德國力士樂節流和單向節流閥是氣流只能一個方向流動而不能反向流動的方向控制閥。其工作原理與液壓單向閥一樣。壓縮空氣從P口進入，克服彈簧力和摩擦力使單向閥閥口開啟，壓縮空氣從P流至A；當P口無壓縮空氣時，在彈簧力和A口(腔)余氣力作用下；閥口處于關閉狀 態，使從A至P氣流不通。單向閥應用于不允許氣流反向流動的場合，如空壓機向氣罐充氣 時，在空壓機與氣罐之間設置一單向閥，當空壓機停止工作時，可防止氣罐中的壓縮空氣回流到空壓機。單向閥還常與節流閥、順序閥等組合成單向節流閥、單向順序閥使用。4WE6D62/EW230N9K4 4WE6D52/OFBW110RNEX 4WE6D52/BW110RNEX 4WE6D62/6EG24VN9K4
