Definition of Cryogenic Needle Valve

A cryogenic needle valve refers to a needle valve applicable to fluids such as liquefied gases, including LO2 (liquid oxygen), LN2 (liquid nitrogen), LAr (liquid argon), LNG (liquefied natural gas), LC2H4 (liquid ethylene), ethylene, liquid hydrogen, liquid ammonia, liquid propane, and liquefied petroleum gas. Imported cryogenic needle instrument valves share the same structural form as globe valves, feature an extended stem design, and can withstand a low temperature of -196℃.

Product Characteristics of Cryogenic Needle Valve

Lowest temperature application: The metal material maintains the mechanical properties required for working conditions at low temperatures.

Possesses impact toughness, relative elongation, and structural stability.

Features good wear resistance under low-temperature and oil-free lubrication conditions.

Has good corrosion resistance.

When using welded connections, the weldability of the material also needs to be considered.
