As a leading manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance marine valves. Our CB/T3191 Marine Fuel Oil Ball Valve is engineered for critical service in ship fuel systems and bunkering operations. We combine rigorous manufacturing standards with comprehensive testing to deliver a valve that ensures reliable flow control, safety, and longevity in demanding maritime environments. With an annual export value reflecting our global reach, we are committed to providing robust solutions trusted by clients across North America, Southeast Asia, Europe, and beyond.
This valve is designed to meet the specific challenges of handling marine fuel oils. Its construction prioritizes durability and leak-tight sealing to prevent costly spills and operational downtime.
- Superior Sealing Performance: Features advanced seat materials like PTFE or metal, ensuring a bubble-tight seal even after prolonged exposure to fuel oils and varying pressures.
- Robust Construction: Manufactured from high-grade carbon steel or corrosion-resistant stainless steel, providing excellent mechanical strength and resistance to marine atmospheric conditions.
- Easy Operation & Maintenance: The quarter-turn operation allows for quick opening and closing. A streamlined body design minimizes pressure drop and facilitates easier inline maintenance.
- Versatile Configurations: Available in a full range of sizes and pressure classes to fit diverse piping specifications and system requirements onboard vessels.
- Enhanced Safety: The full-port or reduced-port design ensures safe and efficient flow, while the blow-out-proof stem adds an extra layer of operational security.

Frequently Asked Questions (FAQ)
-
Q: What is the significance of the CB/T3191 standard for this valve?
A: CB/T3191 is a Chinese national standard specifically for marine valves. It defines the design, material, manufacturing, testing, and inspection requirements to ensure the valve's suitability and safety for marine applications, particularly in fuel systems. -
Q: Is the Mill Test Report (MTR) provided for every valve?
A: Yes, a comprehensive Mill Test Report is provided as standard. This document certifies the chemical composition and mechanical properties of the raw materials used, offering full traceability and quality verification. -
Q: What does the pressure testing involve?
A: Each valve undergoes hydrostatic shell and seat pressure tests according to relevant standards (e.g., API 598). The test pressure typically exceeds the valve's rated working pressure to confirm its structural integrity and leak-tightness before shipment. -
Q: Can this valve handle different types of marine fuel oil?
A: Absolutely. The valve is designed for various marine fuels, including IFO, MDO, and MGO. Material compatibility, especially for seals, can be selected based on the specific fuel's properties and operating temperature. -
Q: Are actuators available for remote operation?
A: Yes. While supplied as standard with a manual lever, the valve can be fitted with pneumatic, electric, or hydraulic actuators. Please specify your requirements for actuation when inquiring. -
Q: How does the 12-month warranty work?
A: Our warranty covers defects in materials and workmanship under normal use for 12 months from the date of shipment. It assures you of our commitment to product quality and provides peace of mind for your purchase. -
Q: What are the main delivery ports and lead times?
A: We ship regularly from Shanghai, Guangzhou, and Hong Kong ports. Standard product lead times are typically 4-6 weeks, but expedited options may be available for urgent requirements. -
Q: Do you offer custom markings or packaging?
A: Customized markings like client's logo or part numbers on the valve body are available. Export-standard wooden cases or pallets are used for packaging to ensure safe ocean freight transportation.
