The cryogenic swing check valves designed by Maverick 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.
Cryogenic series valves are offers safe, prevents frost or ice formation around the packing box area and minimizes heat transfer in the operating fluid itself. specially designed for the production, storage and transport of liquefied gases such as oxygen, nitrogen, LNG, argon and helium, etc. All cryogenic swing check valves are produced with extended bonnet, enclosed vapour chamber to keep the stem packing exposed only to vapour, and thus ensuring proper function.
