As a professional valve manufacturer, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CB/T467-1995 Standard Bronze Marine Flanged Gate Valve, engineered to meet the rigorous demands of marine applications. With our commitment to quality since 2016 and backed by ISO9001 certification, we deliver reliable flow control solutions trusted by clients across the globe from North America to Southeast Asia. This valve is designed for durability and precise operation in critical shipboard piping systems, offering a robust sealing solution for seawater, ballast, and general service lines.
Our Bronze Marine Flanged Gate Valve is manufactured in strict compliance with the Chinese marine standard CB/T467-1995, ensuring compatibility and reliability for shipbuilding and repair projects. The flanged connection design facilitates secure and leak-free installation, which is paramount in the marine environment. The product range covers sizes from DN15 to DN200 and pressure classes from PN1.0 to PN4.0 MPa, providing versatile options for various system requirements.
Key Features & Technical Advantages:
- Superior Material Construction: The valve body, bonnet, disc, and stem are crafted from high-grade bronze, offering excellent corrosion resistance against seawater and marine atmospheres, ensuring long service life.
- Robust Flanged Design: The flanged ends conform to standard dimensions, ensuring easy integration into existing marine piping networks and providing a sturdy, bolted connection that withstands vibration and pressure fluctuations.
- Precise Flow Control: The gate valve design ensures a straight-through flow path with minimal pressure drop when fully open, and provides a tight, bubble-tight shut-off when closed, which is critical for system isolation.
- Standard Compliance: Adherence to the CB/T467-1995 standard guarantees that the valve meets specific requirements for materials, dimensions, pressure-temperature ratings, and testing methods for marine use.
- Versatile Pressure & Size Range: Available in a comprehensive spectrum from DN15 to DN200 and PN1.0 to 4.0 MPa, allowing for selection across different system pressures and pipe diameters onboard vessels.
- Reliable Sealing: The wedge disc and bronze seat provide a metal-to-metal seal suitable for the operating conditions typical in marine engineering, with optional soft-seated designs available for specific applications.

Frequently Asked Questions (FAQ):
-
What does the "CB/T467-1995" standard signify for this valve?
This is a Chinese national professional standard specifically for marine valves. It defines the technical requirements, materials, dimensions, pressure ratings, and test methods for bronze gate valves used in shipbuilding, ensuring they are fit for marine service. -
Is this bronze valve suitable for seawater applications?
Yes, absolutely. The bronze alloy used offers inherent corrosion resistance against seawater, making it a preferred material for marine ballast, cooling, and general service lines. -
Can I get valves with different flange standards, like ANSI or JIS?
While the standard product is manufactured to the dimensions referenced in CB/T467-1995, we can often accommodate requests for other flange standards (e.g., ANSI, JIS) as a customization option. Please inquire with our sales team for specific requirements. -
What is the maximum working pressure for the PN4.0 MPa model?
The PN4.0 MPa rating indicates a nominal pressure of 40 bar. The maximum allowable working pressure will depend on the fluid temperature. Detailed pressure-temperature charts are available upon request. -
Do you provide test reports or certifications with the valves?
As a standard practice, our valves undergo factory testing. Detailed test reports, such as shell test and seat leak test reports, can be provided. Our manufacturing facility is ISO9001 certified. -
What is the lead time for an order of DN100 valves?
Lead times vary based on order quantity and current production schedule. Generally, for standard sizes and pressures, we maintain stock or can produce within a reasonable timeframe. Contact us with your required quantity for an accurate delivery estimate. -
Are spare parts like gland packing or gaskets available?
Yes, we can supply genuine spare parts kits for maintenance purposes. It is recommended to order spares along with the valves to ensure compatibility and availability. -
Can this valve be operated with an actuator for remote control?
The standard valve is designed for manual operation via a handwheel. However, modifications for the attachment of electric, pneumatic, or hydraulic actuators are possible. Please discuss your automation needs with our engineering team.
