Vacuum Insulated Shut-off Valve

The Vacuum Insulated Check Valve, namely Vacuum Jacketed Check Valve, is used when liquid medium is not allowed to flow back.

Cryogenic liquids and gases in the VJ pipeline are not allowed to flow back when cryogenic storage tanks or equipment under safety requirements. The backflow of cryogenic gas and liquid may cause excessive pressure and damage to equipment. At this time, it is necessary to equip the Vacuum Insulated Check Valve at the appropriate position in the vacuum insulated pipeline to ensure that the cryogenic liquid and gas will not flow back beyond this point.

In the manufacturing plant, Vacuum Insulated Check Valve and the VI pipe or hose prefabricated into a pipeline, without on-site pipe installation and insulation treatment.
