As a specialized manufacturer with a focus on precision fluid control, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our High-Pressure Air Bottle Stop Valve, Model CB/T561. Engineered for demanding applications, this valve is designed to provide reliable shut-off control in systems operating at up to 30 Bar working pressure. Built to the exacting specifications of the CB/T561 standard, it represents our commitment to delivering robust, high-performance components for the global industrial market. With years of experience serving diverse regions from North America to Southeast Asia, we understand the critical need for safety and durability in high-pressure environments.
This valve is a cornerstone component for systems requiring secure and immediate isolation of compressed air or gas. Its design prioritizes operator safety and system integrity, making it suitable for a wide range of industrial and commercial settings.
Detailed Features and Technical Advantages:
- Pressure-Rated Design: Specifically engineered and tested for a 30 Bar (435 PSI) working pressure, ensuring safe operation within its designated range and providing a reliable safety margin.
- Standard Compliance: Manufactured in strict adherence to the CB/T561 standard, guaranteeing dimensional accuracy, material quality, and performance consistency that meets recognized industry benchmarks.
- Robust Construction: Typically constructed from high-grade brass or stainless steel, offering excellent corrosion resistance and mechanical strength to withstand the rigors of high-pressure service.
- Secure Sealing Mechanism: Incorporates a precision-machined sealing system, often utilizing durable elastomers like NBR (Nitrile Butadiene Rubber), to ensure a bubble-tight seal in both open and closed positions, preventing costly leaks.
- User-Friendly Operation: Features a manual handwheel or lever designed for positive, unambiguous operation. The design allows for quick and easy opening/closing, facilitating efficient system control and maintenance procedures.
- Versatile Application Scope: Primarily designed for high-pressure air bottles and receivers, but also suitable for various compressed gas systems, pneumatic control panels, industrial machinery, and testing equipment.

Frequently Asked Questions (FAQ)
Q1: Is this valve suitable for use with gases other than air?
A: While designed for compressed air systems, it can often be used with other inert gases like nitrogen. However, compatibility depends on the seal material. Please specify the gas medium when inquiring so we can recommend the appropriate seal material (e.g., NBR for air, FKM for certain chemicals).
Q2: What are the standard thread connections available for this CB/T561 valve?
A: We typically offer common industrial threads such as NPT (American National Pipe Taper) and BSP (British Standard Pipe) in both parallel (BSPP) and tapered (BSPT) variants. The specific connection is customizable based on your system requirements. Please provide your thread specification when ordering.
Q3: Does the 30 Bar rating refer to the maximum pressure the valve can handle?
A: The 30 Bar is the designated Nominal Working Pressure (PN). This is the continuous operating pressure for which the valve is designed. Valves are typically factory tested at a higher pressure (e.g., 1.5x PN) as a safety proof test. Always operate within the rated working pressure for safety and longevity.
Q4: Can you provide valves with different pressure ratings, like 40 Bar or 20 Bar?
A: Yes, we manufacture stop valves to various pressure ratings and standards. While this specific model is rated for 30 Bar per CB/T561, we can produce valves tailored to other pressure requirements. Please contact us with your specific needs for a customized solution.
Q5: What is the lead time for an order of these valves?
A: Lead times vary based on order quantity, customization, and current production schedule. For standard configurations, we often have stock or can produce within a few weeks. We provide estimated lead times with every quotation to help you plan your project.
Q6: Are certifications or test reports provided with the valves?
A: As an ISO9001 certified manufacturer, we conduct in-house quality checks. Standard material certificates and our internal inspection reports can be provided. Specific third-party certifications (if required) may be available upon request and may involve additional time and cost.
Q7: What is the main difference between a "stop valve" and other valve types like ball valves or check valves?
A: A stop valve (or isolation valve) is designed primarily for on/off service to completely open or close the flow path. It is not for flow regulation. Ball valves offer quick quarter-turn operation, while check valves allow flow in only one direction automatically. This CB/T561 valve is a manual stop valve ideal for securely isolating a high-pressure air source.
Q8: Do you offer any warranty on your valves?
A: We stand behind the quality of our products. We offer a standard warranty against defects in materials and workmanship under normal use conditions as per our terms and conditions. Specific warranty details are provided with the commercial invoice.
