Standards CB/T3191, ISO9001 Manufacturing

As a dedicated manufacturer specializing in marine and industrial valves, Shanghai Zhibang Valve Manufacture Co., Ltd. presents our CB/T3191 Bronze Ball Valve, engineered specifically for reliable bilge pump control and ballast system piping applications. With our ISO9001 certified production processes established since 2016, we focus on delivering valves that combine durability, precise control, and ease of operation—critical factors for marine system safety and efficiency. This valve is designed to withstand the demanding conditions of shipboard environments, offering a robust solution for fluid management.

Core Product Features & Technical Specifications:

Premium Bronze Construction: The valve body is crafted from ASTM B62 bronze, offering excellent corrosion resistance against seawater, bilge water, and other marine fluids, ensuring long service life.
Full Port Design: Provides unrestricted flow with minimal pressure drop, which is essential for efficient bilge pump operation and ballast system filling/draining.
Robust Sealing Mechanism: Utilizes a combination of primary PTFE seals for tight shut-off and a secondary metal-to-metal seal for backup safety, preventing leaks under varying pressures.
Simple & Reliable Operation: Features a manual lever handle with clear open/close positions, allowing for quick and unambiguous control by crew members.
Versatile Connection Options: Available with threaded ends (NPT, BSP) for direct piping integration or optional flanged ends for specific system layouts.
Broad Application Compatibility: Specifically designed per CB/T3191 for marine use, it is suitable for controlling bilge pump discharge lines, ballast tank inlet/outlet piping, and other general seawater service applications onboard vessels.

Frequently Asked Questions (FAQ):

What is the main advantage of using bronze for this ball valve in marine applications?
Bronze, particularly ASTM B62, offers superior corrosion resistance against seawater and bilge fluids compared to many other metals. This significantly extends the valve's lifespan in harsh marine environments, reducing corrosion-related failures.
Can this valve be used for fluids other than seawater or bilge water?
Yes. While designed for marine service, its bronze construction and PTFE seals make it suitable for a range of other non-aggressive fluids like freshwater, oils, and air within its specified temperature and pressure limits.
Is the valve suitable for automated or remote control systems?
This specific model features a manual lever handle. For automated control, we offer optional configurations with pneumatic or electric actuators. Please inquire for actuator-compatible versions.
How does the CB/T3191 standard relate to other international valve standards?
CB/T3191 is a Chinese national standard specifically for marine bronze valves. It defines requirements for materials, dimensions, pressure ratings, and testing, ensuring reliability for shipboard use. It aligns with common functional requirements seen in marine applications globally.
What is the typical delivery lead time for these valves?
Lead times vary based on order quantity and specific configuration (size, connection type). Standard items from our inventory can often be shipped promptly. We provide estimated lead times upon order confirmation, leveraging our efficient logistics from multiple Chinese ports.
Are spare parts like seals or handles available for purchase?
Yes. We supply replacement seal kits and other components to support maintenance. Using original spare parts ensures optimal performance and longevity.
Can the valve be installed in any orientation?
Yes, ball valves generally can be installed in any orientation (horizontal, vertical, etc.) without affecting their operation or sealing capability, which simplifies piping layout.
What pressure testing is performed on these valves before shipment?
Each valve undergoes pressure tests according to standard procedures to verify its sealing integrity and strength at the rated pressure (PN16). Our ISO9001 system ensures consistent quality control throughout manufacturing.
