Extended bonnet cryogenic ball valve introduction
Extended bonnet cryogenic ball valve is suitable for the management system of cryogenic liquid storage and transportation equipment. Extended bonnet cryogenic ball valve has the characteristics of flexible switch and reliable seal, and Extended bonnet cryogenic ball valve can also be used for other management systems of cryogenic and cryogenic medium.Extended bonnet cryogenic ball valve is mainly used for the output of liquid low-temperature media such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products and other low-temperature media.Extended bonnet cryogenic ball valve is suitable for the pipeline, used to cut off or connect the medium in the pipeline, with different materials, can be applied to different temperatures and media, the minimum working temperature is -196℃.Flange floating cryogenic ball valve for manual, worm drive, pneumatic or electric. Extended bonnet cryogenic ball valve generally uses flange connection, also may use the welding connection.

Extended bonnet cryogenic ball valve working principle 
Extended bonnet cryogenic ball valve after low-temperature cryogenic treatment, rough machining parts in the cooling medium for several hours (12 hours), in order to release the stress, ensure the low-temperature performance of materials, ensure the processing size, to prevent the valve in low-temperature working conditions, deformation caused by temperature change and leakage.
