Manufacturer Of Cryogenic Ball Valve Q471x - China

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.
