　　所以使用比例閥或伺服閥的目的就是：以電控方式實現對流量的節(jié)流控制（當然經過結構上的改動也可實現壓力控制等），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構，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。
