由油缸、阀体两部分组成。而节流孔板和高压调节阀设计为一体，阀门开关排泄流量和降压由液压缸行程控制。能任意调整排泄压力及流量，，方便。
比例减压阀：压降从50兆帕于1.6兆帕，可以调节排泄压力。

比例阀是按比例控制的，他的控制器实际是一个放大器，主要用于加强系统的调节作用，增益K越大，调节作用越强，系统的响应性越好，但K值过大也会导致系统不稳定。比例控制存在稳态误差，增大K可减小稳态误差，但不能。对于干扰较大、惯性较大的系统，不宜采用比例控制。
积分阀是靠积分控制的，他是在比例的控制上加上积分控制，既可以系统的响应性，又可以系统的稳态误差，使系统的稳定性和动态精度都得到，这个应用。
所以说他们之间的区别是他们分别所用的控制方式的不同。
