Low Temp (Cryogenic) Ball Valve with Pneumatic Actuator, Extended Bonnet

Low temp (Cryogenic) ball valve is special ball valve for that medium using its temperature from -40 C to -196 C. Cryogenic ball valve with pneumatic actuator can be used as cryogenic fluids, for example liquefied gas(LNG), liquid nitrogen (LN2), liquid oxygen (LOX), and liquid argon (LAr), etc.The pneumatic cryogenic ball valve is exposed to special cryogenic treatment to guarantee the cryogenic performance from the material. When operating in cryogenic conditions, it won't cause deformation and leakage because of temperature changes.The bonnet of cryogenic pneumatic ball valve adopts a extended design structure, and it is purpose would be to safeguard the part from the packing box, so the packing box is situated far from the cryogenic temperature to guarantee the sealing aftereffect of the packing.
