DR 型压力阀为由二次回路控制的先导式减压阀。

减压阀主要由带主阀芯插装件（3）的主阀（1），以及带调节装置的先导阀（2）组成。

静止位置时，阀处于开启状态，液压油由 B 通道经主阀插装件（3）无阻碍地流向 A 通道。A 通道压力作用于主阀芯下侧，同时经喷嘴（4）作用于主阀芯（3）的弹簧加载侧，并经通道（5）作用于先导控制阀（2）中的钢球（6）。该压力还经喷嘴（7）、控制油路（8）、单向阀（9）和喷嘴（10）作用于钢球（6）。根据弹簧（11）的设定，钢球（6）前方、通道（5）及弹簧腔（12）内建立压力，使控制阀芯（13）保持开启。B 通道的液压油可经主阀插装件（3）无阻碍地流向 A 通道，直至 A 通道压力超过弹簧（11）的设定值并使钢球（6）开启，此时控制阀芯（13）向关闭方向移动。

A通道压力与弹簧（11）的设定压力达到平衡时，即达到所需减压值。

弹簧腔（14）的先导油始终经控制管路（15）外部回油至油箱。

可选装单向阀（16），以实现从通道 A 至通道 B 的自由回流。

压力表接口（17）可用于检查通道 A 中降低后的压力。
