As a professional manufacturer with ISO9001-certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing robust and reliable fluid control solutions for demanding marine environments. Our Marine Grade Bronze Gate Valve, designed according to the CB/T467 standard, is engineered to deliver exceptional performance in large-diameter piping systems requiring full, unobstructed flow. This valve represents our commitment to combining traditional craftsmanship with modern manufacturing precision, offering shipbuilders, offshore operators, and marine engineers a durable and trustworthy component for critical applications.
Core Product Features & Technical Advantages:
- Superior Material Integrity: Constructed from high-grade marine bronze alloys (typically conforming to ASTM B61/B62 standards), this valve offers excellent resistance to corrosion from seawater, brackish water, and marine atmospheres, ensuring long service life and minimal maintenance.
- Full Port (Full Bore) Design: The internal flow path is engineered to match the diameter of the connecting pipeline, minimizing pressure drop and turbulence. This design is crucial for systems requiring maximum flow efficiency, such as ballast, bilge, or seawater cooling lines.
- CB/T467 Marine Standard Compliance: Manufactured in strict adherence to the Chinese marine standard CB/T467, ensuring the valve meets specific requirements for dimensions, materials, pressure ratings, and testing protocols suitable for marine and offshore use.
- Robust Sealing & Operation: Features a metal-to-metal seating surface (wedge and seat) for a tight shut-off. The rising stem design provides clear visual indication of valve position. Operation is smooth via a handwheel, with gearbox operators available for larger sizes or high-torque applications.
- Large Diameter Configuration: Specifically designed for main line applications, available in a range of large nominal diameters to suit various ship and platform piping layouts. Common end connections are flanged for secure and leak-proof installation.
- Versatile Application Scope: Ideal for on/off service in seawater systems, fire mains, tank vents, cargo handling systems, and other saltwater or fresh water applications aboard vessels, oil rigs, and port facilities.

Frequently Asked Questions (FAQ):
-
Q: What exactly does "Marine Grade Bronze" mean for this valve?
A: "Marine Grade Bronze" refers to specific bronze alloys, often containing tin, nickel, or aluminum, formulated for superior corrosion resistance in seawater environments compared to standard bronzes. The exact composition can be specified to meet standards like ASTM B61 or B62. -
Q: How does the CB/T467 design differ from other gate valve standards like API or JIS?
A: CB/T467 is a Chinese national standard specifically for marine valves. It defines requirements for dimensions, materials, pressure-temperature ratings, and testing methods tailored for marine applications, ensuring suitability for shipboard and offshore use. -
Q: Why is a Full Port (Full Bore) design important for my application?
A: A Full Port design has an internal bore diameter equal to the nominal pipe size. This eliminates flow constriction, reduces pressure loss, and prevents clogging in systems carrying seawater or other fluids with potential solids, which is vital for efficiency and maintenance. -
Q: Can this valve be used for throttling or flow control?
A: Gate valves are primarily designed for isolation (fully open or fully closed). Using them for throttling can cause vibration, wire-drawing (erosion) of the seat, and premature wear. They are recommended for on/off service only. -
Q: What are the available pressure ratings and how do I choose?
A: Common ratings include PN10, PN16 (metric), or 150LB (imperial). The choice depends on your system's maximum working pressure. We can advise based on your application details to ensure a safe and suitable selection. -
Q: Do you offer modifications like gear operators or different flange standards?
A: Yes. Gear operators are available for large-diameter valves to reduce operating torque. Flanges can be manufactured to various standards (e.g., JIS, DIN, ANSI) upon request. Customization options are part of our service. -
Q: What is the typical lead time for a large-diameter, custom-configured order?
A: Lead time varies based on order quantity and specific requirements. As a manufacturer, we can provide efficient production scheduling. Please inquire with your detailed specifications for an accurate timeline. -
Q: What kind of testing do these valves undergo before shipment?
A: Valves undergo standard factory tests which typically include shell strength tests (hydrostatic) and seat leakage tests as per the relevant standards (CB/T467) to ensure integrity and performance.
