As a professional valve manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing reliable fluid control solutions for the marine industry. Our CB/T590 Globe Valve is engineered specifically for the demanding environment of ship fuel oil lines, where safety and durability are non-negotiable. With years of experience and a commitment to quality, we have designed this valve to offer superior shut-off performance, ensuring the secure and efficient management of fuel flow on vessels. This product represents our dedication to meeting the stringent standards of maritime applications, providing shipbuilders and operators with a component they can trust for critical systems.
The CB/T590 Globe Valve is a cornerstone of marine fuel system safety. Its design prioritizes a tight seal and reliable operation under the variable pressures and corrosive conditions found at sea.
- Robust Construction for Harsh Environments: The valve body is typically manufactured from high-grade cast steel or ductile iron, providing excellent resistance to mechanical stress and corrosion from marine atmospheres and fuel oils. Internal components like the stem and disc are often made from stainless steel or hardened alloys to prevent galling and ensure smooth, long-lasting operation.
- Superior Sealing Performance: The globe valve design, with its linear motion and perpendicular seating, allows for precise flow regulation and a bubble-tight shut-off. This is critical for fuel oil lines to prevent leaks and ensure system isolation during maintenance or emergencies.
- Flanged Connection for Secure Installation: The flanged ends are machined to precise standards, ensuring a perfect match with pipeline flanges. This connection method provides a strong, leak-proof joint that can withstand vibration and pipeline movement common in shipboard installations.
- Ease of Operation and Maintenance: Available with a standard handwheel or optional gear operator for larger sizes (DN150-DN200), the valve is designed for easy manual control. The bolted bonnet design allows for straightforward internal inspection, seat replacement, or packing adjustment without removing the valve from the line, minimizing downtime.
- Compliance with Marine Standards: Manufactured in accordance with the Chinese CB/T590 standard for marine valves, this product is designed to meet the specific requirements of shipboard use, including materials, pressure ratings, and testing protocols.

Frequently Asked Questions (FAQ)
Q1: Is this valve suitable for heavy fuel oil (HFO) service?
A: Yes, it is designed for ship fuel oil lines, which typically include marine diesel oil (MDO) and heavy fuel oil. Material selections like hardened alloy seats (e.g., Stellite) are recommended for HFO service to resist abrasion from catalytic fines.
Q2: Can you provide valves with flanges to ASME B16.5 standard instead of GB standard?
A: Yes, we can customize the flange dimensions and drilling to meet various international standards, including ASME B16.5, JIS, or DIN, upon request. Please specify your requirement when inquiring.
Q3: What is the lead time for an order of DN100 valves?
A: Lead time depends on the order quantity and specific material configuration. For standard WCB body with 13Cr trim, we typically have a shorter lead time. We recommend contacting us with your desired quantity for an accurate production schedule.
Q4: Do you offer full documentation with the valves, such as test reports and material certificates?
A: Yes, we provide standard documentation including a product certificate, hydrostatic test report, and material chemical composition reports. More detailed certification packages are available upon request.
Q5: Is the valve suitable for both above-deck and engine room installations?
A: The valve is designed for general shipboard use in fuel oil lines. For specific exposed locations (above deck), considerations like additional corrosion protection (e.g., epoxy coating) may be discussed based on the exact service environment.
Q6: Can the valve be operated remotely or only manually?
A> The standard configuration is manual operation via handwheel or gear. However, we can discuss the possibility of providing a design suitable for the attachment of an electric or pneumatic actuator for remote operation as a customized solution.
Q7: What kind of pressure testing is performed on each valve?
A: Each valve undergoes a shell test and a seat leak test (typically using water or air) as per the CB/T590 standard and our internal quality procedures to ensure integrity before shipment.
Q8: Are spare parts like gasket sets and packing readily available?
A: Yes, we recommend and can supply maintenance kits containing essential spare parts to ensure you have them on hand for planned maintenance, helping to avoid prolonged downtime.
