進口SMC過濾減壓閥結構原理
下圖是SMC AR平衡式直動式減壓閥結構原理圖。閥芯的下部與二次側壓力相通，故閥芯上下所受氣壓力是平衡的，壓力的變動（不論是一次側還是二次側）不影響閥芯上下氣壓力的平衡，故這種結構形式的壓力特性好。

SMC膜片式減壓閥的工作原理是：將手輪外拉，見到黃色圈后，順時針旋轉手輪，調壓彈簧被壓縮，推動膜片組件下移，通過閥桿，打開閥芯，則進氣口壓力經閥芯節流降壓，有壓力輸出。出口壓力氣體經反饋管浸入膜片下腔，在膜片上產生一個向上的推力。當此推力與調壓彈簧平衡時，出口壓力便穩定在一定值。

逆時針旋轉手輪，調壓彈簧力不斷減小，閥芯逐漸關閉，膜片下腔中的壓縮空氣，經溢流閥不斷從排氣孔排處，直至zui后出口壓力降為零。

調壓完成后，將手輪壓回，手輪被鎖住，以保持設定壓力一定。故稱為鎖定型手輪。

溢流式減壓閥常用于二次側負載變動的場合，如進行頻繁調整的場合、二次側有容器（如氣缸）的場合。在使用過程中，經常要從溢流孔排出少量氣體。當介質為有害氣體的氣路中，為防止污染工作場所，應選用無溢流孔的減壓閥，即非溢流式減壓閥。非溢流式減壓閥也常用于經常耗氣的吹氣系統和氣馬達。
