增加了一个指挥器（先导阀）它起到对反馈信号的放大作用然后通过执行机构，驱动主阀阀瓣运动达到改变阀开度的目的。

如果是压力调节阀，反馈信号就是阀的出口压力，通过信号管引入执行机构。

如果是流量调节阀，阀的出口处就有一个孔板（或者是其他阻力装置）由孔板两端取出压差信号引入执行机构。

如果是温度调节阀，阀的出口就有温度传感器（或者温包）通过温度传感器内介质的热胀冷缩驱动执行机构。

自力式调节阀依靠流经阀内介质自身的数字压力表、摄氏度作为能源驱动阀门自动工作，不需要外接电源和二次仪表。这种自力式调节阀都利用阀输出端的反馈信号源（数字压力表、压差、摄氏度）通过信号源管传递到运行组织驱动阀瓣改变阀门的开度，达到调节数字压力表、流量、摄氏度的目的。这种调节阀又分为直接功用式和间接功用式两种。

直接功用自力式调节阀又称为弹簧负载式，其结构内有弹性元件如：弹簧、波纹管、波纹管式的温包等，利用弹性力与反馈信号源平衡的原理。 如果是数字压力表自力式调节阀，反馈信号源就是阀的出口数字压力表，通过信号源管引入运行组织。 如果是流量自力式调节阀，阀的出口处就有一个孔板（或者是其他阻力装置）由孔板两端取出压差信号源引入运行组织。 如果是摄氏度自力式调节阀，阀的出口就有摄氏度传感器（或者温包）通过摄氏度传感器内介质的热胀冷缩驱动运行组织。(1) 取压点应取在调压阀适当位置，阀前调压应大于2倍管道直径，阀后调压应大于6倍管道直径。
