伺服閥的主閥一般來(lái)說(shuō)和換向閥一樣是滑閥結(jié)構(gòu)，只不過(guò)閥芯的換向不是靠電磁鐵來(lái)推動(dòng)，而是靠前置級(jí)閥輸出的液壓力來(lái)推動(dòng)，這一點(diǎn)和電液換向閥比較相似，只不過(guò)電液換向閥的前置級(jí)閥是電磁換向閥，而伺服閥的前置級(jí)閥是動(dòng)態(tài)特性比較好的噴嘴擋板閥或射流管閥。

也就是說(shuō)，伺服閥的主閥是靠前置級(jí)閥的輸出壓力來(lái)控制的，而前置級(jí)閥的壓力則來(lái)自于伺服閥的入口p，假如p口的壓力不足，前置級(jí)閥就不能輸出足夠的壓力來(lái)推動(dòng)主閥芯動(dòng)作。

而我們知道，當(dāng)負(fù)載為零的時(shí)候，如果四通滑閥完全打開(kāi)，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(jí)閥來(lái)推動(dòng)主閥芯，整個(gè)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(kāi)的情況下，也要有一定的壓力損失，來(lái)維持前置級(jí)閥的正常工作。
