力士乐电磁阀弹簧过硬，反作用力过大，线圈匝数太少，吸力不够也可使得线圈烧毁。紧急处理时，可将线圈上的手动按钮正常工作时的位打到位，使得阀打开。

    力士乐电磁阀卡住。电磁阀的滑阀套与阀芯的配合间隙很小（小于0.008mm），一般都是单件装配，当有机械杂质带入或润滑油太少时，很容易卡住。处理方法可用钢丝从头部小孔捅入，使其弹回。

    根本的解决方法是要将REXROTH电磁阀拆下，取出阀芯及阀芯套，用CCI4清洗，使得阀芯在阀套内动作灵活。

    REXROTH电磁阀接线头松动或线头脱落，电磁阀不得电，可紧固线头。

    力士乐电磁阀线圈烧坏，可拆下电磁阀的接线，用万用表测量，如果开路，则电磁阀线圈烧坏。原因有线圈受潮，引起绝缘不好而漏磁，造成线圈内电流过大而烧毁，因此要防止雨水进入电磁阀。

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