压力控制阀是指用来对液压系统中液流的压力进行控制与调节的阀。此类阀是利用作用在阀芯上的液体压力和弹簧力相平衡的原理来工作的。

在液压传动系统中，控制油液压力高低的液压阀称为压力控制阀，简称压力阀。这类阀的共同点是利用作用在阀芯上的液压力和弹簧力相平衡的原理工作。
压力控制阀在系统中起调压、定压作用，它是利用控制油同弹簧相平衡的原理工作的，其工作状态直接受控制压力的影响，其状态是变化的。搞清各类压力阀的结构，便于掌握不同工况下阀的工作特性。
在具体的液压系统中，根据工作需要，对压力控制的要求是各不相同的：有的需要限制液压系统的高压力，如安全阀；有的需要稳定液压系统中某处的压力值（或者压力差、压力比等），如溢流阀、减压阀等定压阀；还有的利用液压力作为信号控制其动作，如顺序阀、压力继电器等。
