先導(dǎo)控制閥是直動(dòng)式比例閥,。控制邊的尺寸經(jīng)過(guò)優(yōu)化,，可用作比例方向閥型號(hào) 4WRKE 的先導(dǎo)控制閥,。比例電磁鐵為帶可拆卸線圈的耐壓密閉型濕式插腳交流線圈。它們可將電流按比例轉(zhuǎn)換為機(jī)械力,。電流強(qiáng)度的增加會(huì)導(dǎo)致磁力相應(yīng)增加,。設(shè)定的磁力會(huì)在整個(gè)控制行程中保持不變。

先導(dǎo)控制閥主要由殼體,，比例電磁鐵,，控制閥芯和彈簧組成。
在非工作情況下,，兩個(gè)執(zhí)行機(jī)構(gòu)都連接到油箱,。如果兩個(gè)線圈中的一個(gè)勵(lì)磁，則磁力會(huì)將閥的控制閥向彈簧移動(dòng),。一旦超過(guò)遮蓋區(qū)域,，便會(huì)阻斷兩個(gè)執(zhí)行機(jī)構(gòu)中的一處連接,，轉(zhuǎn)而連接壓力腔。流體從 P 流向主級(jí)的控制腔,。

該閥由先導(dǎo)閥和主閥兩部分組成,。先導(dǎo)閥由先導(dǎo)閥芯、前彈簧,、銜鐵,、后彈簧、電磁線圈等組成,；主閥由主閥芯,、閥殼體、閥套,組成,。先導(dǎo)閥芯和主閥均采用錐閥式結(jié)構(gòu),，與液壓閥座采用線接觸，故密封性好,，泄漏少,，動(dòng)作迅速。先導(dǎo)閥芯與銜鐵采用T型槽連接,。主閥芯3的外表面上加工了3條均壓槽,，以避免主閥芯在運(yùn)動(dòng)過(guò)程中，承受不平衡的徑向力而產(chǎn)生的液壓卡緊現(xiàn)象,。閥殼體與閥套,，閥殼體與閥體均采用螺紋聯(lián)接。
