Product Description
Product Overview
This cryogenic one-way check valve is specifically designed for LO2, LN2, and other cryogenic media applications. Featuring a flange connection and CF8 body construction, it ensures reliable performance in extreme temperature environments from -196°C to +80°C.
Operating Principle
The valve operates on a simple yet effective principle: when medium flows in the designated direction, the valve disc opens automatically. During reverse flow, the combined force of the valve disc weight and medium pressure creates a tight seal against the valve seat, effectively preventing backflow.
Key Features
- Stainless steel sealing surfaces for superior durability
- CF8 valve body construction for cryogenic applications
- Flange connection design for secure installation
- Compliant with GB/T24925-2010 design standards
- Suitable for LO2, LN2, LAr, LNG, LCO2 media
- Operating temperature range: -196°C to +80°C
- Nominal pressure rating: PN32MPa

Customization & Ordering
We offer comprehensive customization options. For custom orders, please provide detailed specifications including structure length, connection type, nominal diameter, media type, temperature/pressure range, and testing requirements. Custom valves typically require 30-45 days for production, while stock items ship within 5 days.
Installation & Usage Guidelines
- Ensure piping is thoroughly cleaned before installation
- Install with flow direction arrow aligned with fluid flow
- Maintain cleanliness during installation (valves are pre-degreased)
- Flush entire system after installation to remove debris
- Operate valves slowly during opening and closing
- Replace worn components (disc, seat, stem) promptly
- Always use new gaskets and sealing materials
