利用调节阀芯和阀体间的节流口面积和它所产生的局部阻力对流量进行调节，从而控制执行元件的运动速度。流量控制阀按用途分为5种。（1）节流阀：在调定节流口面积后，能使载荷压力变化不大和运动均匀性要求不高的执行元件的运动速度基本上保持稳定。（2）调速阀：在载荷压力变化时能保持节流阀的进出口压差为定值。这样，在节流口面积调定以后，不论载荷压力如何变化，调速阀都能保持通过节流阀的流量不变，从而使执行元件的运动速度稳定。（3）分流阀：不论载荷大小，能使同一油源的两个执行元件得到相等流量的为等量分流阀或同步阀；得到按比例分配流量的为比例分流阀。（4）集流阀：作用与分流阀相反，使流入集流阀的流量按比例分配。（5）分流集流阀：兼具分流阀和集流阀两种功能。
