistance to pitting and crevice corrosion caused by chlorides in seawater. The electric actuator is housed in a sealed enclosure rated IP68, meaning it is dust-tight and can withstand continuous immersion in water under specified conditions, providing peace of mind for submersible or splash-zone applications.
Key Technical Specifications & Advantages:
- Superior Material Performance: The valve body, ball, and stem are crafted from 316 stainless steel, ensuring long service life even when handling corrosive media like seawater, bilge water, or chemical solutions.
- Uncompromising Sealing: High-quality seat materials (such as PTFE or reinforced polymers) are employed to achieve bubble-tight shut-off, minimizing leakage and enhancing system safety.
- Reliable Electric Actuation: The actuator provides precise quarter-turn operation (90° rotation) for open/close control. It can be equipped with feedback signals (open/close limit switches) and is compatible with various control systems (PLC, DCS).
- Robust Design Standards: Manufactured according to DIN 3357 standards for flanged ball valves, ensuring dimensional compatibility and interchangeability with other DIN-standard piping components.
- Versatile Configuration: Available in 2-way and 3-way port configurations. The electric actuator options include different voltages (e.g., 24V DC, 110V AC, 220V AC) and duty cycles (continuous or intermittent) to match specific project requirements.
- Ease of Maintenance: The design often allows for in-line maintenance, and the actuator can be easily detached without removing the valve from the pipeline, reducing downtime.

Frequently Asked Questions (FAQ)
-
Q: What does the IP68 rating mean for this electric actuator?
A: The IP68 rating signifies that the actuator enclosure is completely dust-tight (first digit '6') and can withstand continuous immersion in water beyond 1 meter depth, as specified by the manufacturer (second digit '8'). This makes it suitable for submerged applications or areas with constant water exposure. -
Q: Can this valve handle seawater directly?
A: Yes, the 316 stainless steel construction provides excellent resistance to chloride-induced corrosion, making it a preferred material for handling seawater, brine, and other corrosive marine media. -
Q: Are different voltage options available for the electric actuator?
A: Absolutely. We offer a range of standard voltage options such as 24V DC, 110V AC, and 220V AC. Custom voltages can also be accommodated upon request to match your shipboard or platform power supply. -
Q: Is the valve suitable for both on/off and flow control applications?
A: The standard version is designed for on/off service. However, we can provide actuators with proportional control (e.g., 4-20mA input for modulating flow) as an optional feature for applications requiring flow regulation. -
Q: What is the lead time for an order?
A: Lead times vary based on order quantity, valve size, and specific configuration. For standard models, it is typically shorter. We provide accurate lead time estimates upon receipt of your detailed specifications. -
Q: Do you provide certifications or test reports with the valves?
A> As an ISO9001 certified manufacturer, we conduct rigorous factory tests. Standard test reports (like pressure tests) can be provided. Specific marine certifications (like DNV-GL, ABS) may be available upon request and may involve additional cost and time. -
Q: How do I determine the correct valve size (DN) for my pipeline?
A> The valve size should match the nominal diameter (DN) of your connecting pipeline. Please provide your pipeline size and pressure rating, and our technical team can assist in selecting the appropriate model from the DIN 3357 series. -
Q: Can the actuator be manually overridden in case of a power failure?
A> Yes, most of our electric actuators come equipped with a manual override feature (handwheel or lever), allowing manual operation during power loss or for maintenance purposes.
