As a specialized manufacturer with a strong focus on marine and industrial valve solutions, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CB/T561 Air Bottle Stop Valve. Engineered to meet stringent marine standards, this valve is a critical component for controlling air supply in shipboard air bottle systems. Each unit is supplied with a comprehensive Mill Test Report (MTR) Certification, providing full traceability and verification of material quality and performance, a key requirement for shipbuilders, classification societies, and maintenance operations worldwide.
Our commitment to quality, backed by our ISO9001 certified manufacturing processes established in 2016, ensures that every valve delivers reliable shut-off, excellent durability, and safe operation in demanding marine environments. With an annual export value reflecting our global reach across markets from North America and Europe to Southeast Asia and Africa, we understand the precise needs of the international maritime industry.
Detailed Product Features & Technical Specifications:
- Robust Construction & Material Integrity: Manufactured from high-grade materials such as bronze, stainless steel, or carbon steel, selected for superior corrosion resistance and mechanical strength in saline and humid conditions. The MTR certification details the chemical composition and mechanical properties of the raw materials, ensuring compliance with specified grades.
- Precision Engineering for Secure Sealing: Features a metal-to-metal seat design for bubble-tight shut-off under high pressure. Optional soft seat materials are available for applications requiring zero leakage. The stem is precisely machined and packed to prevent external leakage and ensure smooth operation.
- Versatile Connection & Configuration: Available in various threaded (NPT, BSPT, BSPP) or flanged end connections to suit different piping layouts. Valve configuration (globe, angle, or straight pattern) can be customized based on system design requirements.
- High-Pressure Performance: Designed to handle the high-pressure air stored in marine air bottles. Pressure ratings are customizable, typically capable of withstanding working pressures up to 30 MPa (300 bar), making it suitable for a wide range of vessel types.
- Wide Operational Temperature Range: Engineered to perform reliably across a broad temperature spectrum from -20°C to 200°C, ensuring functionality in both cold and hot engine room environments.
- Manual or Automated Operation: Primarily operated manually via a handwheel, but can be optionally equipped with pneumatic, hydraulic, or electric actuators for remote control and integration into automated systems.
- Compliance with Marine Standards: Manufactured in accordance with the Chinese CB/T561 standard, which is widely recognized and accepted in the shipbuilding industry for air bottle valves.

Frequently Asked Questions (FAQ):
-
Q: What is the significance of the Mill Test Report (MTR) provided with this valve?
A: The MTR is a certified document from the material manufacturer that details the chemical composition, mechanical properties, and heat treatment of the metal used. It provides essential traceability and quality assurance, often required by classification societies and end-users for critical marine applications. -
Q: Is this CB/T561 valve suitable for use with gases other than air?
A: Primarily designed for compressed air systems, it can also be used for inert gases like nitrogen. However, compatibility with other specific gases (e.g., oxygen, hydrocarbons) should be confirmed based on seat material and service conditions. -
Q: Can you provide valves with flanges matching standards other than Chinese standards?
A: Yes, absolutely. We regularly manufacture valves with flanges conforming to international standards such as ANSI, DIN, JIS, and others to meet global project specifications. -
Q: What is the typical lead time for an order of these valves?
A: Lead time depends on order quantity, customization requirements, and material availability. For standard configurations, it typically ranges from 15 to 30 days. We provide accurate timelines upon receipt of your specific inquiry. -
Q: Do you offer any warranty on your CB/T561 Stop Valves?
A: We provide a standard warranty against defects in material and workmanship. The specific warranty period and terms are detailed in our commercial contract and can be discussed based on the application. -
Q: How do I select the correct material (Bronze, Stainless, Carbon Steel) for my application?
A: Material selection depends on the operating environment (corrosiveness), pressure, temperature, and system fluid. Bronze offers good general corrosion resistance, stainless steel is for highly corrosive or clean environments, and carbon steel is for high strength in non-corrosive settings. Our technical team can assist you in making the best choice. -
Q: Are spare parts like gland packings and seals available for future maintenance?
A: Yes, we maintain an inventory of common spare parts and can supply maintenance kits. Providing the valve model and serial number ensures you receive the correct components. -
Q: Can this valve be modified for actuated (automated) operation?
A: Certainly. The valve design can accommodate the installation of pneumatic, hydraulic, or electric actuators. We can supply the complete assembly, including brackets and couplings, as per your control system requirements.
