As a specialized manufacturer with a strong focus on marine fluid control solutions, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CB/T467 Bronze Gate Valve with Flanged Ends. Engineered for demanding marine environments, this valve series combines the inherent corrosion resistance of bronze with robust construction to deliver reliable, long-lasting shut-off performance in critical shipboard piping systems. Our commitment to quality, backed by ISO9001 certification, ensures every valve meets stringent standards for safety and durability, providing shipbuilders, shipowners, and marine engineers with a trustworthy component for their global operations.
This valve is designed to excel in the harsh conditions of marine applications, where saltwater corrosion, vibration, and pressure fluctuations are constant challenges. The selection of high-grade bronze as the primary body material is a strategic choice, offering superior resistance to seawater corrosion compared to many other metals. The flanged end design facilitates secure, leak-proof connections to piping systems, simplifying installation and maintenance procedures onboard vessels. Whether it's for ballast systems, cooling water lines, fuel oil transfer, or general service applications, this gate valve provides a robust and dependable solution.
Key Features and Technical Advantages:
- Superior Corrosion Resistance: The bronze body and key internal components effectively withstand the corrosive effects of seawater and marine atmospheres, ensuring a longer service life and reducing maintenance frequency.
- Robust Flanged Connection: The flanged ends are precision-machined to ensure a perfect fit and seal with standard pipe flanges, preventing leaks and enhancing system integrity under high pressure and vibration.
- Wide Size and Pressure Range: Available from DN50 to DN300 and rated for pressures from PN1.6 to PN4.0 MPa, this series offers versatile solutions for various pipe diameters and system pressure requirements onboard.
- Reliable Shut-Off Function: The gate valve design provides a straight-through flow path when open, minimizing pressure drop, and a tight, bubble-tight seal when closed, ensuring positive isolation of pipeline sections.
- Durable Construction: Manufactured in compliance with the CB/T467 standard, which specifies requirements for marine valves, ensuring dimensional accuracy, material quality, and performance suitable for maritime use.
- Smooth Operation: The stem is designed for easy manual operation, even after prolonged periods of inactivity, thanks to careful design and material selection to prevent seizing.

Frequently Asked Questions (FAQ):
-
Q: What does the "CB/T467" standard signify for this valve?
A: CB/T467 is a Chinese national standard specifically for marine valves. It defines the technical requirements, testing methods, and acceptance criteria for valves used on ships, ensuring they are suitable for the marine environment in terms of materials, pressure ratings, and dimensions. -
Q: Why is bronze the preferred material for marine gate valves?
A: Bronze offers an excellent balance of strength, machinability, and, most importantly, high resistance to corrosion from seawater and salt-laden air. This makes it a traditional and reliable choice for many marine fluid applications. -
Q: Can this valve be used with fluids other than seawater?
A: Yes. While optimized for marine service, this bronze gate valve is also suitable for a range of other non-corrosive or mildly corrosive fluids such as freshwater, compressed air, oil, and steam within its pressure and temperature limits. -
Q: What flange standards are compatible with these valves?
A: The valves are manufactured to match common international flange standards such as ISO, DIN, ANSI/ASME, or JIS. The specific standard (e.g., PN10/16, Class 150) should be specified at the time of ordering to ensure compatibility with your existing piping. -
Q: Is the valve suitable for frequent operation?
A: As a gate valve, it is primarily designed for infrequent operation as a shut-off valve, not for throttling or frequent cycling. For applications requiring regular adjustment, other valve types like globe valves may be more appropriate. -
Q: Do you offer different stem packing materials?
A: Standard packing is suitable for general service. For specific media or temperature requirements, alternative packing materials such as graphite or PTFE can be available upon request. -
Q: What is the lead time for an order of DN200, PN2.5 valves?
A: 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 competitive timeframe. Please inquire with your specific quantity for an accurate delivery estimate. -
Q: Are testing certificates provided with the valves?
A: Yes, as part of our ISO9001 quality system, valves undergo pressure tests (shell and seat tests) as per standard requirements. Relevant test certificates can be provided with the shipment.
