I. Overview:

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

Applicable temperature range for low temperature safety valves: -196°C to +80°C.

Materials for low temperature valves include: brass, cast steel, carbon steel, stainless steel, chromium-molybdenum steel, etc.

Valve specifications: DN15-DN400.

Pressure: 1.0-32.0 MPa.

Drive methods: manual, automatic.

Standards: National Standard GB HB.

Low temperature valves are widely used in various fields such as chemical industry, papermaking, power generation, liquefied gas, food, pharmaceuticals, mechanical equipment, electronic industry, urban construction, etc.
