  • Pneumatic cryogenic ball valve Featue

    Pneumatic cryogenic ball valve is special ball valve for the medium with its temperature from -40 ° C to -196 ° C. Cryogenic ball valve with pneumatic actuator can be used for cryogenic fluids, such as liquefied natural gas, liquid nitrogen, liquid oxygen, and liquid argon,etc.

    Pneumatic cryogenic ball valve is subjected to special cryogenic treatment to ensure the cryogenic performance of the material. When operating in cryogenic conditions, it will not cause deformation and leakage due to temperature changes.The bonnet of Pneumatic cryogenic ball valve adopts a extended design structure, and its purpose is to protect the function of the packing box, so that the packing box is located far away from the cryogenic temperature to ensure the sealing effect of the packing.
