cryogenic control valve description 

Cryogenic control valve ,seat oriented with unbalanced trim structure to provide excellent dynamic stability and seat seal performance. Under cryogenic conditions, it is not affected by the low-temperature medium and effectively guarantees the absolute sealability and stable operation sensitivity of the valve stem, Body and related materials are made of stainless steel or aluminum-magnesium alloy, which is resistant to cryogenic temperatures, ensuring the strength of the valve body in cryogenic conditions, Valve stem seals can be double bellows sealed and standard stuffing box seals, The unbalanced quick-release internal trim structure makes cryogenic valves extremely convenient for on-line maintenance. According to working conditions, you can choose balanced internal parts, or special internal parts such as noise reduction and anti-cavitation. (Please refer to the relevant internal structure control valve for specific internal parts description).
