Nominal Pressure：4.0MPa
Design Temperature：-196℃~+80℃
Suitable Media：LNG、LO2、LN2、LAr、CO2
Body：CF8
Spring：S30210
Main Sealing：Carbide
This DN25 cryogenic safety relief valve features a hard metal seat design, providing superior sealing, long service life, and resistance to wear under ultra-low temperature conditions. Designed for LNG, LN₂, LOX, and other cryogenic gas systems, the valve protects tanks, pipelines, and vaporizers from dangerous overpressure events.
Made from high-grade stainless steel, the DN25 valve operates reliably at temperatures as low as -196°C. Its spring-loaded structure delivers quick response and consistent pressure relief.
Key applications include cryogenic storage tanks, gas filling stations, LNG transport systems, and air separation units.
Features:
DN25 port size (1”)
Hard seal (metal seat) structure for leak-free operation
Set pressure range: 0.2 – 2.5 MPa (adjustable)
CE & ISO certified
OEM logo and custom pressure settings available
Available with threaded or flanged connections
This valve is ideal for industries that demand precision, durability, and cryogenic-grade safety.
