先导式方向控制阀
D31VW-D111VW系列先导式换向阀
概况
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**的控制油压力。
特点
- D*系列阀由派克在世界各地生产。
- 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。
- 先导阀带NG6。
- 通过直流或交流湿式电磁铁进行电气操作。
- 工作油口可达350bar载荷。
- 适用于D4和D8/9系列的补充：在P流道中装背压阀。
