GEA AWP止回阀是自动启动的锁定装置。它们通过工作介质施加在阀板上的压力而打开。一旦流量中断或流向反转，阀门就会自动锁定。锁定功能由弹簧的弹力或阀板的自重支撑。GEA AWP止回阀采用夹式设计，适用于安装在工业制冷系统的制冷剂循环中。它们安装在压缩机的压力侧或吸入侧，或安装在只允许一个流动方向的管道中。GEA AWP止回阀无需维护。
阀门功能性能中出现的任何缺陷都可以修复。

The breakthrough that changed spray drying
In 1976, NIRO engineers responded to a competitive challenge by rethinking what spray drying could do. Their idea became the multi-stage dryer MSD. Fifty years later, the same fundamental principle helps turn liquids into the powders used in essential nutrition products and important medicines around the world. Refined through decades of engineering expertise, customer insight and continuous development, MSD is a story of innovation with lasting impact.
