    力士樂電磁閥通電后，電磁鐵吸合，動鐵芯上部帶彈簧的密封塊把排氣口關(guān)閉，氣流從進氣口進入膜頭，起到控制作用。

    力士樂電磁閥可以配合不同的電路來實現(xiàn)預(yù)期的控制，而控制的精度和靈活性都能夠保證。

    REXROTH電磁閥是用電磁控制的工業(yè)設(shè)備，是用來控制流體的自動化基礎(chǔ)元件，屬于執(zhí)行器，并不限于液壓、氣動。用在工業(yè)控制系統(tǒng)中調(diào)整介質(zhì)的方向、流量、速度和其他的參數(shù)。

    REXROTH電磁閥由閥體、閥罩、電磁組件、彈簧及密封結(jié)構(gòu)等部件組成，動鐵芯底部的密封塊借助彈簧的壓力將閥體進氣口關(guān)閉。

    當(dāng)力士樂REXROTH電磁閥失電時，電磁力消失，動鐵芯在彈簧力作用下離開固定鐵芯，向下移動，將排氣口打開，堵住進氣口，膜頭氣流經(jīng)排氣口排出，膜片恢復(fù)原來位置。在制氧設(shè)備中，在透平膨脹機進口薄膜調(diào)節(jié)閥的緊急切斷等處有應(yīng)用。

上海維特銳在德國與REXROTH合作，可長期穩(wěn)定供應(yīng)力士樂電磁閥，REXROTH導(dǎo)軌，力士樂柱塞泵等產(chǎn)品
