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

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