I. Overview, Application:

Low-temperature safety valves serve as overpressure protection devices in equipment and pipelines. During the manufacturing process, components are immersed in liquid nitrogen at -196°C for 2 to 6 hours, then removed for natural treatment. This cycle 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 used for flammable media require anti-static design.

II. Product Parameter Table:

Operating temperature range of low-temperature safety valves: -196°C to +80°C.

Valve materials include: brass, cast steel, carbon steel, stainless steel, chromium-molybdenum steel, etc.
