Parker派克D41FH系列先導(dǎo)式比例換向閥

此系列先導(dǎo)式比例換向閥被用于控制流量,。該閥具有集成的電子元件,，主級的閥芯位置可調(diào)。典型的應(yīng)用是：流量控制和可實現(xiàn)流量調(diào)節(jié),，在快速/低速特性下的工作運行帶有閥芯位置監(jiān)控用于：壓力機控制，動態(tài)位置調(diào)節(jié)和壓力/流量閉環(huán)系統(tǒng)。技術(shù)特性：泄漏量小,，高頻響，通油能力大，準(zhǔn)確的故障狀態(tài)診斷,，零遮蓋閥的機械式零點調(diào)節(jié),，高強度，閥芯位置的位移反饋,，可選擇閥芯位置行程監(jiān)控
