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。

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，控制比伺服要灵活一些。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，响应要慢。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!
