Technical Specifications for -196 Degree Celsius Cryogenic Service
DN15-80 cryogenic safety valves typically feature stainless steel body construction, available in threaded, flanged, or welded connections . Pressure ratings range from PN16 to PN64 (0.1-6.4MPa) . Set pressure is adjustable from 0.1MPa upward to meet system requirements . Applicable standards include GB/T 29026-2012 for cryogenic safety valves, GB/T 40011-2021 for pilot operated cryogenic safety valves, and the new GB/T 46630-2025 for cryogenic vessel safety valves .
Factory Direct Advantages
Purchasing directly from manufacturers such as Yongyi Valve Group, Fangding Cryogenic Valve, or Minjia Valve provides cost savings, direct technical support, and fully certified products with Chinese safety licenses (TS) . For international standards, HEROSE offers global approvals including ASME, CRN, and CE .
Selection Considerations
When specifying a cryogenic safety valve, verify temperature rating matches the minimum service temperature. Confirm material compatibility with your specific cryogenic media. Select appropriate connection type and pressure rating. For LNG or critical cryogenic applications, specify NACE compliance and request full Material Test Reports .
Summary
-196 degree Celsius cryogenic safety valves are essential for liquid nitrogen, oxygen, argon, and LNG service. Factory direct pricing starts from approximately $130 USD for DN25 configurations and reaches over $4,400 CNY for larger sizes. Certification per GB/T 29026-2012, GB/T 46630-2025, or international standards ensures safe and reliable operation. Selection requires careful evaluation of pressure rating, connection type, and material compatibility based on specific cryogenic service conditions.
