CHAODA valves group is specialized in manufacturing Cryogenic Floating Ball valve with following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc.
Cryogenic valves include all types of cryogenic ball valve, cryogenic gate valve, cryogenic globe valve, cryogenic safety valve, cryogenic check valve, cryogenic butterfly valve, cryogenic needle valve, cryogenic throttle valve, cryogenic pressure reduce valve and so on. Cryogenic floating ball valve is used for ethylene, LNG device, LPG storage tank, Stellite station, Air seperation equipment, tail gas separation device for petroleum & chemical, storage tank and lorry for low temperature medium as liquid oxygen, nitrogen, argon and carbon dioxide and some oxygen generation devices.
All the main components of Steel Cryogenic Floating ball valve developed by CHAODA would be treated in cryogenic treatment medium for 2~6 hours to release the material stress after raw machining to ensure its stability under cryogenic condition. Precise manufacturing dimension should be guaranteed to ensure no leakage from the deformation caused by the temperature changing.
Cryogenic Floating Ball valves(Generally flanged connection, but butt-welding is optional) are suitable for use on various kinds of pipeline from Class150 To Class900, PN16 To PN100 to cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Manual/worm gear/pneumatic or electric actuators could be chosen by needs.
The seat of Cryogenic floating ball valve always uses PTFE with 25% Glass reforced or PEEK. PTFE+25% glass reforced is generally used for 800LB for its better performance than PTFE and more better corrosion-resistant feature.
The body of Cryogenic floating ball valve should have strong rigidity to ensure no deformation of the seat ring part as the body would bear large extra stress of low-temperature stress, expansion and contraction. Angle or groove should be avoided on the valve body to prevent the damage caused by the concentration of low temperature stress.
