I. Overview:

Cryogenic safety valves are mainly used in low-temperature liquid medium systems such as liquid oxygen (liquid nitrogen, liquid argon). They feature smooth activation, reliable sealing, and stable popping pressure.

Specifications:
Applicable Media: LO2, LN2, LAR, LNG, etc.
Applicable Temperature: -196°C to +80°C

Materials: Body, Seat: Copper/Stainless Steel

Disc, Stem, Spring: Stainless Steel

II. Overview:

Cryogenic safety valves serve as overpressure protection devices for equipment and pipelines. During manufacturing, parts are immersed in liquid nitrogen at -196°C for 2 to 6 hours, then removed for natural treatment. This process is repeated twice to minimize deformation caused by temperature differences and changes in metallographic structure, enhancing the valve's sealing performance at low temperatures. Valves for flammable media require anti-static design.
