As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing reliable and high-performance fluid control solutions for demanding industrial and marine applications. Our DN80 CB/T3191 Electric Ball Valve is engineered specifically for marine environments, offering robust construction, precise control, and exceptional durability under PN16 pressure conditions. This valve combines the simplicity of a two-wire control system with the stringent requirements of maritime standards, delivering a dependable solution for shipboard piping systems where safety and reliability are paramount.
Designed for integration into complex marine control networks, this electric ball valve provides a compact and efficient method for remote on/off fluid flow control. Its construction adheres to the CB/T3191 standard, ensuring compatibility and performance within Chinese marine engineering specifications. For global buyers across our main markets from North America and Europe to Southeast Asia and Africa, this product represents a cost-effective and trustworthy component for ballast, cooling, fuel, and other critical ship systems.
Core Product Features & Technical Advantages:
- Marine-Grade Durability: The valve body, ball, and stem are manufactured from materials such as cast steel or stainless steel, selected for superior corrosion resistance against seawater and harsh marine atmospheres. Seals are compatible with a wide range of media including seawater, fresh water, oils, and air.
- Simplified Two-Wire Control: The integrated electric actuator operates on a straightforward two-wire connection for open/close commands, significantly simplifying installation, wiring, and integration with existing shipboard control panels or PLC systems compared to more complex multi-wire setups.
- High Pressure Integrity: Rated for PN16 (16 bar) pressure, this valve maintains a tight seal and reliable operation under the high-pressure conditions commonly found in marine piping systems, ensuring system safety and preventing leaks.
- Flanged Connection Compatibility: Features standard flanged ends as per CB/T3191, facilitating secure and leak-proof connection to DN80 piping networks, which is a common requirement in marine engineering for maintainability and strength.
- Compact & Space-Saving Design: The integrated design of the ball valve and electric actuator offers a compact footprint, an essential consideration in the space-constrained environments onboard vessels.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of a two-wire control system for this electric ball valve?
A: The two-wire system offers significant simplicity. It requires only a pair of wires to send an open or close signal, drastically reducing installation complexity, potential wiring errors, and costs compared to three-wire or network-based controls, which is highly valued in marine retrofit projects. -
Q: Is this DN80 Electric Ball Valve suitable for seawater service?
A: Yes, when configured with appropriate body materials like stainless steel (CF8/CF8M) and compatible seals, this valve is designed to handle seawater and other corrosive media typical in marine environments. Specific material selection should be confirmed based on your exact service conditions. -
Q: Can the valve be supplied with different voltage actuators?
A: Absolutely. We understand vessels have diverse electrical systems. The actuator can be customized for common voltages including 24VDC (for control panels), 110VAC, and 220VAC. Please specify your requirement when inquiring. -
Q: Does the valve come with any position feedback signal?
A: The standard two-wire on/off version provides basic open/close control. However, optional versions with auxiliary switches for open/close position indication (feedback) are available upon request for integration into monitoring systems. -
Q: What is the typical lead time for this product?
A: For standard configurations, we maintain efficient production schedules. Lead times are generally competitive and can be provided upon receipt of a detailed inquiry. Our multiple shipment ports (Shanghai, Guangzhou, Hong Kong, Beijing) allow for flexible logistics planning. -
Q: How does the CB/T3191 standard relate to other international marine standards?
A: CB/T3191 is a Chinese professional standard for shipbuilding valves. It specifies requirements for design, materials, testing, and marking. Valves manufactured to this standard are widely accepted in marine projects, especially in markets across Asia and by international shipyards familiar with these specifications. -
