派克PARKER電液方向控制閥D*1VW系列部分型號(hào)
派克PARKER電液方向控制閥D*1VW系列技術(shù)簡(jiǎn)介
D31, D41, D81, D91及D111系列是電液操控的4/3 （三位四通)或4/2(二位四通)方向控制閥，并由一NG6電磁閥進(jìn)行先導(dǎo)操控。
先導(dǎo)控制油的壓力和流量對(duì)主級(jí)閥芯的換向響應(yīng)時(shí)間有重要的影響。為確保證主閥芯換向可靠，應(yīng)選擇恰當(dāng)?shù)目刂朴驮春托褂瓦x項(xiàng)。(若閥芯機(jī)能有尸通丁的情況，則應(yīng)需采用外部控制油源或在主閥口內(nèi)置一個(gè)單向閥。對(duì)于換向過(guò)渡位置機(jī)能為負(fù)遮蓋的閥，建議亦按相同方法處理。)在任何工作狀況下均必須保證最低的控制壓力。
