一種是開(kāi)關(guān)控制：要么全開(kāi)、要么全關(guān)，流量要么、要么小，沒(méi)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(kāi)任意一個(gè)開(kāi)度，由此控制通過(guò)流量的大小，這類閥有手動(dòng)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(shí)現(xiàn)對(duì)流量的節(jié)流控制（當(dāng)然經(jīng)過(guò)結(jié)構(gòu)上的改動(dòng)也可實(shí)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?yàn)樗枰欢ǖ牧髁縼?lái)維持前置級(jí)控制油路的工作。

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。
