Cryogenic Lift Check Valve Series

Valve overview:
Cryogenic check valves are mainly used in low-temperature storage tanks, tank cars and skid-mounted pipelines, and have the characteristics of preventing medium backflow and reliable sealing
Executive standard:
Design standard: GB/T24925-2019
Normal temperature sealing performance: GB/T26180-2011
Low-temperature sealing performance: G/T24925-2019
Installation and maintenance matters
When installing the valve, it should be noted that the flow direction of the valve mark should be consistent with the flow direction of the medium
Make sure the pipes are blown clean before installation
The valve core should be taken out during welding
After the pipeline installation is completed, open all valves and purge repeatedly to ensure that the pipeline is clean and free of residual impurities
It is recommended to use dry nitrogen or compressed air for pressure tests. It is strictly forbidden to use a low-temperature medium after a hydrostatic test.
