YFL Low temperature swing check valves made in material of stainless steel CF8 are used for LNG pipe line at temperature of -194 degree C.

YFL Cryogenic swing check valves are exported to Spain for LNG transportation station.

The mechanical parts of these stainless steel CF8 swing check valves are done with low temperature  treatment before assembly.

After assembly, the cryogenic swing check valves are done with pressure test and seal test under -194 degree C. These cryogenic swing check valves passed the low temperature valve tests successfully.
