As a specialized manufacturer with ISO9001 certification, Shanghai Zhibang Valve is proud to present our CB/T3191 Marine Electric Ball Valve with Remote Control. Engineered for demanding marine and offshore environments, this valve combines robust construction with intelligent automation, offering reliable fluid control for seawater, ballast, fuel, and other critical shipboard systems. With over seven years of industry experience and products exported globally, we understand the need for durability, safety, and precise control in maritime operations.
Core Product Features & Technical Advantages:
- Dual Power Compatibility: Designed for flexible integration, the valve actuator supports both 24V DC (standard shipboard power) and 220V AC power supplies, making it suitable for various vessel electrical systems.
- Advanced Remote Control: Enables centralized operation from the bridge or control room. It accepts switch signals or PLC/DCS commands for seamless automation within the ship's management system.
- Marine-Grade Construction: Manufactured in compliance with the CB/T3191 standard, the valve body is typically cast from corrosion-resistant materials like cast steel (WCB) or stainless steel (CF8/CF8M) to withstand saline atmospheres and seawater.
- High-Performance Sealing: Utilizes seats made from PTFE, EPDM, or Viton, ensuring tight shut-off, long service life, and compatibility with a wide range of media including water, oil, and mild chemicals.
- Rugged & Protected Actuator: The electric actuator is housed in an IP67-rated enclosure, providing excellent protection against water ingress, dust, and harsh weather conditions on deck or in engine rooms.
- Fail-Safe Options: Available with optional fail-safe (spring return) functions. The valve can be configured to open or close automatically upon power loss, enhancing system safety.
- Manual Override: Equipped with a manual handwheel or lever for local operation during maintenance, testing, or emergency power failure scenarios.
- Wide Size & Pressure Range: We offer a comprehensive range to meet diverse piping requirements.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of an electric ball valve over a manual one on a ship?
A: The primary advantage is the ability for remote and automated control. This allows operators to open or close valves from a central control room, improving efficiency, safety in hazardous areas, and enabling integration into automated ballast, fuel, or cooling water systems. -
Q: Can this valve be used with both freshwater and seawater systems?
A: Yes, absolutely. When ordered with appropriate body (e.g., stainless steel 316) and seal materials (e.g., EPDM or Viton), the valve is fully suitable for handling both freshwater and seawater, offering excellent corrosion resistance. -
Q: How do I choose between 24V DC and 220V AC power?
A: The choice depends on your vessel's available power supply at the valve location. 24V DC is common for control circuits and smaller vessels. 220V AC is standard for larger shipboard auxiliary power. Our valve can be configured for either, and we can advise based on your system drawings. -
Q: Is the actuator waterproof for deck mounting?
A: Yes, the standard actuator features an IP67 protection rating, meaning it is dust-tight and protected against temporary immersion in water. For permanent submersion or more extreme conditions, an IP68 option is available. -
Q: Do you provide valves with different end connections (flange types)?
A: Yes. While compliant with CB/T3191 dimensions, we can supply valves with various flange standards (e.g., JIS, DIN, ANSI) upon request to match your existing piping. -
Q: What is the lead time for production and delivery?
A: Lead time varies based on order quantity, size, and material specifications. Standard configurations typically have a shorter lead time. We provide clear timelines upon order confirmation and leverage our multiple port options for efficient shipping. -
Q: Can the valve be interfaced with our existing shipboard PLC system?
A: Certainly. The actuator accepts standard control signals like 4-20mA analog or dry contact signals from a PLC. Providing your interface requirements allows us to deliver a plug-and-play solution. -
Q: What after-sales support do you offer?
A: We provide comprehensive technical documentation, installation manuals, and responsive customer support. Spare parts for the actuator and valve are available to ensure long-term operability.
