As a leading manufacturer in the valve industry, Shanghai Zhibang Valve is proud to present our premium CB/T3191 Cast Steel Marine Ball Valve. Engineered for the demanding environments of maritime and offshore applications, this valve combines robust construction with reliable performance. Our commitment to quality is backed by an extended warranty, offering you unparalleled peace of mind and long-term operational security for your critical piping systems.
This valve is specifically designed to handle seawater, ballast, fuel oil, and other marine fluids with exceptional durability. We understand that downtime is not an option in marine operations, which is why our product is built to last, ensuring smooth and safe control of fluid flow on vessels, rigs, and port facilities worldwide.
Key Features and Technical Advantages:
- Robust Cast Steel Body: Manufactured from high-grade cast steel (A216 WCB standard, with stainless steel options like A351 CF8/CF8M available), the valve body offers superior strength and excellent resistance to corrosion, particularly in saline and harsh offshore environments.
- Extended Warranty Assurance: Our confidence in product quality and longevity is demonstrated through an extended warranty program, significantly reducing your total cost of ownership and mitigating long-term maintenance risks.
- Full Bore & Reduced Bore Designs: Available in both full bore (full port) for minimal pressure drop and reduced bore (standard port) designs to suit different flow requirements and system pressures.
- Advanced Sealing Technology: Features resilient seats made from materials like PTFE or reinforced PTFE, providing bubble-tight sealing, low operating torque, and excellent chemical resistance. Metal-seated versions are available for high-temperature or abrasive service.
- Versatile Actuation Options: Can be equipped with manual levers, gear operators for larger sizes, or automated actuators (pneumatic/electric) for remote control and integration into ship automation systems.
- Fire-Safe Design (Optional): Available with fire-safe features in compliance with API 607, API 6FA, or ISO 10497 standards, ensuring secondary sealing in case of fire—a critical safety requirement for many marine applications.
- Anti-Static & Blow-Out Proof Stem: The stem is designed to prevent static electricity buildup and is securely locked to prevent ejection under pressure, enhancing operational safety.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of the CB/T3191 standard for marine valves?
A: The CB/T3191 is a Chinese national standard specifically for marine valves, outlining design, material, and testing requirements suitable for shipboard conditions. Valves built to this standard are recognized for their suitability in marine applications. -
Q: What does the "extended warranty" specifically cover?
A: Our extended warranty covers defects in materials and workmanship under normal service conditions for a period longer than standard industry offerings. Specific terms (duration, coverage) are provided with the commercial offer and are contingent on proper installation and operation. -
Q: Can this valve be used with seawater?
A: Yes, it is designed for seawater service. We recommend specifying appropriate material grades (such as CF8M stainless steel for wetted parts) and seat materials to ensure optimal corrosion resistance for long-term seawater exposure. -
Q: Are these valves suitable for high-pressure fuel oil lines on ships?
A: Absolutely. The cast steel construction and availability in Class 300 pressure rating make them suitable for fuel oil, lube oil, and other hydrocarbon services. Fire-safe design options are highly recommended for such applications. -
Q: Do you provide actuators for automated operation?
A: Yes, we can supply the valve as a complete package with pneumatic, electric, or hydraulic actuators. The specific actuator model will be selected based on your required torque, power supply, and control signal. -
Q: What is the typical delivery time for an order?
A: Delivery time depends on the order quantity, size, and material specifications. Standard configurations typically have shorter lead times. We provide estimated schedules upon order confirmation and leverage our port access for efficient logistics. -
Q: Can you provide valves with certifications from specific classification societies?
A> We can arrange for third-party inspection and certification from major marine classification societies (such as ABS, DNV, LR, BV, etc.) upon request. This may involve additional testing and documentation, which we can facilitate. -
Q: What is the difference between full bore and reduced bore in this context?
A: A full bore valve has an internal bore diameter equal to the connecting pipeline, minimizing flow resistance and pressure drop. A reduced bore valve has a smaller bore, which is often sufficient for many applications and can be a cost-effective choice where pressure drop is not a primary concern.
