Extended Stem Top Entry Cryogenic Ball Valve
Extended Stem Top Entry Cryogenic Ball Valve
The
YFL extended stem cryogenic ball valve is suitable for
service with working temperature down to -196℃ such as
ethylene, LNG, LPG, liquid oxygen, liquid nitrogen, liquid argon, liquid
hydrogen and CO2 .
The materials of YFL cryogenic ball valve for inflammable
and explosive service are very important. If the mechanical characteristic,
strength and rigidity of materials can’t meet the requirements of low
temperature working condition, outside leakage from body and inner leakage from
sealing face will cause explosion.
