伺服閥的主閥一般來說和換向閥一樣是滑閥結構，只不過閥芯的換向不是靠電磁鐵來推動，而是靠前置級閥輸出的液壓力來推動，這一點和電液換向閥比較相似，只不過電液換向閥的前置級閥是電磁換向閥，而伺服閥的前置級閥是動態(tài)特性比較好的噴嘴擋板閥或射流管閥。
也就是說，伺服閥的主閥是靠前置級閥的輸出壓力來控制的，而前置級閥的壓力則來自于伺服閥的入口p，假如p口的壓力不足，前置級閥就不能輸出足夠的壓力來推動主閥芯動作。

3）先導式電磁閥：
原理：通電時，電磁力把先導孔打開，上腔室壓力迅速下降，在關 閉件周圍形成上低下高的壓差，流體壓力推動關閉件向上移動，閥門打開；斷電時，彈簧力把先導孔關閉，入口壓力通過旁通孔迅速腔室在關閥件周圍形成下低上高的壓差，流體壓力推動關閉件向下移動，關閉閥門。
特點：流體壓力范圍上限較高，可任意安裝（需定制）但必須滿足流體壓差條件。
二、電磁閥從閥結構和材料上的不同與原理上的區(qū)別，分為六個分支小類：直動膜片結構、分步直動膜片結構、先導膜片結構、直動活塞結構、分步直動活塞結構、先導活塞結構。
三、電磁閥按照功能分類：水用電磁閥、蒸汽電磁閥、制冷電磁閥、低溫電磁閥、燃氣電磁閥、消防電磁閥、氨用電磁閥、氣體電磁閥、液體電磁閥、微型電磁閥、脈沖電磁閥、液壓電磁閥 常開電磁閥、油用電磁閥、直流電磁閥、高壓電磁閥、防爆電磁閥等。
