D31VW-D111VW系列先導(dǎo)式換向閥
概況
滑動(dòng)閥芯式的先導(dǎo)式換向閥用于控制油流的方向。主滑動(dòng)閥芯通過(guò)控制油的壓力換到所要求的位置上并通過(guò)止擋機(jī)構(gòu)、定位機(jī)構(gòu)或彈簧保持在其位置上。
控制油的壓力和流量對(duì)主滑動(dòng)閥芯的換向性能有重要的影響。為了保證換向可靠，使用時(shí)必須選擇相應(yīng)的控制油流。
在任何工作狀況下必須保證閥的zui低的控制油壓力。
特點(diǎn)
- D*系列閥由派克在世界各地生產(chǎn)。
- 3位4通和2位4通滑動(dòng)閥芯式換向閥可用于閥塊式或板式安裝。
- 先導(dǎo)閥帶NG6。
- 通過(guò)直流或交流濕式電磁鐵進(jìn)行電氣操作。
- 工作油口可達(dá)350bar載荷。
- 適用于D4和D8/9系列的補(bǔ)充：在P流道中裝背壓閥。
