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！

定流量阀和横流量调节阀都是变阻力设备，它们是以流体的差压作为动力，并根据系统工况（差压）变化，自动改变阻力系数，保持流量阀和横流量的恒定，通过恒定各个支路的流量来实现整个系统流量的均衡输配，消除冷热不均的现象。在总流量足够的条件下，各个支路的流量变化不会互相影响，系统比较稳定。
定流量阀和恒流量调节阀不同的是：
