Our commitment is reflected in the comprehensive full warranty covering both the body and internal components, ensuring long-term value and peace of mind for our clients.
The CBT4303 valve is specifically designed for applications requiring automatic prevention of backflow in pipelines. Its core functionality lies in the butterfly-style disc, which opens under forward flow pressure and swiftly closes when flow diminishes or reverses, protecting upstream equipment and maintaining system integrity.
Key Features & Technical Advantages:
- Bronze Construction: The body and critical components are crafted from bronze, offering excellent resistance to corrosion, particularly in water-based systems. This material choice enhances longevity and reduces maintenance needs.
- Butterfly Disc Design: Utilizes a lightweight, balanced butterfly disc. This design ensures quick response times for closing, minimizing pressure drop during forward flow, and providing reliable sealing against backflow.
- Full Warranty Coverage: We provide a full warranty on the valve body and all internal components, underscoring our confidence in the product's quality and durability. This warranty supports our promise of reliable performance.
- Versatile Applications: Ideal for use in potable water systems, HVAC (Heating, Ventilation, and Air Conditioning) circuits, industrial process lines, and general service pipelines where backflow prevention is critical.
- Quality Assurance: Manufactured under an ISO9001 certified quality management system, ensuring consistent production standards, material integrity, and performance reliability.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of using a bronze material for this check valve?
A: Bronze offers superior corrosion resistance compared to many other metals, especially in water applications. This extends the valve's service life and reduces maintenance issues related to rust or degradation. -
Q: How does the butterfly disc mechanism work in this check valve?
A: The butterfly disc is hinged within the valve body. Under forward flow pressure, the disc swings open, allowing fluid passage. When flow stops or reverses, the disc automatically swings back to its closed position, sealing the pathway against backflow. -
Q: What does the "full warranty on body and components" cover?
A: The warranty covers defects in materials and workmanship for the main valve body and its internal components (such as the disc, hinge, and seal) under normal operating conditions. Specific terms are provided upon purchase. -
Q: Can the CBT4303 valve be customized for specific pipe sizes or connection types?
A: Yes. We offer customization options for size (to match your pipeline diameter) and connection type (e.g., flanged or threaded). Please contact us with your requirements for a tailored solution. -
Q: Is this valve suitable for use in potable (drinking) water systems?
A: The bronze construction is commonly used in water applications. However, suitability for potable water depends on specific local standards and regulations. We recommend consulting relevant codes or inquiring about optional material certifications for such applications. -
Q: What are the typical industries or applications for this valve?
A: Common applications include municipal and commercial water supply systems, HVAC heating/cooling circuits, industrial process pipelines carrying water or compatible fluids, and general service lines where backflow prevention is required. -
Q: How does the ISO9001 certification relate to this product?
A: Our ISO9001 certification means our entire manufacturing and quality management processes follow international standards for consistency, documentation, and continuous improvement. This ensures every CBT4303 valve is produced under controlled, reliable conditions. -
Q: What ports does Shanghai Zhibang Valve use for export shipment?
A: We primarily ship from Shanghai, Guangzhou, Hong Kong, and Beijing ports, facilitating efficient logistics to our main markets worldwide.
