Nominal Pressure：4.0MPa
Nominal Diameter: 15mm
Design Temperature：-196℃~+80℃
Suitable Media：LO2、LN2、LAr、LNG、CO2
Body、Cover：CF8
Main Sealing：PTFE
Connection: Thread
Standard: GB/T12241 , GB/T12242，GB/T12243
Our Cryogenic Safety Relief Valve is specially engineered for cryogenic gas applications involving LNG (Liquefied Natural Gas), LN₂ (Liquid Nitrogen), LOX (Liquid Oxygen), LAr (Liquid Argon), and other low-temperature liquefied gases. It provides a reliable and precise pressure release mechanism to prevent overpressure in critical systems.
Built with cryogenic-grade stainless steel or brass, it maintains sealing performance and structural integrity under extreme cold temperatures as low as -196°C.
Wide Pressure Range: Available in various preset pressure levels (e.g., 0.2MPa–2.5MPa) to suit different system needs.
Excellent Low-Temperature Resistance: Works stably in cryogenic conditions without frost buildup or leakage.
Spring-Loaded Mechanism: Ensures immediate response when system pressure exceeds the set point.
Threaded or Flanged Ends: Compatible with most tank, pipe, or vaporizer connections (NPT, BSPT, or custom options).
Leak-Free Design: High-quality valve seat materials ensure tight shutoff and long service life.
This valve is widely used in:
LNG storage tanks and cryogenic cylinders (e.g., Dewars, ISO tanks)
Cryogenic vaporizer skids
Industrial gas pipelines and filling stations
Air separation units (ASU) and gas plants
Liquid oxygen systems in hospitals or aerospace projects
ISO 9001:2015 Quality Management System
Materials meet EN and ASTM cryogenic specifications.
100% factory-tested for leak-tightness and pressure accuracy.
OEM & Customization: We offer logo engraving, pressure setting adjustments, and thread customization.
Fast Delivery: Standard models are ready to ship in 5–10 working days.
Global Experience: Over 30 years exporting to the EU, Middle East, Southeast Asia, and South America.
Technical Support: Engineers available for pre-sale consultation and after-sales guidance.
