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。 REXROTH电磁阀，德国力士乐电磁阀，Rexroth电磁阀电磁阀4WE6系列
