Cryogenic Ball Valve
The cryogenic ball valve is applicable to different pipeline.By adopting different materials, the cryogenic ball valve is applicable to different working temperature and medium.The minimum temperature for the ball valve is -196 Degree C . The operation of the ball valve can be manual operated, gear operated, pneumatic operated and motor operated. The end connection usually is flanged ends. However, the welded ends are also optional.
The cryogenic ball valve has two types: floating ball and trunnion mounted ball. For their range, face to face dimension and flange dimension, please refer to the corresponding data of common floating ball valve and trunnion mounted ball valve. For valves with working temperature above -50 Degree C, long neck design is seldom adopted. For valves with working temperature below-50 Degree C, the neck length T shall be 250mm, or shall be decided as per our own design and calculation.
