MAIN FEATURES
Cryogenic ball valve is suitable for service of working temperature down to -196ºC, such as LNG, LPG, and air separation industry. The cryogenic trunnion ball valves are produced by the most advanced technology. It is designed with LIP SEAL which can keep valves with excellent sealing performance in ultra-low temperature. Wuzhou cryogenic test laboratory can test valves up to NPS32.
