的工作。
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。 SAGAM-10/350 34

一般说来，好像伺服系统都是闭环控制，比例多用于开环控制；其次比例阀类型要多，有比例压力、流量控制阀等，控制比伺服药灵活一些。从他们内部结构看，伺服阀多是零遮盖，比例阀则有一定的死区，控制精度要低，向应要慢。但从发展趋势看，特别在比例方向流量控制阀和伺服阀方面，两者性能差别逐渐在缩小，另外比例阀的成本比伺服阀要低许多，抗污染能力也强！
