三通减压阀类型 3 DREP 6.. 由比例线圈直接操作。它用于将电气输入信号转化为比例压力输出信号。比例线圈是带湿式柱销的可控直流线圈，带对中螺纹和可拆卸线圈。这些线圈可选择性地由外部控制电子元件（类型 3DREP）或内部控制电子元件（类型 3DREPE）进行驱动。

设置：

阀基本构成包括：

– 带安装面的阀体（1）

– 控制阀芯（2），带压力测量阀芯（3，4）

– 带对中螺纹的线圈（5，6）

– 可选集成控制电子元件（7）

功能：

通过比例线圈设置 A 或 B 中的压力。具体压力取决于电流。线圈（5，6）断电后，控制阀芯（2）将通过压缩弹簧（8）保持在中心位置。油口 A 和 B 连接到 T，以便液压油可以不受阻挡地流入油箱。通过为比例线圈（例如线圈 "a"（5））通电，压力测量阀芯 （3）和控制阀芯（2）将向右移动。这样将通过具有渐进流量特性的节流截面，打开从 P 到 B 及从 A 到 T 的连接。在通道 B 中形成的压力以压力测量阀芯（4）的表面作用于控制阀芯，并与磁力相反。压力测量阀芯（4）受线圈 "b" 支撑。如果压力超过线圈 "a" 上设置的值，将逆磁力方向回推控制阀芯 （2），并建立 B 与 T 的连接，直到重新获得设置的压力。压力与线圈电流成比例。在关闭线圈后，控制阀芯（2）将通过压缩弹簧（8）返回中心位置。通过可选的手动操控（9，10），可使控制阀芯（2）在无线圈通电的情况下发生位移。
