As a leading manufacturer of industrial valves, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our high-performance Bronze Marine Gate Valve designed to CB/T467 standards. With our ISO9001 certified production system and a decade of experience since our establishment in 2016, we deliver valves that meet the rigorous demands of the global maritime industry. Our large-diameter bronze gate valves are engineered for superior durability, exceptional sealing performance, and long-term reliability in critical marine and offshore applications. We provide comprehensive technical support and a readily available inventory of spare parts, ensuring your operations run smoothly and efficiently, minimizing downtime and maintenance costs.
This valve is specifically designed for on/off and isolation services in shipboard piping systems, ballast systems, cooling water lines, and general service applications. Its robust construction ensures dependable performance even under harsh marine conditions. Key features and advantages include:
- Premium Bronze Alloy Body: Manufactured from high-grade bronze (CACB2/C95800), offering excellent corrosion resistance against seawater, salt spray, and a wide range of chemicals commonly found in marine environments.
- Large Diameter Design: Available in sizes from DN50 up to DN600, catering to high-flow applications such as main seawater intakes, fire main lines, and ballast transfer systems.
- Strict Adherence to CB/T467: Compliant with the China Shipbuilding Standard, ensuring dimensional interchangeability, material specifications, and performance criteria suitable for shipbuilding and repair.
- Robust Metal-to-Metal Seal: The wedge and seat provide a tight, bubble-tight shutoff, minimizing leakage and ensuring system integrity.
- Heavy-Duty Construction: Features a strong, non-rising stem design with a large handwheel for easy manual operation, even in larger sizes. The yoke and gland arrangement is designed for easy maintenance and repacking under pressure.
- Versatile Flanged Connections: Standard flanged ends (RF or FF) ensure a secure and leak-free connection to the pipeline, compatible with international flange standards.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of using bronze for marine gate valves?
A: Bronze offers superior corrosion resistance in seawater environments compared to many other metals. It resists dezincification and withstands the corrosive effects of saltwater, making it a preferred and durable material for marine applications. -
Q: Are your CB/T467 valves interchangeable with valves made to other standards like JIS or DIN?
A: While CB/T467 is a Chinese shipbuilding standard, the flange dimensions and pressure ratings are often designed to be compatible with common international standards. It is crucial to provide your specific flange standard and pressure class for verification to ensure proper fit and interchangeability. -
Q: Do you offer these valves in sizes larger than DN600?
A: Our standard production range extends up to DN600. For larger diameters, we can explore custom manufacturing solutions. Please contact our technical sales team with your specific size and pressure requirements for a feasibility assessment and quotation. -
Q: What kind of technical support do you provide?
A: Our support includes assistance with valve selection based on your system parameters, installation guidance, maintenance recommendations, and troubleshooting. We can provide technical datasheets, drawings, and material certifications upon request. -
Q: How readily available are spare parts like glands, stems, or wedges?
A: We maintain an inventory of common spare parts for our valve models. Availability is generally good, and we can provide lead times for specific parts upon inquiry. This helps minimize equipment downtime for our clients. -
Q: Can these valves be operated with actuators for remote control?
A: Yes, the standard handwheel-operated design can be adapted for actuation. The valve features a standard mounting pad suitable for mounting electric, pneumatic, or hydraulic actuators. Actuator selection and supply can be arranged as an optional service. -
Q: What is the typical lead time for an order of large-diameter valves?
A: Lead times depend on the specific size, pressure rating, and order quantity. Standard sizes are often available from stock or have shorter production cycles. We provide estimated lead times with every formal quotation to help you plan your project schedule. -
Q: What documentation accompanies the valves upon delivery?
A: Standard documentation includes a commercial invoice, packing list, and a material test certificate (MTC) for the valve body. Additional certificates, such as a full material traceability report or third-party inspection reports, can be provided upon request and may involve additional charges.
