Product features

The electric cryogenic ball valve is mainly applicable to the low temperature working conditions of liquid nitrogen (cryogenic) media with medium temperature ranging from - 40 ℃ to - 196 ℃. In order to ensure that the valve can operate at low temperature
It operates safely and reliably. The valve parts have been cryogenic treated before finishing. The valve cover adopts a long neck structure, which aims to protect the function of the stuffing box and make the stuffing box
It is located far away from the low temperature to ensure the sealing effect of the packing. The electric cryogenic ball valve is often used in the management system of cryogenic and cryogenic media.

Features of electric low-temperature ball valve:
The electric cryogenic ball valve is applicable to various pipelines. It is used to cut off or connect the medium in the pipeline. Different materials can be used for different temperatures and mediums
The minimum working temperature is - 196 ℃. The medium used is usually liquid helium, liquid hydrogen, liquefied natural gas, liquid nitrogen, liquid oxygen and other cryogenic fluids.
