力士樂分步直動(dòng)式電磁閥：
原理：REXROTH電磁閥是一種直動(dòng)和先導(dǎo)式相結(jié)合的原理,，當(dāng)入口與出口沒有壓差時(shí)，通電后,，電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次向上提起，閥門打開,。當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí)，通電后,，力士樂電磁閥電磁力先導(dǎo)小閥,，主閥下腔壓力上升,，上腔壓力下降,，從而利用壓差把主閥向上推開,；斷電時(shí)，先導(dǎo)閥利用彈簧力或介質(zhì)壓力推動(dòng)關(guān)閉件,，向下移動(dòng)，使閥門關(guān)閉,。
特點(diǎn)：REXROTH力士樂電磁閥在零壓差或真空、高壓時(shí)亦能可*動(dòng)作,，但功率較大，要求必須水平安裝,。
REXROTH電磁閥液壓裝置中容易產(chǎn)生噪聲的元件一般認(rèn)為是泵和閥，閥中又以溢流閥和電磁換向閥等為主,。產(chǎn)生噪聲的因素很多。
力士樂REXROTH電磁閥的噪聲有流速聲和機(jī)械聲二種,。流速聲中主要由油液振動(dòng),、空穴以及液壓沖擊等原因產(chǎn)生的噪聲。機(jī)械聲中主要由閥中零件的撞擊和磨擦等原因產(chǎn)生的噪聲。
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
