Cryogenic Ball Valve
Cryogenic ball valves are suitable for low-temperature and ultra-low temperature conditions: LNG, air separation, ethylene rapid cooling cracking gas, ethylene distillation, and low-temperature methanol washing processes. Long neck valve cover structure: ensures the sealing performance of the packing box and protects it from freezing. Automatic pressure relief valve seat: avoids abnormal pressure rise in the middle chamber- 196 ℃ liquid nitrogen cryogenic treatment: transforms residual austenite into martensite, enhancing dimensional stability.
