As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve is dedicated to providing high-quality marine valves. Our CB/T467-1995 Bronze Gate Valve is engineered specifically for the demanding environment of marine ballast systems. It offers reliable flow control, excellent corrosion resistance, and long-term durability, ensuring the safety and efficiency of your vessel's operations. Trust our expertise to deliver valves that meet stringent maritime standards.
This valve is designed for precise on/off control of seawater in ballast tanks. Its robust construction and adherence to the marine-specific CB/T467-1995 standard make it a critical component for maintaining vessel stability and trim.
- Superior Corrosion Resistance: Manufactured from high-grade bronze, the valve exhibits outstanding resistance to saltwater corrosion, preventing premature failure and reducing maintenance needs in harsh marine environments.
- Reliable Sealing Performance: Features a precision-machined wedge disc and seat that ensure a bubble-tight seal, effectively preventing leaks in the ballast system, which is crucial for vessel safety and environmental compliance.
- Robust and Durable Construction: The valve body is designed to withstand high pressures and the mechanical stresses common in shipboard piping systems, offering a long service life even under continuous operation.
- Smooth Operation: Equipped with a handwheel (or optional gear operator) and a rising stem design, allowing for easy and clear visual indication of the valve position, facilitating quick and safe operation by crew members.
- Standard Compliance: Strictly manufactured in accordance with the Chinese Marine Standard CB/T467-1995, ensuring compatibility and reliability within marine engineering specifications.
- Versatile Configurations: Available in various sizes, pressure ratings, and connection types to suit different piping layouts and system requirements on various types of vessels.

Frequently Asked Questions (FAQ)
-
Q: What is the significance of the CB/T467-1995 standard for this valve?
A: CB/T467-1995 is a Chinese national marine industry standard. Valves conforming to this standard are designed and tested specifically for marine applications, ensuring materials, dimensions, pressure ratings, and performance are suitable for shipboard use, particularly in critical systems like ballast control. -
Q: Can this bronze valve handle seawater effectively?
A: Yes, absolutely. The selected bronze alloy offers excellent resistance to corrosion from seawater, making it a preferred material for marine valves handling seawater, such as those in ballast and cooling systems. -
Q: Are other operation methods available besides a handwheel?
A: Certainly. While standard models come with a handwheel, we can provide valves equipped with gear operators for high-torque applications or even automated actuators (electric or pneumatic) for remote control integration, available upon request. -
Q: What is the typical delivery lead time for an order?
A: Lead time depends on the order quantity and specific configuration. For standard sizes and specifications, we generally maintain stock for faster delivery. Customized orders may require additional production time. Please inquire with your specific needs for an accurate timeline. -
Q: Do you provide documentation like material certificates and test reports?
A: Yes, we provide essential documentation including material test certificates and factory hydrostatic test reports as standard. Additional certifications can be discussed based on your project requirements. -
Q: Is this valve suitable for other marine applications beyond ballast systems?
A: While optimized for ballast control, this bronze gate valve is also suitable for other marine services involving seawater, fresh water, air, or non-aggressive oils, such as cooling water lines, general service lines, and tank filling/discharge lines. -
Q: What after-sales support do you offer?
A: We offer technical support for installation and operation. Furthermore, we maintain a supply of common spare parts like gland packings and gaskets to support maintenance needs during the valve's service life. -
Q: How do I determine the correct valve size and pressure rating for my system?
A> Please provide your pipeline's nominal diameter (DN or NPS) and the system's maximum working pressure. Our technical team can then recommend the appropriate PN rating (e.g., PN16) and connection type to ensure a proper fit and safe operation.
