节流阀是通过改变节流截面或节流长度以控制流体流量的阀门。将节流阀和单向阀并联则可组合成单向节流阀。
节流阀和单向节流阀是简易的流量控制阀，在定量泵液压系统中，节流阀和溢流阀配合，可组成三种节流调速系统，即进油路节流调速系统、回油路节流调速系统和旁路节流调速系统。节流阀没有流量负反馈功能，不能补偿由负载变化所造成的速度不稳定，一般仅用于负载变化不大或对速度稳定性要求不高的场合。

液压元件可分为动力元件和控制元件以及执行元件三大类。尽管都是液压元件，它们的自身功能和安装使用的技术要求也不尽相同，现分别介绍如下：
动力元件：指的是各种液压泵，齿轮泵、叶片泵、柱塞泵、螺杆泵。
1、齿轮油泵和串联泵（包括外啮合与内啮合）两种结构型式。
2、叶片油泵（包括单级泵、变量泵、双级泵、双联泵）。
3、柱塞油泵，又分为轴向柱塞油泵和径向柱塞油泵，轴向柱塞泵有定量泵、变量泵、

由于节流阀的流量不仅取决于节流口面积的大小，还与节流口前后的压差有关，阀的刚度小，故只适用于执行元件负载变化很小且速度稳定性要求不高的场合。 对于执行元件负载变化大及对速度稳定性要求高的节流调速系统，必须对节流阀进行压力补偿来保持节流阀前后压差不变，从而达到流量稳定
