力士樂四通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電磁閥公稱壓力應(yīng)超過管內(nèi)zui高工作壓力。
Rexroth四通電磁閥在我們的生產(chǎn)中應(yīng)用也很多，其工作原理如下：當(dāng)有電流通過線圈時(shí)，產(chǎn)生勵(lì)磁作用，固定鐵芯吸合動(dòng)鐵芯，動(dòng)鐵芯帶動(dòng)滑閥芯并壓縮彈簧，改變了滑閥芯的位置，從而改變了流體的方向。 力士樂電磁閥依靠彈簧的彈力推動(dòng)滑閥芯，頂回動(dòng)鐵芯，使流體按原來的方向流動(dòng)。在我們制氧生產(chǎn)中，分子篩切換系統(tǒng)強(qiáng)制閥的開關(guān)就是通過二位四通電磁閥來控制的，氣流分別供至強(qiáng)制閥的活塞兩端。從而來控制強(qiáng)制閥的啟閉。 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 R900939012 4WE6Y6X/EG24N9K4SO9
