As a leading manufacturer in the valve industry, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our premium CB/T467-1995 Bronze Gate Valve. Established in 2016, we have dedicated ourselves to engineering high-performance fluid control solutions for demanding applications worldwide. This specific valve is engineered to meet the rigorous CB/T467-1995 standard, making it a reliable and essential component for marine engineering and shipbuilding projects. We understand the critical need for durability and safety in maritime environments, and our valve is designed to deliver exceptional sealing performance and long-term service life, ensuring the smooth operation of your vessel's piping systems.
This valve is meticulously crafted to provide superior flow control and isolation in seawater, freshwater, fuel oil, and lubricating oil lines on ships and offshore platforms. Its robust construction and adherence to specialized marine standards make it a trusted choice for engineers and procurement managers.
- Standard Compliance & Reliability: Strictly manufactured according to the Chinese Shipbuilding Standard CB/T467-1995. This ensures the valve's design, materials, dimensions, and testing procedures are specifically tailored for the harsh conditions of marine service, offering peace of mind and regulatory compliance.
- Premium Bronze Material: The valve body, bonnet, gate, and seat are primarily made of high-grade bronze casting. This material offers excellent resistance to seawater corrosion, dezincification, and cavitation, which is crucial for longevity in saltwater environments.
- Robust Sealing Performance: Features a precision-machined gate and seat interface. Options include metal-to-metal sealing for high-temperature applications or a resilient seat (e.g., PTFE) for bubble-tight shut-off in lower-temperature services.
- Versatile Design & Operation: Available in a wide range of sizes and pressure classes to suit various pipeline requirements. It can be operated via a standard handwheel, gearbox for high-torque applications, or automated with pneumatic/electric actuators for remote control.
- Durable Stem Packing: Equipped with high-quality packing material like reinforced graphite or PTFE, ensuring a reliable stem seal that minimizes leakage and requires less maintenance.
- Easy Maintenance & Installation: Designed with a bolted bonnet for easy access to internal parts, facilitating inspection, repair, or replacement without removing the entire valve from the pipeline. Standard flanged or threaded ends simplify installation.

Frequently Asked Questions (FAQ):
-
Q: What is the significance of the CB/T467-1995 standard for this valve?
A: The CB/T467-1995 is a Chinese national standard specifically for marine bronze gate valves. It defines the technical requirements, materials, dimensions, and test methods to ensure the valve's suitability and reliability for shipboard use, particularly in corrosive seawater environments. -
Q: Can this valve be used for fluids other than seawater?
A: Yes. While optimized for marine service, its bronze construction offers good resistance to various media, including freshwater, fuel oil, lubricating oil, air, and steam. Always confirm media compatibility for your specific application. -
Q: What are the available pressure classes and how do I choose?
A: Standard pressure ratings are PN10, PN16, and PN25. The selection depends on your system's maximum working pressure. PN16 is a common choice for many marine piping systems. Our technical team can assist you based on your system specifications. -
Q: Is the valve suitable for automated control systems?
A> Absolutely. The valve can be fitted with pneumatic or electric actuators for remote or automated operation. This is an optional feature available upon request. Please specify your automation requirements when inquiring. -
Q: What is the lead time for an order?
A: Lead time varies based on order quantity, size, and configuration. Standard sizes are typically available from stock or have shorter production cycles. We provide estimated lead times with every quotation to help you plan your project schedule. -
Q: Do you provide documentation like material certificates and test reports?
A: Yes. We can provide necessary documentation, including material chemical composition and mechanical property certificates, as well as factory test reports (e.g., shell test, seat test) in accordance with the standard. This is part of our quality assurance process. -
Q: How does the corrosion resistance of bronze compare to other materials like stainless steel for marine use?
A: Bronze, particularly aluminum bronze or nickel-aluminum bronze, offers excellent resistance to seawater corrosion and biofouling. It is often preferred for seawater applications due to its proven history, castability for complex shapes, and good bearing properties, which are beneficial for the gate and seat interaction. -
Q: Can you produce valves with non-standard dimensions or specifications?
A: We have engineering capabilities for customizations. Modifications to dimensions, pressure ratings, or special coatings can be discussed. Contact us with your detailed requirements for a feasibility assessment and custom quote.
