Electric actuated cryogenic ball valve introduction
Electric actuated cryogenic ball valve is suitable for medium temperature -40℃ ~ -196℃,cryogenic ball valve is called low temperature ball valve,Electric actuated cryogenic ball valve is mainly used for ethylene, liquefied natural gas (LNG) plant, gas LPG, LNG storage tanks to accept base and goonhilly, air separation equipment, oil chemical tail gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide cryogenic storage tank and tank lorry, psa oxygen generating device, etc.The output of liquid low-temperature media such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, not only flammable and explosive, but also in the heating to gasification, gasification, the volume expansion of hundreds of times.

Electric actuated cryogenic ball valve performance
Size: 1/2 ~ 24 "(DN15 to 24"))
Pressure grade: 150~1500LB(PN16~PN250)
Connection: Flanged, welded, threaded.
Cryogenic ball valve materials: LCB, LC3, CF8.
Working temperature: -46℃, -101℃, -196℃.
Applicable medium: liquefied natural gas, ethylene, propylene, etc.
Driving mode: manual,gear, bevel gear, electric,pneumatic.

Electric actuated cryogenic ball valve characteristics:
1. An extended bonnet to the cryogenic ball valve can make the packing gland in the valve and the actuator further away from the cold process so the valve can open and close properly, protect it from freeze-damage caused by low temperature fluid.
2. Low operating torque for smoother operations.
3. Excellent seat and seal design minimizes leakage.
4. Fire-safe design.
5. Rigid body construction minimizes thermal shrinkage.
6. By adopting different materials, the cryogenic ball valve is applicable to different working temperature and medium. The minimum temperature for the ball valve is -196ºC. 

Electric actuated cryogenic ball valve Material selection
The material of liquefied natural gas valve is very important, the material is not qualified, will cause the outer leakage or inner leakage of the shell and sealing surface;The comprehensive mechanical properties, strength and steel degree of the parts can not meet the use requirements or even fracture.Causes the liquefied natural gas medium to leak causes the explosion.Therefore, in the development, design and development of liquid natural gas valve process, material is the primary key problem.Valve body and bonnet: LCB(-46℃), LC3(-101℃), CF8 (304) (-196℃).

Electric actuated cryogenic ball valve Low temperature treatment
Our factory to the production of Electric actuated cryogenic ball valve through special low-temperature treatment, the rough machining parts in the cooling medium for several hours (2-6 hours), to release the stress, to ensure the low-temperature performance of materials, to ensure the precision machining size, in case of the valve in low-temperature working conditions, caused by temperature deformation caused by leakage.
