电磁阀从原理上分为三大类（即：直动式、分步直动式、先导式），而从阀瓣结构和材料上的不同与原理上的区别又分为六个分支小类（直动膜片结构、分步重片结构、先导膜式结构、直动活塞结构、分步直动活塞结构、先导活塞结构）。

直动式电磁阀：

原理：通电时，电磁线圈产生电磁力把关闭件从阀座上提起，阀门打开；断电时，电磁力消失，弹簧把关闭件压在阀座上，阀门关闭。

特点：在真空、负压、零压时能正常工作，但通径一般不超过25mm。

分布直动式电磁阀：

原理：它是一种直动和先导式相结合的原理，当入口与出口没有压差时，通电后，电磁力直接把先导小阀和主阀关闭件依次向上提起，阀门打开。当入口与出口达到启动压差时，通电后，电磁力先导小阀，主阀下腔压力上升，上腔压力下降，从而利用压差把主阀向上推开；断电时，先导阀利用弹簧力或介质压力推动关闭件，向下移动，使阀门关闭。

特点：在零压差或真空、高压时亦能可*动作，但功率较大，要求必须水平安装。

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。

电动阀与电磁阀的区别

电磁阀是电磁线圈通电后产生磁力吸引克服弹簧的压力带动阀芯动作，就一电磁线圈，结构简单，价格便宜，只能实现开关；

电动阀是通过电动机驱动阀杆，带动阀芯动作，电动阀又分（关断阀）和调节阀。关断阀是两位式的工作即全开和全关，调节阀是在上面安装电动阀门定位器，通过闭环调节来使阀门动态的稳定在一个位置上。
