As a professional manufacturer of industrial valves, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CB/T4303-2013 Marine Bronze Wafer Double-disc Butterfly Check Valve. Established in 2016 and backed by an ISO9001 certified quality management system, we specialize in producing high-performance valves for demanding applications. This valve is engineered specifically to meet the rigorous standards of marine and shipbuilding industries, offering reliable flow control and prevention of backflow in critical piping systems. With annual exports reaching US$1 Million to US$1.5 Million, our products are trusted by clients across North America, South America, Europe, Asia, Africa, and Oceania.
Product Features and Technical Specifications:
- Premium Bronze Construction: The valve body and key components are manufactured from high-grade bronze, providing excellent corrosion resistance, durability, and suitability for marine environments.
- Wafer Design for Easy Installation: The wafer-style valve is designed to be installed between two pipeline flanges, saving space and simplifying the installation process compared to flanged-end valves.
- Double-Disc Butterfly Mechanism: This design utilizes two sealing discs that close against the flow to prevent reverse flow. It offers a tight seal, low flow resistance when open, and reliable operation.
- Compliance with CB/T4303-2013: The valve is manufactured in strict compliance with the Chinese national standard CB/T4303-2013 for marine valves, ensuring its performance, dimensions, and material requirements meet industry specifications.
- Versatile Application: Primarily designed for marine applications such as seawater systems, ballast systems, cooling systems, and fuel/oil lines on ships and offshore platforms. It can also be used in other industrial systems requiring check valves.
Key Advantages and Customer Benefits:
- Enhanced System Safety: Effectively prevents backflow, protecting pumps, equipment, and ensuring the intended direction of fluid flow in critical systems.
- Long Service Life: The corrosion-resistant bronze material and robust design contribute to a long operational life, reducing maintenance costs and replacement frequency.
- Space-Efficient and Cost-Effective: The wafer design requires less space and often has a lower overall cost compared to equivalent flanged check valves, benefiting system layout and budget.
- Reliable Performance Under Pressure: Designed to perform reliably within its specified pressure range, ensuring consistent operation in variable marine conditions.

Frequently Asked Questions (FAQ):
-
Q: What is the primary advantage of a "wafer" design compared to a flanged design?
A: The wafer design allows the valve to be installed directly between two existing pipeline flanges using bolts, eliminating the need for separate valve flanges. This saves space, reduces weight, and can lower overall installation cost. -
Q: Is this valve suitable for seawater applications?
A: Yes, the bronze material offers good resistance to corrosion from seawater, making it a common choice for marine seawater systems, ballast systems, and cooling systems. -
Q: What does the "Double-disc Butterfly" mechanism mean?
A: It refers to the check valve's closing element: two disc-shaped plates (like butterfly wings) that hinge and close together against reverse flow. This design often provides a more balanced seal and lower flow resistance when open compared to single-disc designs. -
Q: Can this valve be used for oil or fuel lines on ships?
A: Yes, provided the specific oil or fuel is compatible with bronze materials and within the valve's temperature and pressure ratings. It is commonly applied in such systems. -
Q: What pressure ratings are available?
A: The valve is typically manufactured according to pressure classes like PN10 or PN16 as per the standard. The exact pressure rating for a specific size should be confirmed with the manufacturer. -
Q: Are sizes other than the common DN range available?
A> Yes, as a manufacturer, we can often provide custom sizes upon request. Please inquire with your required nominal diameter. -
Q: Does compliance with CB/T4303-2013 imply certification?
A> Compliance means the valve is manufactured to meet the dimensional, material, performance, and testing requirements outlined in that Chinese national standard for marine valves. Our production system is ISO9001 certified for quality management. -
Q: What are the main shipping ports and delivery terms?
A> We primarily ship from Shanghai, Guangzhou, Hongkong, and Beijing ports. Delivery terms (FOB, CIF, etc.) and lead times can be discussed based on your order and destination.
