Product Description
Cryogenic valves are very similar to conventional valves, with the exception of materials and features such as an extended stem. These extended stems allow handles or actuators to be at an ambient temperature.
Cryogenic valves normally refer to valves with working temperature below -110°C, widely used in industrial gas, LNG, LPG and other low temperature applications and regulating or controlling the flow of cryogenic gases, slurries or liquids at low temperatures. These valves come in different shapes and sizes so that they can handle different pressures required by various applications. Some of the common types of cryogenic valves are butterfly valves, relief valves, ball valves and globe valves. The user can manually operate or automate cryogenic valves to handle large systems.

Notes When Use
1 . It should ensure that the pipe is blown clean before installation.
2 . When installing, make sure that the flow direction indicated by the arrow on the valve body should be consistent with the flow direction of the fluid.
3 . This valve has been degreased. Store and keep clean when installing.
4 . After the pipeline construction is completed, all the valves on the pipeline should be opened, and the residue in the pipeline should be thoroughly and thoroughly kept to ensure that the pipeline system is clean and free of debris.
5 . The installation system diagram with the oil-free requirements should be degreased.
6 . Slowly open and close during use.
7 . If the precision parts such as the valve disc, valve seat and valve stem are worn or damaged, it must be repaired and replaced in time.
8 . For parts such as gaskets and sealing materials, replace them with new ones each time.
