美國(guó)ASCO電磁閥資料下載52100001：直動(dòng)式電磁閥原理：通電時(shí)，電磁線圈產(chǎn)生電磁力把關(guān)閉件從閥座上提起，閥門打開；斷電時(shí)，電磁力消失，彈簧把關(guān)閉件壓在閥座上，關(guān)閉。

美國(guó)ASCO電磁閥資料下載52100001：分布直動(dòng)式原理： 他是一種直動(dòng)式和先導(dǎo)式相結(jié)合的原理。常閉式--當(dāng)入口與出口沒有壓差時(shí)，通電后電磁力直接打開先導(dǎo)孔連接主閥活塞依次向上提起，閥門打開；當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí)，通電后，電磁力先打開先導(dǎo)孔，主閥活塞上腔壓力下降，從而利用壓差和電磁力拉動(dòng)主活塞，閥口打開；斷電時(shí)，靠彈簧復(fù)位關(guān)閉先導(dǎo)孔，主活塞上腔增壓，推動(dòng)主活塞向下移動(dòng)，閥關(guān)閉。常開式與常閉式相反。
