FESTO電磁閥是利用電滋因素保持管控主要目的的工業企業產品，用在化工調控平臺中改變媒介的領域、總流量、快慢和相關的參數設置。電磁能感應爐閥重要由繼電氣實施有效把控。然而，電磁能感應爐閥就可以協調一致有差異 的電線來維持 期望的有效把控，而有效把控的要求和輕松性都也能獲得維持。電磁能感應爐閥有較多種，*經常用的是單方面閥、**閥、放向的控制閥、進程轉換閥等。電磁能閥可以依照帶動力機又有汽動電磁振動器閥、自動磁感應閥和液壓機電磁振動器閥。 　渦流閥會選擇*先大概順次尊循**性，正規性，常用性，劃算性這幾種理論依據，前者是會選擇六大地方的實地工程即排水管道叁數、射流叁數、負壓叁數、電叁數、運作行為、比較特殊條件進行會選擇。

   

FESTO電磁閥的(de)(de)用(yong)途(tu)電(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)(fa)(fa)用(yong)于(yu)液(ye)體(ti)和(he)氣(qi)體(ti)管路的(de)(de)開(kai)(kai)(kai)關(guan)控(kong)(kong)制(zhi)(zhi)，是兩位DO控(kong)(kong)制(zhi)(zhi)。一般用(yong)于(yu)小(xiao)型管道(dao)(dao)的(de)(de)控(kong)(kong)制(zhi)(zhi)。電(dian)(dian)(dian)(dian)(dian)動閥(fa)(fa)(fa)(fa)用(yong)于(yu)液(ye)體(ti)、氣(qi)體(ti)和(he)風(feng)系(xi)(xi)(xi)統(tong)(tong)管道(dao)(dao)介質流(liu)量(liang)的(de)(de)模擬(ni)量(liang)調節，是AI控(kong)(kong)制(zhi)(zhi)。在大(da)型閥(fa)(fa)(fa)(fa)門和(he)風(feng)系(xi)(xi)(xi)統(tong)(tong)的(de)(de)控(kong)(kong)制(zhi)(zhi)中也(ye)可(ke)以(yi)用(yong)電(dian)(dian)(dian)(dian)(dian)動閥(fa)(fa)(fa)(fa)做兩位開(kai)(kai)(kai)關(guan)控(kong)(kong)制(zhi)(zhi)。電(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)(fa)(fa)只能用(yong)作(zuo)(zuo)開(kai)(kai)(kai)關(guan)量(liang)，是DO控(kong)(kong)制(zhi)(zhi)，只能用(yong)于(yu)小(xiao)管道(dao)(dao)控(kong)(kong)制(zhi)(zhi)，常見于(yu)DN50及以(yi)下(xia)管道(dao)(dao)，往上就(jiu)很(hen)少了。電(dian)(dian)(dian)(dian)(dian)動閥(fa)(fa)(fa)(fa)可(ke)以(yi)有AI反(fan)饋信號，可(ke)以(yi)由(you)DO或(huo)(huo)AO控(kong)(kong)制(zhi)(zhi)，比較見于(yu)大(da)管道(dao)(dao)和(he)風(feng)閥(fa)(fa)(fa)(fa)等。1.開(kai)(kai)(kai)關(guan)形式(shi)電(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)(fa)(fa)通(tong)過線(xian)圈驅(qu)動，只能開(kai)(kai)(kai)或(huo)(huo)關(guan)，開(kai)(kai)(kai)關(guan)時(shi)動作(zuo)(zuo)時(shi)間(jian)短。電(dian)(dian)(dian)(dian)(dian)動閥(fa)(fa)(fa)(fa)的(de)(de)驅(qu)動一般是用(yong)電(dian)(dian)(dian)(dian)(dian)機，開(kai)(kai)(kai)或(huo)(huo)關(guan)動作(zuo)(zuo)完成需要一定的(de)(de)時(shi)間(jian)模擬(ni)量(liang)的(de)(de)，可(ke)以(yi)做調節。2.工作(zuo)(zuo)性質電(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)(fa)(fa)一般流(liu)通(tong)系(xi)(xi)(xi)數很(hen)小(xiao)，而且工作(zuo)(zuo)壓力差(cha)很(hen)小(xiao)。比如一般25口(kou)徑的(de)(de)電(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)(fa)(fa)流(liu)通(tong)系(xi)(xi)(xi)數比15口(kou)徑的(de)(de)電(dian)(dian)(dian)(dian)(dian)動球閥(fa)(fa)(fa)(fa)小(xiao)很(hen)多。

德國FESTO費斯托電磁閥是由電磁線圈和磁芯組成，是包含一個或幾個孔的閥體。當線圈通電或斷電時，磁芯的運轉將導致流體通過閥體或被切斷，以達到改變流體方向的目的。電磁閥的電磁部件由固定鐵芯、動鐵芯、線圈等部件組成；閥體部分由滑閥芯、滑閥套、彈簧底座等組成。電磁線圈被直接安裝在閥體上，閥體被封閉在密封管中，構成一個簡潔、緊湊的組合。我們在生產中常用的電磁閥有二位三通、二位四通、二位五通等。這里先說說二位的含義：對于電磁閥來說就是帶電和失電，對于所控制的閥門來說就是開和關。
