Application conditions：

Medium temperature:-196~200C℃

Cryogenic valves are widely used in petroleum,chemical, air separator, LNG terminal station, and LNG transportation, etc. The cryogenic ball valve are available with top entry and side entry.

Product characteristic：

A. For stem packing, three-multiple sealing structure are used for cryogenic application. It is effective and reliable, meeting the low leakage requirement.

B. The patent technology of "elastic compensation structure seat design" to make the seat and metal bellow to a integrate, eliminates the valve seat and valve seal leak. When pressure is rising, the seat sealing will pressing the ball more tightly to guarantee the reliable seal in low temperature conditions.

C. Anti-blow out stem design.

D. MNPSultiple pressure relief to prevent abnormal cavity pressure.

E. Rapid dismounting function for easily maintenance on the field.
