As a professional manufacturer of industrial valves with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance Ball Valve for Marine Engine Room Fuel Oil Piping. Engineered specifically to meet the rigorous demands of maritime applications, this valve is manufactured in strict compliance with the CB/T3191 standard and features robust flanged ends for secure and reliable installation. With our extensive experience since 2016 and a strong export presence across global markets including North America, Europe, and Southeast Asia, we deliver valves that ensure safety, durability, and optimal flow control in critical marine fuel systems.
This marine ball valve is designed to provide exceptional service in the challenging environment of a ship's engine room. Its construction focuses on leak-proof operation and long-term reliability under constant vibration and corrosive conditions.
- Robust Construction: The valve body is crafted from high-grade materials such as carbon steel or stainless steel, selected for their excellent strength and corrosion resistance against marine fuel oils.
- Precision Sealing: Features advanced seat materials like PTFE, ensuring a tight seal and minimal fugitive emissions, which is critical for environmental compliance and onboard safety.
- Standard Flanged Ends: The flanged design per CB/T3191 facilitates easy alignment, bolting, and integration into existing fuel oil piping networks, reducing installation time and labor costs.
- Smooth Operation: The quarter-turn ball mechanism allows for quick and easy open/close operation, even in confined engine room spaces, with options for lever handles or gear operators for higher torque applications.
- Versatile Configuration: Available in a range of sizes and pressure ratings to suit various system specifications, from auxiliary lines to main fuel supply lines.

Frequently Asked Questions (FAQ)
Q1: What does "per CB/T3191" mean for this ball valve?
A1: "CB/T3191" is a Chinese shipbuilding industry standard that specifies requirements for valves used in marine piping systems. Valves manufactured to this standard are designed and tested to meet the specific safety, material, and performance criteria demanded by the maritime environment, ensuring reliability and regulatory acceptance.
Q2: Are the flanges on this valve compatible with international flange standards like ANSI or DIN?
A2: While the valve is designed per CB/T3191, the flange dimensions and drilling can typically be manufactured to match common international standards such as ANSI B16.5 or DIN upon request. It is crucial to specify your required flange standard and pressure class when inquiring or ordering.
Q3: What material options are best for handling marine fuel oil (MGO, MDO, IFO)?
A3: For most marine fuel oils, carbon steel (WCB) bodies with stainless steel (SS316) trim offer a good balance of cost and corrosion resistance. For more aggressive environments or specific client specifications, full stainless steel (CF8M/SS316) construction is available. We can advise on the optimal material selection based on your fuel type and operating conditions.
Q4: Can this valve be supplied with an actuator for remote operation?
A4: Yes. While the standard configuration includes a manual lever or gear operator, we can integrate pneumatic (air) or electric actuators to enable remote and automated control of the valve. Please provide your required torque, power supply, and control signal details for a customized solution.
Q5: What is the lead time for standard sizes, and do you offer custom manufacturing?
A5: Lead times for standard sizes from our inventory are generally short. For custom specifications regarding size, pressure rating, material, or actuation, the lead time will vary based on complexity. Our manufacturing flexibility allows us to accommodate a wide range of custom requirements to fit your project timeline.
Q6: Do you provide documentation like material certificates and test reports?
A6> Yes. As an ISO9001 certified manufacturer, we can provide comprehensive documentation packages, which may include material chemical and mechanical test certificates, pressure test reports, and certificates of conformity. Specific documentation is available upon request.
Q7: What are the main shipping ports, and do you handle export formalities?
A7: We primarily ship from Shanghai, Guangzhou, Hong Kong, and Beijing ports. Our company has extensive experience in export procedures and can handle all necessary formalities, including customs clearance documentation, to ensure smooth delivery to your designated destination.
Q8: Is this valve suitable for other fluids besides fuel oil in marine applications?
A8: With appropriate material selection, this ball valve design can be suitable for other marine services such as lubricating oil, seawater (with suitable materials), bilge, and ballast systems. Please consult with our technical team to confirm suitability for your specific fluid media.
