As a specialized valve manufacturer with extensive experience in the marine industry, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to offer our high-performance Marine Ball Valves designed specifically for fuel oil service. Our valves are engineered to meet the rigorous demands of maritime applications, ensuring reliable flow control, tight shut-off, and long-term durability in harsh environments. We provide factory-direct pricing and comprehensive technical support, including complete dimensional drawings, to facilitate easy specification, procurement, and installation for shipyards, ship owners, and marine equipment suppliers worldwide. Our commitment to quality, backed by our ISO9001 certified manufacturing processes, ensures that every valve delivers consistent performance and safety.
Our Marine Ball Valves for fuel oil are constructed to handle the specific challenges of marine fuel systems, including the presence of heavy oils, potential for corrosion, and the critical need for operational reliability. The primary features and benefits of our valves include:
- Robust Construction: The valve body and ball are manufactured from high-grade materials such as carbon steel (WCB, LCB) or stainless steel (CF8, CF8M, CF3, CF3M) to withstand corrosion and mechanical stress. Critical components are precision-machined to ensure perfect alignment and smooth operation.
- Superior Sealing Performance: We utilize advanced seat materials like PTFE or reinforced PTFE, which provide excellent chemical resistance against fuel oils and ensure a bubble-tight seal, minimizing leakage and fugitive emissions.
- Compliance with Marine Standards: The valves are designed and manufactured in accordance with the Chinese CB/T3191 standard for marine valves, ensuring compatibility with marine piping systems. They can also be produced to meet other international standards such as ANSI, DIN, JIS, and GB upon request.
- Versatile Operation: Available with manual operation via a lever or gearbox for easy on/off control. For remote or automated systems, we offer options for pneumatic or electric actuators, providing flexibility for various shipboard control schemes.
- Enhanced Safety Features: Optional fire-safe design is available, incorporating features like anti-static devices and fire-resistant graphite seals to prevent ignition risks and maintain integrity in case of fire, meeting relevant safety regulations.
- Complete Documentation: A key differentiator is our provision of complete dimensional drawings (outline, face-to-face, flange dimensions) with every quotation and order. This transparency aids in seamless integration into your piping design and eliminates guesswork during installation.

Frequently Asked Questions (FAQ)
-
Q: What does "CB/T3191" mean in your product title?
A: CB/T3191 is a Chinese national professional standard specifically for "Marine Valves." It outlines the design, material, manufacturing, testing, and inspection requirements for valves used on ships. Our valves are produced to comply with this standard, ensuring they are fit for marine service. -
Q: Are your valves suitable for other fluids besides fuel oil?
A: Yes, while optimized for fuel oil, these ball valves can also be used for other marine services such as lubricating oil, seawater (with appropriate material selection like 316 stainless steel), compressed air, and inert gases. Please consult with us for your specific media. -
Q: Do you provide valves with different end connections?
A: Absolutely. We offer a variety of end connections including flanged (raised face, ring type joint), threaded (NPT, BSP), and butt weld ends to match your existing piping system specifications. -
Q: What is included in the "complete dimensional drawings" you provide?
A: Our comprehensive drawings typically include an outline general arrangement drawing showing overall dimensions, face-to-face dimensions as per relevant standards, detailed flange dimensions (bolt circle, bolt hole size), port sizes, and operator dimensions. These are essential for piping layout and integration. -
Q: Can these valves be fitted with actuators for automated control?
A: Yes. Our valves are designed to be easily coupled with pneumatic (double-acting or spring-return) or electric actuators. We can supply the complete assembly, tested and ready for installation. -
Q: What quality control measures do you have in place?
A: Our ISO9001 certified quality management system governs all processes. We perform material certification checks, dimensional inspections, pressure tests (shell and seat tests per applicable standards), and functional tests before shipment. -
Q: What is your typical lead time for an order?
A: Lead time depends on the valve size, material, and quantity. For standard specifications, it typically ranges from 15 to 45 days. We provide a firm delivery schedule upon order confirmation. -
Q: How do you ensure the valves are packed for sea shipment?
A: Valves are carefully cleaned, dried, and preserved. Internal parts are protected, and flanges are sealed with covers. They are then packed in sturdy wooden cases or pallets suitable for long-distance ocean freight, ensuring they arrive in perfect condition.
