力士乐电磁阀在不同位置开有通孔，每个孔连接不同的油管，腔中间是活塞，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开启或关闭不同的排油孔，而进油孔是常开的。

    德国力士乐电磁阀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缸的活塞，活塞又带动活塞杆，活塞杆带动机械装置。这样通过控制电磁铁的电流通断就控制了机械运动。

    力士乐电磁阀阀体全不锈钢；对于强腐蚀的介质必须选用隔离膜片式。中性介质，也宜选用铜合金为阀壳材料的电磁阀，否则，阀壳中常有锈屑脱落，尤其是动作不频繁的场合。氨用阀则不能采用铜材。

    力士乐电磁阀爆炸性环境：必须选用相应防爆等级产品，露天安装或粉尘多场合应选用防水，防尘品种。

    REXROTH电磁阀公称压力应超过管内zui高工作压力。

上海维特锐在德国与REXROTH合作，可长期稳定供应力士乐电磁阀，REXROTH导轨，力士乐柱塞泵等产品
