減壓閥按照結(jié)構(gòu)形式和工作原理，也可以分為直動型和先導(dǎo)型兩大類。

減壓閥的工作原理是利用液體流過狹小的縫隙產(chǎn)生壓力損失，使其出口壓力低于進(jìn)口壓力的壓力控制閥。按照壓力調(diào)節(jié)要求的不同，分定值減壓閥、定差減壓閥和定比減壓閥。

(2)溢流閥。又稱閥、限壓切斷閥等，起限壓保護(hù)作用；

溢流閥是通過閥口對液壓系統(tǒng)相應(yīng)液體進(jìn)行溢流，調(diào)定系統(tǒng)的工作壓力或者限定其大工作壓力，系統(tǒng)工作壓力過載。

對溢流閥的主要要求是靜態(tài)、動態(tài)特性好。靜態(tài)特性是指壓力——流量特性好。動態(tài)特性是指突加外界干擾后，工作穩(wěn)定、壓力超調(diào)量小、溢流響應(yīng)快。
