節流閥是通過改變節流截面或節流長度以控制流體流量的閥門。將節流閥和單向閥并聯則可組合成單向節流閥。

節流閥和單向節流閥是簡易的流量控制閥，在定量泵液壓系統中，節流閥和溢流閥配合，可組成三種節流調速系統，即進油路節流調速系統、回油路節流調速系統和旁路節流調速系統。

節流閥沒有流量負反饋功能，不能補償由負載變化所造成的速度不穩定，一般僅用于負載變化不大或對速度穩定性要求不高的場合。

由于節流閥的流量不僅取決于節流口面積的大小，還與節流口前后的壓差有關，閥的剛度小，故只適用于執行元件負載變化很小且速度穩定性要求不高的場合。
對于執行元件負載變化大及對速度穩定性要求高的節流調速系統，必須對節流閥進行壓力補償來保持節流閥前后壓差不變，從而達到流量穩定。
