ZDC型阀是二通或三通结构的直动式供油压力补偿器。
它们在P通道中作为供油压力补偿器，用于负载补偿。
该阀主要由阀体（1）、控制阀芯（2）、带弹簧座（4）的压缩弹簧（3），以及装有梭阀（6）的盖板（5）组成。
当压差P1→A1或P1→B1小于10 bar时，压缩弹簧（3）使控制阀芯（2）保持在P2至P1的开启位置。
若压差超过 10 bar，控制阀芯（2）将向左移动，直至恢复规定压差。
与进油压力补偿器配合使用时，先导式比例换向阀必须采用“外部先导供油”！
外部先导供油时，与P通道的连接封闭，先导油取自独立控制回路。
内部先导供油时，与P通道的连接开启，先导油取自压力补偿器节流侧上游，底板中的X口封闭。
