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，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！

经济性：
它选用的尺度之一，但必须是在安全、适用、可靠的基础上的经济。
经济性不单是产品的售价，更要优先考虑其功能和质量以及安装维修及其它附件所需用费用。
更重要的是，一只电磁阀在整个自控系统中在整个自控系统中乃至生产线中所占成本微乎其微，如果贪图小便宜错选而造成损害群是巨大的。
4安装注意
1、安装时应注意阀体上箭头应与介质流向一致。不可装在有直接滴水或溅水的地方。电磁阀应垂直向上安装；
2、电磁阀应保证在电源电压为额定电压的15%-10%波动范围内正常工作；
3、电磁阀安装后，管道中不得有反向压差。并需通电数次，使之适温后方可正式投入使用；
4、电磁阀安装前应彻底清洗管道。通入的介质应无杂质。阀前装过滤器；
5、当电磁阀发生故障或清洗时，为保证系统继续运行，应安装旁路装置。
