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。
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。

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。
伺服阀其实缺点极多：能耗浪费大

、容易出故障、抗污染能力差、价格昂贵等等等等，好处只有一个：动态性能是所有液压阀中最高的。就凭着这一个优点，在很多对动态特性要求高的场合不得不使用伺服阀，如飞机火箭的舵机控制、汽轮机调速等等。动态要求低一点的，基本上都是比例阀的天下了。
一般说来，好像伺服系统都是闭环控制，
