Cryogenic Ball Valve

Cryogenic Ball Valve
Characteristic：
In order to prevent packing seal invalidation of stem in the low temperature condition, we adopt long-necked design in the low temperature valve. In order to avoid the cavity pressure rise, we Install self-release pressure structure on seat to prevent medium temperature rising. Strictly controlling the material’s chemical element and impact toughness in low temperature.
