rexroth叠加式双单向节流阀设计安装的位置不妥，会出现减压阀阀后压力忽高忽低，管网压力严重偏离允许范围，伴随毁坏淋浴器，水管爆裂和损坏用户水表等事故发生；有时也会水流不畅，分区内出现无规律的断水现象，影响用户用水。

Rexroth力士乐叠加式双单向节流阀主阀膜片有裂痕和O型圈损坏，及导阀连通管堵塞，造成减压阀减压作用削弱或者失效。这对分区管网危害极大，特别是许多用水设备可能因超压力而出现爆管，必须及时修复。比例式(活塞型)减压阀阀体上的透吸气小孔如出现滴漏不止，表明阀芯上几档O型密封圈已经磨损，要更换密封件。但在修理拆装减压元件时，要谨慎细心，调换内密封件；清理杂物时，应因势利导，不要用金属棒、硬梗撬阀  减压阀的活动部位，使用木榔头和木柄敲击震动，慢慢拆卸阀内部件。
