    力士樂(lè)電磁閥閥體全不銹鋼；對(duì)于強(qiáng)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(dòng)作不頻繁的場(chǎng)合。氨用閥則不能采用銅材。

    力士樂(lè)電磁閥爆炸性環(huán)境：必須選用相應(yīng)防爆等級(jí)產(chǎn)品，露天安裝或粉塵多場(chǎng)合應(yīng)選用防水，防塵品種。

    REXROTH電磁閥公稱(chēng)壓力應(yīng)超過(guò)管內(nèi)zui高工作壓力。

    力士樂(lè)電磁閥里有密閉的腔，在不同位置開(kāi)有通孔，每個(gè)孔連接不同的油管，腔中間是活塞，兩面是兩塊電磁鐵，哪面的磁鐵線圈通電閥體就會(huì)被吸引到哪邊，通過(guò)控制閥體的移動(dòng)來(lái)開(kāi)啟或關(guān)閉不同的排油孔，而進(jìn)油孔是常開(kāi)的，液壓油就會(huì)進(jìn)入不同的排油管，然后通過(guò)油的壓力來(lái)推動(dòng)油缸的活塞，活塞又帶動(dòng)活塞桿，活塞桿帶動(dòng)機(jī)械裝置。這樣通過(guò)控制電磁鐵的電流通斷就控制了機(jī)械運(yùn)動(dòng)。

    REXROTH電磁閥產(chǎn)品廣泛應(yīng)用于壓路機(jī)、混泥土攪拌車(chē)、機(jī)床、汽車(chē)、紡織工業(yè)、輕工業(yè)、鋼廠、采礦業(yè)、油田、石化、風(fēng)能、通用自動(dòng)化、水利工程、海事工程、冶金、塑料機(jī)械、通用機(jī)械、壓機(jī)、鉆孔機(jī)、叉車(chē)、推土機(jī)、起重機(jī)、裝載機(jī)、混泥土泵、挖掘機(jī)、印刷與紙張?zhí)幚?、食品包裝、木工機(jī)械、橡膠、電子和半導(dǎo)體行。

    力士樂(lè)電磁閥是用電磁控制的工業(yè)設(shè)備，是用來(lái)控制流體的自動(dòng)化基礎(chǔ)元件，屬于執(zhí)行器，并不限于液壓、氣動(dòng)。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(lè)電磁閥可以配合不同的電路來(lái)實(shí)現(xiàn)預(yù)期的控制，而控制的精度和靈活性都能夠保證。
