Low temperature globe valves usually refer to working temperature below 110 ℃. They are widely used in liquefied natural gas, liquefied petroleum gas and other industries in low temperature. From 2008, globe valves used below 196 ℃ can be made, all the parts through liquid nitrogen low temperature pretreatment, that completely avoid the seals deformation and leakage in the process.
