    力士樂電磁閥閥體全不銹鋼,；對于強腐蝕的介質(zhì)必須選用隔離膜片式,。中性介質(zhì)，也宜選用銅合金為閥殼材料的電磁閥,，否則，閥殼中常有銹屑脫落,，尤其是動作不頻繁的場合,。氨用閥則不能采用銅材,。

    力士樂電磁閥爆炸性環(huán)境：必須選用相應防爆等級產(chǎn)品,，露天安裝或粉塵多場合應選用防水,，防塵品種,。

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

力士樂先導式電磁閥：
    原理：通電時,，電磁力把先導孔打開,，上腔室壓力迅速下降，在關(guān) 閉件周圍形成上低下高的壓差,，流體壓力推動關(guān)閉件向上移動,，閥門打開；斷電時,，彈簧力把先導孔關(guān)閉,，入口壓力通過旁通孔迅速腔室在關(guān)閥件周圍形成下低上高的壓差,，流體壓力推動關(guān)閉件向下移動，關(guān)閉閥門,。
    特點：流體壓力范圍上限較高，可任意安裝（需定制）但必須滿足流體壓差條件,。

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