所以使用比例阀或伺服阀的目的就是：以电控方式实现对流量的节流控制（当然经过结构上的改动也可实现压力控制等），既然是节流控制，就必然有能量损失，伺服阀和其它阀不同的是，它的能量损失更大一些，因为它需要一定的流量来维持前置级控制油路的工作。RE25R35W4SN1XWM

伺服阀的主阀一般来说和换向阀一样是滑阀结构，只不过阀芯的换向不是靠电磁铁来推动，而是靠前置级阀输出的液压力来推动，这一点和电液换向阀比较相似，只不过电液换向阀的前置级阀是电磁换向阀，而伺服阀的前置级阀是动态特性比较好的喷嘴挡板阀或射流管阀。 R900405544 Z2FS6-2-4X/1QJV

也就是说，伺服阀的主阀是靠前置级阀的输出压力来控制的，而前置级阀的压力则来自于伺服阀的入口p，假如p口的压力不足，前置级阀就不能输出足够的压力来推动主阀芯动作。 D1VW020DNJGG5 D1VW020BNJCGJ5

而我们知道，当负载为零的时候，如果四通滑阀完全打开，p口压力＝t口压力＋阀口压力损失（忽略油路上的其它压力损失），如果阀口压力损失很小，t口压力又为零，那么p口的压力就不足以供给前置级阀来推动主阀芯，整个伺服阀就失效了。所以伺服阀的阀口做得偏小，即使在阀口全开的情况下，也要有一定的压力损失，来维持前置级阀的正常工作。
