特点： 在零压差或真空、高压时亦能可动作，但功率较大，要求必须安装
德国REXROTH力士乐先导式电磁阀：
 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 。

 力士乐REXROTH电磁阀里有密闭的腔，在的不同位置开有通孔，每个孔都通向不同的油管，腔中间是阀，两面是两块电磁铁，哪面的磁铁线圈通电阀体就会被吸引到哪边，通过控制阀体的移动来档住或漏出不同的排油的孔，而进油孔是常开的，液压油就会进入不同的排油管，然后通过油的压力来推动油刚的活塞，活塞又带动活塞杆，活塞竿带动机械装置动。这样通过控制电磁铁的电流就控制了机械运动。
