As a leading manufacturer with a strong commitment to maritime fluid control solutions, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Electric Actuated Marine Ball Valve. Engineered to the rigorous CB/T3191 standard, this valve is designed for reliable performance in demanding marine and offshore environments. Our years of expertise since 2016 are embedded in this product, offering shipbuilders, system integrators, and marine engineers a robust and trustworthy solution for critical on-board piping systems. The combination of electric actuation, flanged connection, and an IP67-rated enclosure ensures seamless automation, easy installation, and superior protection against harsh elements.
This valve is built to excel where reliability is non-negotiable. The electric actuator provides precise and rapid open/close control, which is essential for automated systems on vessels. The flanged connection conforms to international standards, facilitating a secure and leak-proof integration into existing pipelines. The IP67 enclosure is a standout feature, offering complete protection against dust ingress and the effects of temporary immersion in water, making it suitable for decks, machinery spaces, and other challenging locations.
- Robust Construction & Compliance: Manufactured in adherence to the CB/T3191 standard for marine valves, ensuring material quality, pressure ratings, and dimensions meet specific maritime requirements.
- Superior Environmental Protection: The IP67 enclosure guarantees the actuator's functionality in wet, humid, and dusty conditions, significantly enhancing operational lifespan and reducing maintenance.
- Efficient Electric Actuation: Enables remote operation and integration into centralized control systems (DCS/SCADA), improving operational efficiency and safety by reducing manual intervention.
- Versatile Flanged Design: The flanged end connection ensures a strong, stable, and easily maintainable joint, compatible with a wide range of pipeline flanges.
- Wide Material Selection: Valve bodies are typically available in cast steel, stainless steel (304/316), and other alloys upon request to handle various media like seawater, fuel, oil, and air.
- Flexible Configuration: Available with different voltage inputs (AC/DC), control signals (on/off or modulating), and optional accessories like limit switches, positioners, and manual overrides.

Frequently Asked Questions (FAQ)
-
Q: Is this valve suitable for seawater service?
A: Yes, when ordered with appropriate body and trim materials such as 316 stainless steel or duplex steel, this valve is well-suited for handling seawater, ballast water, and other corrosive marine fluids. -
Q: Can the electric actuator be used for flow control (throttling)?
A: The standard actuator is configured for on/off (open/close) service. However, modulating actuators with proportional control (4-20mA input) are available as an option for precise flow regulation. -
Q: What is the meaning of the IP67 rating?
A: IP67 means the enclosure is completely protected against dust (6) and can withstand temporary immersion in water up to 1 meter for 30 minutes (7). This makes it ideal for washdown areas, decks, and engine rooms. -
Q: Do you provide actuators with manual override?
A: Yes, a manual handwheel or crank override is a common optional feature. This allows for manual operation in case of power failure or during maintenance. -
Q: Are the flanges compatible with international standards like ANSI or JIS?
A: While the valve is built to the CB/T3191 standard, the flange dimensions and facing can be manufactured to align with common international standards such as ANSI, DIN, or JIS upon request to ensure compatibility with your existing piping. -
Q: What is the typical lead time for an order?
A: Lead time depends on the specification, quantity, and customization. For standard configurations in moderate quantities, production typically takes 4-6 weeks. We provide accurate timelines upon order confirmation. -
Q: What kind of warranty do you offer?
A: We offer a standard warranty against manufacturing defects. The specific warranty period and terms are provided with the commercial contract and can vary based on the application. -
Q: Can you provide technical support for installation and integration?
A: Absolutely. Our technical team can provide installation manuals, wiring diagrams, and basic integration guidance. For complex system integration, detailed support is available upon request.
