Medium temperature:-196~200C℃
Cryogenic valves are widely used in petroleum, chemical, air separator, LNG terminal station, and LNG transportation, etc. the cryogenic butterfly valve are available with flange ends, side entry welded type and top entry welded type.
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 resilient seat design, mainly to solve the ordinary material cold contraction, ensure the valve with good sealing performance even when temperature unstable. The valve is bi-direction even in low temperature.It is fire safe.
C. Anti-blow out stem design.
D. Easily maintenance on line.
E. The locking thread to prevent internal stress relaxation.
