减压阀按结构形式可分为薄膜式、弹簧薄膜式、活塞式、杠杆式和波纹管式；按阀座数目可人为单座式和双座式；按阀瓣的位置不同可分为正作用式和反作用式。先导式减压阀当减压阀的输出压力较高或通径较大时，用调压弹簧直接调压，则弹簧刚度必然过大，流量变化时，输出压力波动较大，阀的结构尺寸也将增大。为了克服这些缺点，可采用先导式减压阀。先导式减压阀的工作原理与直动式的基本相同。先导式减压阀所用的调压气体，是由小型的直动式减压阀供给的。若把小型直动式减压阀装在阀体内部，则称为内部先导式减压阀；若将小型直动式减压阀装在主阀体外部，则称为外部先导式减压阀。
组合式减压阀
组合式减压阀是专为复杂工况下运行的供水系统量身设计的减压设备，由出口压力锁定系统，反馈统，和主阀阀体组成。组合式减压阀与常规减压阀的区别在于：
1、反馈系统互为备用可供不停机检修；
2、反冲排污系统可适用更多不佳水质；
3、出口压力锁定系统可以锁定出口压力上限；
4、减压比蕞大值可达到12:1，蕞高应用水头320米
5、蕞大过流量超过5000m³/h，蕞大应用单机800MW
