What Are The Functions of Cryogenic Ball Valves?
The DBV cryogenic ball valves is suitable for all kinds of pipelines, used to cut off or connect the medium in the pipeline. It can work under ultra-low temperature and the worst environmental conditions, the lowest temperature is -196 ℃, and the medium used is usually liquid helium, liquid hydrogen, liquefied natural gas, liquid nitrogen, liquid oxygen and other cryogenic fluids. It has reliability and stability, and its main features are its compact structure, easy operation and maintenance, suitable for general working media such as water, solvent, acid and natural gas, and also suitable for medium with harsh working conditions, such as oxygen, hydrogen peroxide, methane and vinyl etc. The main thing is to ensure safety and can be used in air separation plants, LNG storage and transportation and in the aviation, petrochemical and pharmaceutical industries.
When operating in low temperature conditions, there will be no leakage due to deformation caused by temperature changes. The bonnet of the pneumatic low temperature ball valve adopts a extended stem structure.
