德國FESTO減壓閥，FESTO過濾減壓閥
FESTO過減壓閥正常工作，配用的執行機構要能產生足夠的輸出力來保證高度密封和閥門的開啟。 
對于雙作用的氣動、液動、電動執行機構，一般都沒有復位彈簧。作用力的大小與它的運行方向無關，因此，選擇執行機構的關鍵在于弄清zui大的輸出力和電機的轉動力矩。對于單作用的氣動執行機構，輸出力與閥門的開度有關，調節閥上的出現的力也將影響運動特性，因此要求在整個調節閥的開度范圍建立力平衡。

FESTO過減壓閥是保護油罐安全的重要附件，裝設在油罐的頂板上，由壓力閥和真空閥兩部分組成。它的作用在一般情況下，保持油罐的密閉性，在一定程度上減少油品的蒸發損耗。而在必要時，能自動通氣調節平衡油罐內外壓力，對油罐起到安全作用。當罐內油氣壓力大于油罐允許壓力時，油蒸汽經壓力閥外逸，此時真空閥處于關閉狀態；當罐內油氣壓力小于油罐允許真空度時，新鮮空氣通過真空閥進入罐內，此時壓力閥處于關閉狀態，允許壓力（或真空壓力）靠調節盤的重量來控制。

FESTO過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。
 
圖14—2所示為內部先導式減壓閥的結構圖，與直動式減壓閥相比，該閥增加了由噴嘴4、擋板3、固定節流孔9及氣室B所組成的噴嘴擋板放大環節。當噴嘴與擋板之間的距離發生微小變化時，就會使B室中的壓力發生根明顯的變化，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，即提高了穩壓精度。
