As a leading manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CB/T467 Cast Bronze Gate Valve with Flanged Ends. Engineered for demanding marine and industrial applications, this valve is specifically designed to handle seawater, oil, and air lines with exceptional performance and longevity. Our focus on precision manufacturing since 2016 ensures that every valve meets the rigorous standards required for global operations. This product represents our dedication to providing robust fluid control solutions that stand up to challenging environments, offering our clients a dependable component for their critical systems.
The core value of this valve lies in its versatile construction and material integrity. The use of high-grade cast bronze provides superior corrosion resistance, particularly against seawater, making it an ideal choice for shipbuilding, offshore platforms, and coastal facilities. Its flanged ends ensure a secure, leak-proof connection that is easy to install and maintain within pipeline networks. We understand that downtime is costly, which is why our valve is built for durability and consistent operation, providing peace of mind for engineers and project managers across various industries.
Detailed Product Features & Technical Specifications:
- Robust Construction: The valve body, bonnet, gate, and seat are meticulously cast from premium bronze alloys, ensuring uniform strength and resistance to galvanic corrosion and erosion from abrasive media like seawater.
- Superior Sealing Performance: Features a precision-machined gate and seat interface that provides a bubble-tight shut-off when fully closed, minimizing pressure drop when fully open, and ensuring reliable isolation of fluid sections.
- Flanged Connection Design: Equipped with standard flanged ends (typically ASME B16.24 or equivalent), facilitating easy bolting to existing pipeline flanges. This design simplifies installation, removal for maintenance, and provides a robust mechanical joint.
- Optimized for Specific Media: The material selection and internal design are tailored for compatibility with seawater (including brackish water), lubricating oils, fuel oils, and compressed air systems, preventing premature degradation.
- Temperature Resilience: Rated for continuous service in environments with media temperatures up to 80°C (176°F), maintaining its mechanical properties and sealing capability within this range.
- Easy Operation & Maintenance: The rising stem design with a handwheel provides clear visual indication of valve position (open/closed). A standardized stuffing box design allows for straightforward packing adjustment or replacement if needed.
- Compliance with Standards: Manufactured in accordance with the Chinese Marine Standard CB/T467, which governs the design, material, and testing requirements for bronze gate valves used in marine applications, ensuring a recognized level of quality.

Advantages and Client Benefits:
- Extended Service Life in Harsh Conditions: The bronze construction offers excellent resistance to seawater corrosion and cavitation, reducing replacement frequency and total cost of ownership for marine and offshore clients.
- Reliable System Integrity: Provides a secure shut-off function, essential for sectioning pipelines for maintenance, preventing cross-contamination of media, or isolating equipment, thereby enhancing overall system safety and control.
- Reduced Maintenance Downtime: The sturdy flanged connection and accessible design simplify inspection and servicing. Common wear parts like packing can be serviced with the valve in line, minimizing operational interruptions.
- Broad Application Compatibility: Its suitability for three key media (seawater, oil, air) allows for inventory standardization across different systems on a vessel or plant, simplifying procurement and spare parts management.
- Global Acceptance: Adherence to the CB/T467 standard, which is recognized in marine sectors, along with common pressure class ratings (125/150), facilitates its specification and approval in international projects.

Frequently Asked Questions (FAQ):
-
Q: What does "CB/T467" in the product title signify?
A: CB/T467 is a Chinese national standard (specifically for the shipbuilding industry) that specifies the technical requirements, testing methods, and acceptance criteria for bronze gate valves. It ensures the valve is designed and manufactured to a recognized set of specifications suitable for marine environments. -
Q: Is this valve suitable for permanent submersion in seawater?
A: While the cast bronze material offers very good corrosion resistance to seawater, its suitability for permanent submersion depends on the specific bronze alloy, water chemistry, and whether it is in a static or flowing condition. It is generally designed for seawater service in pipelines. For specific submerged applications, please consult with our technical team. -
Q: Can the flanged ends be customized to match a specific flange standard (e.g., DIN, JIS, BS)?
A: Yes, customization is often available. While standard production typically aligns with ASME B16.5/B16.24, we can manufacture valves with flange dimensions and drilling to match other common standards like DIN, JIS, or BS upon request. Please provide the required standard and pressure class when inquiring. -
Q: What is the maximum pressure this valve can handle?
A: This valve series is typically rated for Class 125 or Class 150 pressure, which corresponds to approximately 10 bar (150 psi) or 16 bar (235 psi) at the specified maximum temperature of 80°C. The exact pressure rating for a specific size and model should be confirmed from the technical datasheet. -
Q: Does the valve come with any operational accessories like a handwheel lock or position indicator?
A: The standard configuration includes a manual handwheel. Accessories such as locking devices, chain wheels for overhead operation, or position indicators are often available as optional extras. Please specify your accessory requirements during the ordering process. -
Q: What types of gaskets are supplied with the valve, and are they suitable for all listed media?
A: The standard gasket material may vary. Common options include compressed non-asbestos (CNA) or PTFE. For seawater service, gaskets compatible with saltwater corrosion (like certain rubber compounds or PTFE) are recommended. The specific gasket material supplied or recommended can be confirmed based on your application media. -
Q: Is the valve suitable for steam service?
A: No. The maximum temperature rating of 80°C makes it unsuitable for steam lines, which typically operate at much higher temperatures. For steam applications, valves constructed from materials like cast steel or stainless steel with appropriate temperature ratings should be selected. -
Q: What is the lead time for an order of these valves?
A: Lead time depends on the order quantity, valve size, and any customization requirements. For standard sizes and specifications, we generally maintain some stock or can offer competitive production lead times. We provide estimated delivery schedules with every formal quotation.
