滑动阀芯式的先导式换向阀用于控制油流的方向。主滑动
阀芯通过控制油的压力换到所要求的位置上并通过止挡机
构、定位机构或弹簧保持在其位置上。
控制油的压力和流量对主滑动阀芯的换向性能有重要的影
响。为了保证换向可靠，使用时必须选择相应的控制油
流。
在任何工作状况下必须保证阀的最低的控制油压力。

特点
1. D系列阀由派克在世界各地生产。
2. 3位4通和2位4通滑动阀芯式换向阀可用于阀块式或
板式安装。
3. 先导阀带NG6。
4. 通过直流或交流湿式电磁铁进行电气操纵。
5. 工作油口可达 350ban载荷。
6. 适用于D4和D8/9系列的补充：
在P流道中装背压阀。

阀的安装表面必须满足下列要求：
平面度:最大允许0.01mm/10mm
粗糙度:最大允许R最大6.3um
