二位四通和三位四通比例方向阀设计为底板安装的直动式组件。它们通过带对中螺纹和可拆卸线圈的比例线圈进行驱动。这些线圈由外部控制电子元件（类型 4WRA）或集成的控制电子元件（类型 4WRAE）进行控制。
设计：阀通常由以下部分组成：
– 带安装面的阀体（1）
– 控制阀芯（2），带有压缩弹簧（3 和 4）
– 线圈（5 和 6），带对中螺纹
– 可选集成电子元件（7）
功能：
– 当线圈（5 和 6）断电以后，控制阀芯（2）被压缩弹簧（3和 4）保持在中心位置
– 通过给比例线圈通电直接起动控制阀芯（2）例如，给线圈"b"（6）通电
– 控制阀芯（2）与电气输入信号成比例地向左移动
– 通过具有渐进流特性的类节流孔剖面，P 与 A 相连，B 与 T 相连
– 线圈（6）断电
– 控制阀芯（2）通过压缩弹簧（3）的作用返回中心位置
有 2 个阀芯位置的阀：（类型 4WRA…A…）大体上，此类阀门的功能与带 3 个阀芯位置的阀门功能相对应。但是，带 2 个阀芯位置的阀门仅配有线圈 "a"。其中 公称规格尺寸 6 配备一个插头（8.1），公称规格尺寸 10 配备一个盖（8.2）来代替第二个比例线圈。类型 4WRA 6…-2X/… 的注意事项：要防止油箱管路发生排放。在适当的安装条件下，应安装一个背压阀（背压约为 2 bar）。
4WRA重量 kg 6通经 2.0 ，10通经 6.6
4WRAE重量 kg 6通经 2.2 ，10通经 6.8
