直动式比例换向阀，不带电气位置反馈，带集成电子装置（OBE）。
控制液流的方向与大小。
由带中心螺纹及可拆卸线圈的比例电磁铁驱动。
用于底板安装，油口布置符合ISO 4401。
弹簧对中的控制阀芯。
二位四通及三位四通比例换向阀为板式直动结构，由带中心螺纹、可拆卸线圈的比例电磁铁驱动，电磁铁通过集成电子装置控制。
该阀主要组成如下：
带连接面的阀体（1）
带压缩弹簧（3 和 4）的控制阀芯（2）
带中心螺纹的电磁铁（5 和 6）
集成电子装置（7）
电磁铁（5、6）断电时，压缩弹簧（3、4）使控制阀芯（2）保持中位。
通过给一个比例电磁铁通电来直接驱动控制阀芯（2），例如给电磁铁“b”（6）通电
控制阀芯（2）按电输入信号成比例地向左移动
P 至 A、B 至 T 通过具有渐进流量特性的节流截面连通
电磁铁（6）断电
控制阀芯（2）在压缩弹簧（3）的作用下返回中位
该版本功能与三阀位版本基本相同，但二阀位版本仅配电磁铁“a”。第二个比例电磁铁的位置在NG6中采用螺塞（8.1），在NG10中采用盖板（8.2）。
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。
