美國(guó)派克電磁閥是一種不需要壓力啟動(dòng)（零壓?jiǎn)?dòng)）的電磁閥，常適用于小口徑、低壓力或真空情況下的管道中，并且響應(yīng)速度非?？?，動(dòng)作時(shí)間很短，對(duì)于啟閉頻率比較高或要求快速關(guān)斷的場(chǎng)合，都特別適合選用直動(dòng)式電磁閥。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，閥門關(guān)閉。

　　它是一種直動(dòng)和先導(dǎo)式相結(jié)合的原理，當(dāng)入口與出口沒有壓差時(shí)，通電后，電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次向上提起，閥門打開。當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí)，通電后，電磁力先導(dǎo)小閥，主閥下腔壓力上升，上腔壓力下降，從而利用壓差把主閥向上推開;斷電時(shí)，先導(dǎo)閥利用彈簧力或介質(zhì)壓力推動(dòng)關(guān)閉件，向下移動(dòng)，使閥門關(guān)閉。

　　美國(guó)派克電磁閥特點(diǎn)：

　　采用直動(dòng)式原理，膜片結(jié)構(gòu)，具有結(jié)構(gòu)簡(jiǎn)單，零件少，反應(yīng)迅速，動(dòng)作靈敏等特點(diǎn)，可任意方式安裝，但功耗比先導(dǎo)式電磁閥大，一般在5-20w，高頻通電容易燒毀線圈，但是控制簡(jiǎn)單，使用范圍廣。

　　在真空、負(fù)壓、零壓時(shí)能正常工作，通徑一般不超過25mm。

　　2.在零壓差或真空、高壓時(shí)亦可動(dòng)作，但功率較大，要求必須水平安裝。

　　工作原理

　　1）常閉型，通電時(shí)電磁線圈產(chǎn)生足夠的電磁力把運(yùn)動(dòng)部件（由磁芯、閥桿、上下部的膜片/密封件構(gòu)成）從閥座上提起，閥門開啟;斷電時(shí)彈簧力把運(yùn)動(dòng)部件壓在閥座上，閥門關(guān)閉。

　　2）常開型，動(dòng)作方向與常閉型相反。
