一種是開關(guān)控制：要么全開、要么全關(guān)，流量要么、要么最小，沒有中間狀態(tài)，如普通的電磁直通閥、電磁換向閥、電液換向閥。

另一種是連續(xù)控制：閥口可以根據(jù)需要打開任意一個開度，由此控制通過流量的大小，這類閥有手動控制的，如節(jié)流閥，也有電控的，如比例閥、伺服閥。

所以使用比例閥或伺服閥的目的就是：以電控方式實現(xiàn)對流量的節(jié)流控制（當(dāng)然經(jīng)過結(jié)構(gòu)上的改動也可實現(xiàn)壓力控制等），既然是節(jié)流控制，就必然有能量損失，伺服閥和其它閥不同的是，它的能量損失更大一些，因為它需要一定的流量來維持前置級控制油路的工作。

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。
