德国力士乐先导式溢流阀DBE6X型的特点：可通过线圈电流进行调节；技术参数和所选的电子控制单元；电磁铁类型Imax=0.8A或者Imax=2.5A；即使当电子控制单元损坏时，也能zui大程度地实现过压保护（线圈电流I＞Imax）用于阀板安装，安装孔符合ISO4401-03-02-0-94；符合DIN43650-AM2标准的线缆插座，包括在供货范围内；具有斜坡功能和阀调节功能的外部电子控制单元。 

力士乐Rexroth先导式比例溢流阀的的工作原理：通过电子控制单元确定某个设定值，对系统压力进行调节。电子控制单元根据设定值，利用稳压PWM电流（PWM=脉冲宽度调制）对线圈进行控制。利用震荡信号对稳压电流进行调制，以保证获得极小的滞后量。比例电磁铁将电流转变成机械作用力，并通过衔铁挺杆作用于先导级中的主弹簧上。通过个供油孔将流量为＜0.6L/min的控制油供应给先导级。通过锥孔/座孔构造确定压力级“Pmax”
