伺服阀的主阀一般来说和换向阀一样是滑阀结构，只不过阀芯的换向不是靠电磁铁来推动，而是靠前置级阀输出的液压力来推动，这一点和电液换向阀比较相似，只不过电液换向阀的前置级阀是电磁换向阀，而伺服阀的前置级阀是动态特性比较好的喷嘴挡板阀或射流管阀。
也就是说，伺服阀的主阀是靠前置级阀的输出压力来控制的，而前置级阀的压力则来自于伺服阀的入口p，假如p口的压力不足，前置级阀就不能输出足够的压力来推动主阀芯动作。

    3）先导式电磁阀：
原理：通电时，电磁力把先导孔打开，上腔室压力迅速下降，在关 闭件周围形成上低下高的压差，流体压力推动关闭件向上移动，阀门打开；断电时，弹簧力把先导孔关闭，入口压力通过旁通孔迅速腔室在关阀件周围形成下低上高的压差，流体压力推动关闭件向下移动，关闭阀门。
    特点：流体压力范围上限较高，可任意安装（需定制）但必须满足流体压差条件。

二、电磁阀从阀结构和材料上的不同与原理上的区别，分为六个分支小类：直动膜片结构、分步直动膜片结构、先导膜片结构、直动活塞结构、分步直动活塞结构、先导活塞结构。
三、电磁阀按照功能分类：水用电磁阀、蒸汽电磁阀、制冷电磁阀、低温电磁阀、燃气电磁阀、消防电磁阀、氨用电磁阀、气体电磁阀、液体电磁阀、微型电磁阀、脉冲电磁阀、液压电磁阀 常开电磁阀、油用电磁阀、直流电磁阀、高压电磁阀、防爆电磁阀等。
