Consideration of microstructure, the metal material has a face-centered cubic lattice of the austenitic steel, Reducing Valves copper and aluminum do not appear in the low temperature low temperature brittleness, but the hardness of aluminum and aluminum alloys is not high, the sealing surface of the wear-resistant aluminum , anti-scratch performance is poor, so the use of low-temperature valves have certain limitations, only used in low voltage and small-caliber valve.

从金相考虑，金属材料中具有面心立方晶格的奥氏体钢、铜和铝在低温状态下不会出现低温脆性，但因铝及铝合金的硬度不高，铝密封面的耐磨、耐擦伤性能差，所以在低温阀门中的使用有一定的限制，仅用于低压和小口径阀门中。
