費斯托減壓閥的分類：按結構形式可分為薄膜式,、彈簧薄膜式、活塞式,、杠桿式和波紋管式,；按閥座數目可人為單座式和雙座式；按閥瓣的位置不同可分為正作用式和反作用式,。費斯托festo先導式減壓閥內部先導式減壓閥當減壓閥的輸出壓力較高或通徑較大時,，用調壓彈簧直接調壓，則彈簧剛度必然過大,，流量變化時,，輸出壓力波動較大，閥的結構尺寸也將增大,。為了克服這些缺點，可采用先導式減壓閥,。先導式減壓閥的工作原理與直動式的基本相同,。先導式減壓閥所用的調壓氣體，是由小型的直動式減壓閥供給的,。若把小型直動式減壓閥裝在閥體內部,，則稱為內部先導式減壓閥；若將小型直動式減壓閥裝在主閥體外部，則稱為外部先導式減壓閥,。與直動式減壓閥相比,，增加了由噴嘴4、擋板3,、固定節(jié)流孔9及氣室B所組成的噴嘴擋板放大環(huán)節(jié),。當噴嘴與擋板之間的距離發(fā)生微小變化時，就會使B室中的壓力發(fā)生根明顯的變化,，從而引起膜片10有較大的位移,，去控制閥芯6的上下移動，使進氣閥口8開大或關小,、提高了對閥芯控制的靈敏度,，即提高了穩(wěn)壓精度。
