调节阀用于调节介质的流量、压力和液位。根据调节部位信号，自动控制阀门的开度，从而达到介质流量、压力和液位的调节。调节阀分电动调节阀、气动调节阀和液动调节阀等。本手册主要介绍电动调节阀和气动调节阀两种。
调节阀由电动执行机构或气动执行机构和调节阀两部分组成。调节并通常分为直通单座式和直通双座式两种，后者具有流通能力大、不平衡办小和操作稳定的特点，所以通常特别适用于大流量、高压降和泄漏少的场合。
流通能力Cv是选择调节阀的主要参数之一，调节阀的流通能力的定义为：当调节阀全开时，阀两端压差为0.1MPa，流体密度为1g/cm3 时，每小时流径调节阀的流量数，称为流通能力，也称流量系数，以Cv表示，单位为t/h，液体的Cv值按下式计算。
根据流通能力Cv值大小查表，就可以确定调节阀的公称通径DN。
