As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance marine valves engineered for demanding applications. Our CB/T3191 Marine Ball Valve is specifically designed for high-pressure fuel systems, offering reliable shut-off and control in critical shipboard environments. Built to withstand the rigorous conditions of marine operations, this valve ensures safe and efficient fuel management from bunkering to engine supply lines.

We understand that valve failure in fuel systems is not an option, which is why we employ stringent quality control processes in our manufacturing. With an annual export value reflecting our global reach, our valves are trusted by shipyards and vessel operators across multiple continents. The CB/T3191 series represents our commitment to providing durable, leak-proof solutions that meet international marine standards.

Key Product Features & Technical Advantages:

Robust Construction for Marine Duty: Engineered with materials selected for corrosion resistance in saltwater environments. The valve body is typically manufactured from stainless steel (CF8M/316SS) or carbon steel with appropriate coatings to prevent degradation from marine atmospheres and fuel contaminants.
High-Pressure Integrity: Designed to handle the elevated pressures found in modern marine fuel systems, including those for heavy fuel oil (HFO), marine diesel oil (MDO), and marine gas oil (MGO). The reinforced seat design and precision-machined ball ensure a bubble-tight seal even after prolonged cycling.
Fire-Safe Design Considerations: While specific fire-safe certification should be confirmed per project requirements, the design incorporates features such as secondary metal sealing that can provide a seal in the event of soft seat damage from high temperatures.
Full Port or Reduced Port Options: Available in full bore design to minimize pressure drop across the valve, which is crucial for fuel supply efficiency, or standard port for applications where space and weight are primary concerns.
Versatile End Connections: Configured with flanged ends (ISO, ANSI, JIS standards), threaded (NPT, BSP), or butt-weld ends to seamlessly integrate into existing ship piping systems from DN10 to DN50.
Multiple Actuation Methods: Can be supplied with a manual lever, a gear operator for larger sizes or higher torque requirements, or automated with pneumatic or electric actuators for remote control and integration into vessel automation systems.
Low Maintenance & Easy Operation: The simple quarter-turn operation allows for quick open/close functions. Stem seal designs are accessible for potential maintenance without requiring valve removal from the line.

Benefits for Your Marine Operations:

Enhanced System Safety: Reliable shut-off prevents fuel leaks, protecting personnel, machinery, and the marine environment. The robust design minimizes the risk of in-service failure.
Reduced Lifetime Costs: The durability and low-maintenance design lead to lower total cost of ownership compared to valves requiring frequent repair or replacement.
Operational Efficiency: Quick quarter-turn operation and full-port design reduce flow resistance, contributing to efficient fuel transfer and system performance.
Global Compliance & Compatibility: Manufactured to the CB/T3191 standard, which is recognized in marine applications, and can be produced to meet other international standards upon request for global fleet compatibility.
Supply Chain Reliability: As a manufacturer, we control production from raw material to finished product, ensuring consistent quality and reliable lead times for shipyards and repair docks.

Frequently Asked Questions (FAQ):

Q: Is this valve suitable for both high-pressure fuel oil and diesel oil lines?
A: Yes, the CB/T3191 Marine Ball Valve is designed to handle various marine fuels, including MDO, MGO, and HFO, within its specified pressure and temperature ratings. Material selection (especially seat material) can be optimized based on the specific fuel type.
Q: Can you provide valves with specific face-to-face dimensions per ANSI or ISO standards?
A: Absolutely. While we manufacture to the CB/T3191 standard, we can produce valves with face-to-face dimensions compliant with common international standards like ANSI B16.10 or ISO 5752 upon request, ensuring easy replacement in existing piping.
Q: What documentation is provided with the valves?
A> Standard documentation includes a material test report (MTR) for the body material, a certificate of conformity, and operational manuals. Additional certifications, such as NDT reports or third-party inspection certificates, are available upon request.
Q: Are these valves suitable for cryogenic service or very high temperatures?
A: The standard temperature range is -20°C to +200°C. For cryogenic applications (e.g., LNG fuel systems) or sustained high-temperature services, special material grades and seat designs are available. Please consult with us for your specific temperature requirements.
Q: Do you offer anti-static and fire-safe versions?
A: Features like an anti-static device (to prevent sparking from static electricity) and fire-safe design with secondary metal seals are common options we can incorporate. Confirm your project specifications, and we will advise on the appropriate configuration.
Q: What is your lead time for an order of DN10-DN50 valves?
A: Lead time varies based on order quantity, material specification, and valve configuration. For standard materials and configurations, typical production lead time is 4-8 weeks. We provide firm lead times upon receipt of your detailed inquiry.
Q: Can the valves be fitted with actuators for automated control?
A: Yes, we can supply the valves as a complete package with pneumatic (double-acting or spring-return) or electric actuators. We ensure proper mounting and torque matching for reliable automated operation.
Q: How do you ensure quality control during manufacturing?
A> Our ISO9001 certified quality management system governs the entire process. This includes incoming material inspection, in-process checks during machining and assembly, and final testing (typically including shell test, seat test, and operational torque test) before shipment.
