先導(dǎo)控制閥是直動式比例閥?？刂七叺某叽缃?jīng)過優(yōu)化，可用作比例方向閥型號 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)換為機械力。電流強度的增加會導(dǎo)致磁力相應(yīng)增加。設(shè)定的磁力會在整個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，兩個執(zhí)行機構(gòu)都連接到油箱。如果兩個線圈中的一個勵磁，則磁力會將閥的控制閥向彈簧移動。一旦超過遮蓋區(qū)域，便會阻斷兩個執(zhí)行機構(gòu)中的一處連接，轉(zhuǎn)而連接壓力腔。流體從 P 流向主級的控制腔。

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，以避免主閥芯在運動過程中，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。
