Zhibang Valve
As a leading manufacturer with over 8 years of expertise in industrial valve production, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our premium Marine Bronze Gate Valve engineered to the rigorous CB/T467 standard. Designed specifically for the demanding environment of seawater systems, this handwheel-operated valve offers superior corrosion resistance, reliable shut-off, and long service life, ensuring the safety and efficiency of your maritime and offshore operations. Our commitment to ISO9001-certified quality management guarantees that every valve meets the highest standards of performance and durability, making it a trusted component for shipbuilders, shipyards, and marine engineers worldwide.
This valve is meticulously crafted to handle the unique challenges posed by seawater, which is highly corrosive due to its salt content. We understand that system failure is not an option in marine applications, which is why our product is built for resilience and dependable performance.
Key Features and Technical Advantages:
- Superior Corrosion Resistance: The valve body, bonnet, and trim are manufactured from high-grade marine bronze (CuZnAl alloy), specifically formulated to withstand the corrosive effects of seawater, brackish water, and other marine fluids far better than standard bronze or brass alloys.
- Rigorous CB/T467 Compliance: Manufactured in strict accordance with the Chinese CB/T467 standard for marine valves, ensuring design, material, testing, and performance criteria are met for marine service. This provides assurance of quality and suitability for critical shipboard systems.
- Robust and Reliable Sealing: Features a metal-to-metal wedge and seat design. This construction provides a bubble-tight shut-off when fully closed and is highly resistant to wear, erosion, and galling, even after frequent cycling.
- Ergonomic Handwheel Operation: The large, sturdy handwheel allows for smooth and easy manual operation, even under higher differential pressures. The design reduces operator effort and provides clear visual indication of the valve position (open/closed).
- Versatile Pressure and Size Range: Available in a comprehensive range of sizes and pressure classes to suit various pipeline requirements within seawater systems, from auxiliary lines to main cooling circuits.
- Durable Stem Design: The rising stem design with external threads ensures that the stem threads are not in contact with the line fluid, preventing corrosion and binding, which contributes to easier operation and maintenance.

Frequently Asked Questions (FAQ)
-
Q: What makes "marine bronze" different from standard bronze used in valves?
A: Marine bronze, often a copper-zinc-aluminum (CuZnAl) alloy, contains specific additives that significantly enhance its resistance to dezincification and corrosion in saltwater environments. Standard bronze valves may corrode rapidly when exposed to seawater. -
Q: Is this valve suitable for use in freshwater systems as well?
A: Absolutely. While optimized for seawater, its superior corrosion resistance makes it an excellent and durable choice for freshwater, brackish water, and other non-aggressive fluids. -
Q: Can this valve be supplied with actuators for remote operation?
A: While this specific model is handwheel-operated, we offer a range of gate valves that can be fitted with electric, pneumatic, or hydraulic actuators. Please inquire for automated solutions. -
Q: What flange standards do you offer?
A: We typically manufacture flanges to common international standards such as ANSI/ASME B16.5, JIS, DIN, and GB standards. The specific standard can be confirmed based on your order requirements. -
Q: How do you ensure the valve meets the CB/T467 standard?
A: Our manufacturing process, from material sourcing to final testing, is controlled under our ISO9001 system. Each production batch undergoes rigorous shell and seat pressure tests as stipulated by the CB/T467 standard, with test certificates available upon request. -
Q: What is the typical lead time for an order?
A: Lead times vary based on order quantity, size, and specification. Standard sizes are often available from stock, while custom orders may require production time. We provide accurate lead time estimates with every quotation. -
Q: Do you offer any warranty on your marine gate valves?
A: Yes, we provide a standard warranty against defects in material and workmanship for a specified period under normal service conditions. Detailed warranty terms are provided with our commercial documents. -
Q: Can you provide valves with different trim materials, like stainless steel seats?
A: Yes, material customization is possible. Options like stainless steel trim for enhanced wear resistance in sandy water conditions are available. Please specify your application details for a tailored recommendation.
