Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, specializes in producing high-quality valves for demanding industrial applications. Our CB/T3191 Marine Ball Valve for Compressed Air Systems is engineered to deliver reliable performance and durability in marine environments and other critical compressed air installations. With an annual export value ranging between US$1 Million and US$1.5 Million, we serve a global clientele across continents including North America, Europe, Asia, and Africa, ensuring our products meet international standards of quality and reliability.
This valve is designed to provide a secure and efficient shut-off solution for compressed air lines, featuring a robust cast iron body and a pressure rating of PN4.0MPa. Its compliance with the CB/T3191 standard underscores its suitability for marine applications, where resistance to corrosion and consistent operation under pressure are paramount. We invite you to explore the detailed specifications and benefits of this valve, designed to enhance the safety and efficiency of your compressed air systems.
Key Features and Technical Specifications:
- Robust Construction: The valve body is made from high-grade cast iron, offering excellent strength and resistance to mechanical stress, ensuring long-term service life in challenging environments.
- Precision Ball Design: The rotating ball mechanism provides a quick and reliable 90-degree turn operation for full opening or closing, minimizing flow resistance and pressure drop in the system.
- Effective Sealing: Equipped with high-quality sealing materials such as PTFE or rubber, the valve ensures leak-tight closure, maintaining system integrity and preventing air loss.
- Versatile Size Range: Available in connection sizes from DN15 to DN100, allowing for integration into various pipeline diameters commonly used in compressed air networks.
- High Pressure Handling: Rated for PN4.0MPa (approximately 40 bar), making it suitable for medium to high-pressure compressed air applications found in industrial and marine settings.
- Marine-Grade Compliance: Manufactured according to the CB/T3191 standard, which specifies requirements for valves used in marine systems, ensuring compatibility and performance in shipboard environments.
- Multiple Operation Options: Can be operated manually via a handwheel or lever, or automated with an optional pneumatic actuator for remote control and integration into automated systems.
- Corrosion Considerations: While the cast iron body provides strength, surface treatments or coatings can be applied upon request to enhance corrosion resistance for specific environmental conditions.

Frequently Asked Questions (FAQ):
-
Q: What does the CB/T3191 standard signify for this valve?
A: CB/T3191 is a Chinese national standard specifically for valves used in marine systems. It defines requirements for materials, design, pressure ratings, and testing to ensure suitability and safety in marine applications, particularly for compressed air services. -
Q: Is this valve suitable only for marine use?
A: While designed and certified for marine environments per CB/T3191, its robust construction and performance characteristics also make it an excellent choice for industrial compressed air systems in factories, power plants, or other facilities requiring reliable medium-pressure valves. -
Q: Can I get this valve in sizes outside the DN15-DN100 range?
A: Our standard production covers the DN15 to DN100 range as listed. For sizes larger than DN100 or smaller than DN15, please inquire about custom manufacturing options, which may be available upon request. -
Q: What are the available end connection types?
A: The standard offering typically includes flanged connections compatible with common pipeline flanges. Threaded connections (e.g., NPT, BSP) are also available as an option. Please specify your required connection type when ordering. -
Q: How does the cast iron body perform in corrosive environments?
A: Cast iron provides excellent mechanical strength. For enhanced corrosion resistance in aggressive environments, surface treatments like epoxy coating or galvanization can be applied. Discuss your specific environmental conditions with our technical team for recommendations. -
Q: Is an automated actuator available for this valve?
A: Yes. While the valve is primarily manual-operated, we can supply compatible pneumatic actuators for automated on/off control. This allows integration into PLC-controlled systems or for remote operation. -
Q: What is the typical delivery time for these valves?
A: For standard sizes and configurations within the DN15-DN100 range, we generally maintain stock for prompt shipment. Delivery times depend on order quantity, destination, and port of shipment (Shanghai, Guangzhou, Hongkong, Beijing). Specific timelines can be provided upon inquiry. -
Q: Does Shanghai Zhibang provide after-sales support or spare parts?
A: Yes. As a manufacturer, we offer technical support, installation guidance, and supply spare parts such as seal kits, balls, or actuators to ensure long-term maintenance of your valves.
