液控伺服閥主要是指電液伺服閥,它在接受電氣模擬信號后，相應(yīng)輸出調(diào)制的流量和壓力。它既是電液轉(zhuǎn)換元件，也是功率放大元件，它能夠?qū)⑿」β实奈⑷蹼姎廨斎胄盘栟D(zhuǎn)換為大功率的液壓能（流量和壓力）輸出。在電液伺服系統(tǒng)中，它將電氣部分與液壓部分連接起來，實現(xiàn)電液信號的轉(zhuǎn)換與液壓放大。電液伺服閥是電液伺服系統(tǒng)控制的核心。
液控伺服閥是在伺服系統(tǒng)中將電信號輸入轉(zhuǎn)換為功率較大的壓力或流量壓力信號輸出的執(zhí)行元件。它是一種電液轉(zhuǎn)換和功率放大元件。伺服閥的靈敏度高，快速性好，能將很小的電信號（例如10毫安）轉(zhuǎn)換成很大的液壓功率（如幾十匹馬力以上），可以驅(qū)動多種類型的負(fù)載。過去人們曾把噴嘴檔板閥、射流管或滑閥伺服馬達(dá)等液壓放大裝置都列入伺服閥范圍內(nèi)。20世紀(jì)70年代以來，伺服閥一般僅指電液伺服閥。

伺服閥的主閥一般來說和換向閥一樣是滑閥結(jié)構(gòu)，只不過閥芯的換向不是靠電磁鐵來推動，而是靠前置級閥輸出的液壓力來推動，這一點和電液換向閥比較相似，只不過電液換向閥的前置級閥是電磁換向閥，而伺服閥的前置級閥是動態(tài)特性比較好的噴嘴擋板閥或射流管閥。
也就是說，伺服閥的主閥是靠前置級閥的輸出壓力來控制的，而前置級閥的壓力則來自于伺服閥的入口p，假如p口的壓力不足，前置級閥就不能輸出足夠的壓力來推動主閥芯動作。
而我們知道，當(dāng)負(fù)載為零的時候，如果四通滑閥完全打開，p口壓力=t口壓力+閥口壓力損失（忽略油路上的其它壓力損失），如果閥口壓力損失很小，t口壓力又為零，那么p口的壓力就不足以供給前置級閥來推動主閥芯，整個伺服閥就失效了。所以伺服閥的閥口做得偏小，即使在閥口全開的情況下，也要有一定的壓力損失，來維持前置級閥的正常工作。
