As a leading manufacturer with a strong commitment to quality, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CB/T467 series Large Diameter Bronze Gate Valves. Engineered for demanding industrial applications, these valves are designed to provide reliable shut-off and control in large-scale piping systems handling water, oil, gas, and steam. Our decade of experience since 2016, backed by ISO9001 certification, ensures that every valve delivers the durability and performance our global clients from North America to Southeast Asia have come to expect. This product line represents our dedication to combining robust materials with precise engineering to meet the challenges of high-flow environments.
Our CB/T467 Bronze Gate Valves are constructed to offer superior service life and dependable operation. The key features and advantages include:
- Premium Bronze Construction: The valve body and critical internal components are crafted from high-grade bronze, offering excellent corrosion resistance, good machinability, and reliable performance across a wide temperature range. This makes them suitable for various media, including seawater and certain chemicals.
- Robust Flanged Design: Featuring a flanged connection per relevant standards, these valves ensure a secure, leak-proof, and easy-to-install interface with the pipeline, simplifying maintenance and reducing installation time.
- Wide Size and Pressure Range: Available in a comprehensive range from DN150 to DN500 and pressure classes from PN1.0 to PN2.5 MPa, providing flexibility for system designers and engineers to select the perfect fit for their specific flow and pressure requirements.
- Metal-Seated Reliability: Utilizes a metal-to-metal seat design, which offers enhanced durability and tight sealing under high-pressure conditions compared to soft-seated alternatives, minimizing the risk of internal leakage over time.
- Ergonomic Operation: The handwheel operation is designed for smooth and manageable actuation even at larger diameters, reducing operator effort. Options for rising or non-rising stems are available to suit different spatial and indication needs.

Frequently Asked Questions (FAQ)
-
Q: What are the main applications for this large diameter bronze gate valve?
A: These valves are commonly used for isolation and on/off control in large piping systems for seawater cooling, potable water distribution, oil and gas pipelines (non-critical), low-pressure steam lines, and industrial water treatment plants. -
Q: Why choose bronze for a gate valve of this size?
A: Bronze offers an excellent balance of strength, corrosion resistance (especially against seawater), and machinability. For large diameters, it provides durability without the excessive weight and cost of some alternative materials, making it a practical choice for many applications. -
Q: Are the flanges drilled according to a specific standard?
A: Standard valves are supplied with flanges drilled to common international standards like ISO or ANSI. The specific drilling standard can be confirmed or customized upon request to match your existing pipeline flanges. -
Q: What is the difference between PN1.0, PN1.6, and PN2.5 MPa pressure ratings?
A: These denote the maximum allowable working pressure at a reference temperature (usually ambient). PN1.0 equals 10 bar, PN1.6 equals 16 bar, and PN2.5 equals 25 bar. Selecting the correct rating is crucial for safe system operation based on your design pressure. -
Q: Can these valves be operated with actuators?
A: While designed for manual handwheel operation, the valve design can typically be adapted for mounting electric, pneumatic, or hydraulic actuators for remote or automated control. Please inquire about actuator mounting kits. -
Q: Do you offer a full port (full bore) design in these sizes?
A: The standard design is a regular port gate valve. A full port version, which minimizes pressure drop, may be available as a special order. Please contact our technical team with your specific requirements. -
Q: What kind of warranty or after-sales support do you provide?
A: Our products are backed by a standard warranty against manufacturing defects. We also provide comprehensive technical documentation and support. Spare parts like gland packing and gaskets are available for purchase. -
Q: How do I determine the correct size (DN) for my application?
A: The valve size should match the nominal diameter of your connecting pipeline. Key factors are the required flow rate and allowable pressure drop. Our engineering team can assist you in selection if you provide system parameters such as flow, pressure, and media.
