二位三通電磁閥為雙線圈控制，一個線圈瞬間通電后關閉電源、閥打開，另一個線圈瞬間通電后關閉電源、閥關閉。可以長時間保持關閉或打開狀態，能使線圈壽命更長。在高溫管道中使用佳。
一進二出：當電磁閥線圈通電時，出介質端路打開，第二路關閉；當電磁閥線圈斷電時，出介質端路關閉，第二路打開；
二進一出：當電磁閥線圈通電時，進介質端路打開，第二路關閉；當電磁閥線圈斷電時，進介質端路關閉，第二路打開；(此內閥兩進口端前必需加單向閥)

   氣動電磁閥通過控制閥體的移動來檔住或漏出不同的排油的孔，而進油孔是常開的，液壓油就會進入不同的排油管，然后通過氣動電磁閥的油的壓力來推動油剛的活塞，這樣通過控制氣動電磁閥的電磁鐵的電流就控制了整個電磁閥的機械運動。
電(dian)磁(ci)閥(fa)(fa)是用來控制流體的自動化基礎元件，屬于執(zhi)行器；并不限于液(ye)(ye)壓(ya)(ya)(ya)，氣動。電(dian)磁(ci)閥(fa)(fa)用于控制液(ye)(ye)壓(ya)(ya)(ya)流動方向，工廠的機械裝置(zhi)一般都由液(ye)(ye)壓(ya)(ya)(ya)鋼控制，所以就會用到電(dian)磁(ci)閥(fa)(fa)。

氣動電磁閥：
在真空、負壓、零壓時能正常工作，但通徑一般不超過25毫米。
在零壓差或真空、高壓時亦能可動作，但功率較大，要求必須水平安裝。
流(liu)體壓力范(fan)圍上限(xian)較(jiao)高(gao)，可任意安裝(zhuang)(需定制)但必須滿足流(liu)體壓差條件。

 由于氣動技術越來越多地應用于各行業的自動裝配和自動加工小件、特殊物品的設備上，原有傳統的氣動元件性能正在不斷提高，同時陸續開發出適應市場要求的新產品，使氣動元件的品種日益增加，其發展趨勢主要有以下幾個方面：
體(ti)積(ji)(ji)更小(xiao)，重量更輕(qing)，功耗(hao)更低.在電子元件(jian)(jian)(jian)、藥品等制造(zao)行業(ye)中，由于(yu)被加(jia)工件(jian)(jian)(jian)體(ti)積(ji)(ji)很(hen)小(xiao)，勢必限制了(le)氣動元件(jian)(jian)(jian)的(de)尺(chi)(chi)寸，小(xiao)型(xing)化、輕(qing)型(xing)化是氣動元件(jian)(jian)(jian)的(de)個發(fa)(fa)展方向。國外已開發(fa)(fa)了(le)僅大(da)拇指大(da)小(xiao)、有效(xiao)截面積(ji)(ji)為(wei)0.2mm2的(de)超小(xiao)型(xing)電磁閥(fa)。能開發(fa)(fa)出外形(xing)尺(chi)(chi)寸小(xiao)而(er)流量較大(da)的(de)元件(jian)(jian)(jian)更為(wei)理想。為(wei)此(ci)，相同(tong)外形(xing)尺(chi)(chi)寸的(de)閥(fa)，流量已提高(gao)2~3.3倍。有一(yi)種系(xi)列的(de)小(xiao)型(xing)電磁閥(fa)，其閥(fa)體(ti)寬僅10mm，有效(xiao)面積(ji)(ji)可達
