Cryogenic Check Valve

The cryogenic check valves designed by us are suitable for working temperature of -196 ℃. By adopting the most advanced design concept, high precision processing control and strict process management, the ultra-low temperature valve has many outstanding advantages, such as reliable sealing, high stability at low temperature and long service life, etc. Products are widely used in liquefied natural gas, liquefied petroleum gas, air separation and other low-temperature industries.
