As a dedicated manufacturer with a strong focus on maritime and industrial fluid control, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents its high-performance CB/T467 Bronze Gate Valve. Engineered specifically for demanding bilge and ballast systems onboard vessels, this valve represents a reliable solution where durability and leak-tight shut-off are non-negotiable. Our commitment to the ISO9001 quality management system ensures that every valve undergoes rigorous production and inspection processes, guaranteeing consistent performance that shipbuilders and marine engineers can trust. With years of experience serving global markets from North America to Southeast Asia, we understand the critical role these components play in vessel safety and operational efficiency.
This valve is designed to meet the exacting standards of marine applications, offering robust construction and dependable operation in challenging environments.
- Superior Material Integrity: Manufactured from premium bronze alloys (typically CAC406 or equivalent UNS C84400), the valve offers excellent resistance to seawater corrosion, dezincification, and erosion. This material choice ensures a long service life even with constant exposure to saline and brackish water in bilge and ballast systems.
- CB/T467 Compliance: The valve is designed and produced in strict accordance with the Chinese CB/T467 standard for shipbuilding, which specifies requirements for bronze flanged gate valves. This compliance assures compatibility with marine piping specifications and provides a recognized benchmark for quality and dimensions.
- Reliable Sealing Mechanism: Features a solid wedge or flexible wedge disc design. The solid wedge provides a robust seal for general applications, while the flexible wedge can compensate for minor seat alignment changes due to pipeline stress or temperature fluctuations, enhancing sealing reliability.
- Rising Stem Design: The outside screw and yoke (OS&Y) with a rising stem provides a clear visual indication of the valve's open or closed position, a critical safety feature for marine operations. The stem threads are isolated from the line media, preventing corrosion and ensuring smooth operation.
- Robust Flanged Connections: Equipped with standard flanged ends as per relevant flange standards (e.g., JIS, ANSI, GB), facilitating secure and leak-proof installation into the piping system. This design simplifies maintenance and replacement procedures.
- Durable Construction: Key components like the handwheel, gland, and packing are designed for durability. The gland follower allows for easy adjustment of the stem packing to maintain a proper seal around the stem, preventing external leakage.

Frequently Asked Questions (FAQ):
-
Q: Is this valve suitable for seawater applications?
A: Yes, absolutely. The bronze alloy used (like CAC406) is specifically chosen for its excellent resistance to corrosion by seawater, making it a standard material for marine valves in bilge, ballast, and seawater cooling lines. -
Q: What is the meaning of "CB/T467" in the product title?
A: CB/T467 is a Chinese industry standard ("CB" stands for Shipbuilding Standard) that details the technical requirements, dimensions, materials, and testing methods for bronze flanged gate valves used in shipbuilding. Compliance ensures the valve meets recognized specifications for marine use. -
Q: Can this valve be supplied with different flange standards, like ANSI or JIS?
A: Yes, customization is often possible. While it is produced to CB/T467, we can frequently accommodate requests for flanges matching ANSI, JIS, or other standards based on your piping system design. Please specify your requirement when inquiring. -
Q: What is the difference between a solid wedge and a flexible wedge?
A: A solid wedge is a single-piece disc, very robust and suitable for most applications. A flexible wedge has a cut around its perimeter, allowing slight flexing. This can provide better sealing in situations where thermal expansion or pipe strain might cause minor seat distortion. -
Q: Do you provide certificates with the valves?
A: As an ISO9001 certified manufacturer, we can provide standard material certificates and factory test reports (e.g., shell test, seat test) upon request. Specific certification requirements should be discussed at the time of order. -
Q: What is the typical lead time for an order?
A: Lead time depends on the order quantity, size, and specific configuration. For standard sizes and moderate quantities, production can often be completed within a few weeks. We provide accurate lead time estimates with every quotation. -
Q: Are the valves tested before shipment?
A: Yes, each valve undergoes routine production tests, which typically include a hydrostatic shell test and a seat leakage test to ensure integrity and sealing performance before leaving our factory. -
Q: What after-sales support do you offer?
A: We offer technical support for installation and operation. While valves are designed for durability, we can assist with troubleshooting and guide you to local service agents or provide spare parts if needed.
