As a professional valve manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing high-performance, reliable fluid control solutions for the global marine industry. Our CB/T467-1995 Bronze Gate Valve is engineered specifically for critical applications such as ship engine cooling line installations, where failure is not an option. Built to withstand the harsh marine environment, this valve ensures precise flow control, long service life, and minimal maintenance, protecting your vessel's most vital systems. With nearly a decade of manufacturing expertise since our establishment in 2016, we understand the stringent demands of marine engineering and deliver products that meet and exceed industry standards. Our valves are trusted by shipyards and operators worldwide, from North America and Europe to Southeast Asia and Africa, facilitating smooth operations across oceans.
Product Features & Technical Advantages:
- Superior Corrosion Resistance: Manufactured from high-grade bronze alloys (typically CuZn), these valves offer exceptional resistance to seawater, brackish water, and the corrosive elements commonly found in marine cooling systems. This material choice prevents galvanic corrosion and ensures integrity over extended periods.
- Robust Construction & Design: The valve body, bonnet, gate, and stem are precision-machined for a perfect fit. The full-bore design minimizes pressure drop across the valve, ensuring efficient coolant flow to the engine, which is crucial for optimal thermal management and engine performance.
- Reliable Sealing Performance: Features a wedge gate design that provides a tight, bubble-tight seal when fully closed, preventing leakage in the cooling circuit. The sealing surfaces can be metal-to-metal or incorporate resilient materials for enhanced shut-off capabilities.
- Durability in Demanding Conditions: Designed to handle the vibration, shock, and thermal cycling inherent in ship engine rooms. The stem is securely packed with high-quality gland packing (e.g., graphite) to prevent stem leakage and allow for easy adjustment.
- Versatile Operation & Installation: Available with a standard handwheel for manual operation or can be fitted with gear operators for larger sizes or high-torque applications. Offers multiple end connection options to seamlessly integrate into existing piping systems conforming to various international standards.
- Compliance & Traceability: Strictly manufactured in accordance with the Chinese Ship Standard CB/T467-1995, which specifies materials, dimensions, pressure ratings, and testing requirements for marine bronze gate valves. This ensures compatibility and reliability for shipbuilding and repair.

Frequently Asked Questions (FAQ):
-
Q: What does the "CB/T467-1995" standard signify for this valve?
A: CB/T467-1995 is a specific Chinese national standard ("Chuan Biao" or Ship Standard) that governs the design, material, manufacturing, testing, and acceptance criteria for bronze gate valves used on ships. Valves conforming to this standard are recognized as suitable for marine applications. -
Q: Why is bronze the preferred material for ship engine cooling valves?
A: Bronze, particularly tin bronze or leaded brass, offers an excellent balance of strength, machinability, and most importantly, high corrosion resistance to seawater. It also has good anti-galling properties, making it ideal for valve components in contact with seawater. -
Q: Can this valve be used with fluids other than seawater in the cooling system?
A: Yes. While designed for seawater, it is also suitable for fresh water, lubricating oils, and air within its specified temperature and pressure ratings. Always confirm the medium compatibility for your specific application. -
Q: Are these valves suitable for both main engine and auxiliary engine cooling lines?
A: Absolutely. The valve's design and pressure ratings cover a wide range of applications within a vessel's cooling water system, including lines for main propulsion engines, generator sets, and other heat exchangers. -
Q: What are the available actuation options if manual operation is not desired?
A: While supplied as standard with a handwheel, these gate valves can be configured to accommodate electric, pneumatic, or hydraulic actuators. The valve design includes a standardized mounting interface for such add-ons. -
Q: How do you ensure quality control during manufacturing?
A: Our production follows a strict quality management system certified to ISO9001. Each valve undergoes rigorous testing, including hydrostatic shell tests and seat leakage tests, as per the CB/T467-1995 standard. Material certificates are available upon request. -
Q: What is the typical lead time for an order?
A: Lead time varies based on order quantity, size, and specification. Standard sizes and configurations typically have shorter lead times. We provide accurate delivery estimates upon receipt of your detailed inquiry. -
Q: Do you offer customization for non-standard pressure ratings or connections?
A: Yes. As a manufacturer, we have the capability to customize valves to meet specific project requirements, including special pressure classes, end connections, or material grades, subject to technical review.
