Shanghai Zhibang Valve
As a specialized manufacturer with a strong presence in the global marine industry, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly offers its CB/T3191 Marine Ball Valve. Engineered to meet the rigorous demands of shipboard applications, this valve represents a reliable and efficient solution for controlling fluid flow in critical marine systems. Our commitment to ISO9001-certified quality and our extensive experience exporting to major markets worldwide ensure that you receive a product built for performance and longevity.
The core value of our marine ball valve lies in its robust construction and adherence to the specific CB/T3191 standard, which governs valves for marine use. This guarantees compatibility and reliability within the demanding marine environment, characterized by constant vibration, corrosive saltwater exposure, and stringent safety regulations. We understand that downtime is unacceptable at sea, which is why our valves are designed for durability and ease of maintenance.
Key Features and Technical Advantages:
- Standard-Compliant Design: Strictly manufactured according to the CB/T3191 standard for marine valves, ensuring regulatory compliance and interchangeability within shipbuilding specifications.
- Corrosion-Resistant Materials: Available in a range of materials including carbon steel with protective coatings, 304/316 stainless steel, and cast steel, providing optimal resistance to seawater, marine atmospheres, and various shipboard fluids (fuel, oil, ballast water, cooling systems).
- Robust Pressure Containment: Engineered for a wide spectrum of pressure classes, suitable for both low-pressure service lines and high-pressure hydraulic applications onboard.
- Versatile End Connections: Offered with flanged (RF, RTJ), threaded (NPT, BSP), or butt-weld ends to seamlessly integrate into existing marine piping systems.
- Reliable Sealing Performance: Utilizes advanced seat materials like PTFE or metal-seated designs to ensure bubble-tight shut-off, even after prolonged cycles, minimizing leakage risks.
- Multiple Actuation Options: From simple manual levers for accessible locations to gear operators for larger sizes, and pneumatic or hydraulic actuators for remote/automated control systems, providing flexibility for any ship design.
- Fire-Safe Design Available: Optional fire-safe construction per relevant standards (e.g., API 607, API 6FA) to maintain integrity in the event of a fire, a critical safety feature for marine applications.
- Low Maintenance & Easy Operation: The quarter-turn operation allows for quick open/close functions, and the streamlined design minimizes areas for debris accumulation, simplifying onboard maintenance.

Frequently Asked Questions (FAQ)
-
Q: What does "CB/T3191" mean, and why is it important for marine valves?
A: CB/T3191 is a Chinese national professional standard specifically for "Marine Valves." It defines the design, material, manufacturing, testing, and inspection requirements for valves used in shipbuilding and offshore industries. Using a valve compliant with this standard ensures it meets the specific safety, performance, and environmental demands of marine applications. -
Q: Can this marine ball valve be used for both seawater and fuel/oil lines?
A: Yes, but material selection is crucial. For seawater services, we typically recommend 316 stainless steel or superior alloys for optimal corrosion resistance. For fuel and oil lines, carbon steel with appropriate coatings or other specified materials can be suitable. Our technical team can advise based on your specific fluid media. -
Q: Do you offer actuators for remote valve operation?
A: Absolutely. We provide a range of actuation solutions. Pneumatic and hydraulic actuators are available for integration into automated control systems, which are common in modern vessel engine rooms and cargo handling systems. -
Q: What is the typical lead time for an order?
A: Lead times vary based on valve size, material, actuation requirements, and order quantity. Standard configurations often have shorter lead times. We provide accurate delivery estimates upon receipt of your detailed inquiry to ensure it aligns with your project schedule. -
Q: How do you ensure quality control?
A: Our manufacturing processes are certified under the ISO9001 Quality Management System. This encompasses strict control from raw material procurement to machining, assembly, pressure testing, and final inspection. Every valve undergoes hydrostatic shell and seat tests to verify its pressure integrity. -
Q: Can you provide valves with specific certifications required by classification societies?
A: While we hold ISO9001, specific certifications from marine classification societies (like ABS, DNV, LR, BV, etc.) can be arranged upon request. Please specify your certification requirements during inquiry so we can confirm feasibility. -
Q: What after-sales support do you offer?
A: We provide comprehensive technical support, including installation manuals, maintenance guidelines, and spare parts availability. Our "Technical Support Available" promise means our engineers are ready to assist with any technical queries during and after installation. -
Q: What are your main export markets, and do you have experience with international shipping?
A: We have extensive export experience, serving markets across North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East. We handle logistics from major Chinese ports and are proficient in export documentation, ensuring smooth delivery to your destination.
