先导控制阀是直动式比例阀，其控制边几何形状针对4WRKE比例换向阀的先导控制用途进行了优化。比例电磁铁为耐压密封的湿式直流电磁铁，线圈可拆卸，可将电流按比例转换为机械力。电流增加时，电磁力相应增大；设定的电磁力在整个控制行程中保持恒定。
先导阀主要由阀体（1）、比例电磁铁（2、3）、控制阀芯（4）及弹簧（5、6）组成。未动作时两个执行端均与油箱相连。激励其中一个电磁铁（2或3）后，电磁力使阀芯（4）朝弹簧（5或6）移动。越过遮盖区后，封闭其中一个执行端至油箱的连接，同时接通压力腔，使油液由P流向主级控制腔。
4WRKE型阀为两级比例换向阀，控制流向及流量。主级采用位置闭环控制，因此即使流量较大，阀芯位置也不受液动力影响。
该阀主要由先导阀（1）、阀体（8）、主阀芯（7）、盖板（5、6）、对中弹簧（4）、感应式位置传感器（9）及减压阀（3）组成。无输入信号时，对中弹簧（4）使主阀芯保持中位，盖板内两个控制腔经先导阀芯（2）与油箱相通。主阀芯通过位置传感器连接至匹配的控制电子装置。主阀芯位置变化与放大器加法节点处指令值变化均会产生电压差。电子装置比较指令值与实际值，确定控制偏差，向先导阀（1）的比例电磁铁供电。电流产生电磁力，经推杆驱动阀芯，通过控制截面的液流调节主阀芯。主阀芯（7）及其连接的位置传感器铁芯移动，直至实际值与指令值相符。稳定控制时，主阀芯受力平衡并保持相应位置。阀芯行程与开口随指令值成比例变化。控制电子装置集成于阀内，阀与电子装置配套调整，使批量产品偏差较小。
不得使回油管路排空；相应安装条件下必须安装预紧阀，预紧压力约2 bar。
第二级基本由本公司比例阀模块组成。“主级零点”已在工厂调整，可通过控制电子装置中的电位器，在额定行程的±30%范围内调整。拆下盖壳前侧的螺塞即可接近集成控制电子装置。更换先导阀或控制电子装置后，必须重新调整。所有调整只能由经过指导的专业人员进行。
零点的改变可能损坏系统，只能由经过指导的专业人员实施！
