APTECH调压阀作用原理：工作时，假定出口压力小于指挥器控制弹簧的设定值，指挥器控制弹簧的力然后克服出口压异常控制条件下要求主阀快速关闭时，泄压阀打开以增加泄压速度。作用到主阀膜片上数值增加后的出口压力加上主阀弹簧的弹力，就能克服作用到主阀膜片上数值减小的加载压力，将节流套推向静止阀座，使流向下游系统的气量减少

APTECH调压阀三个结构特点：

　　1、调压阀的本体带导叶消能和补气的阀壳、锥型或圆形的阀盘、平衡腔、接力器、引导油腔、活塞行程限制环、进排水管和补气阀等组成.接力器及引导油腔直接与阀壳连成整体,体积小,结构简单,布置紧凑.

　　2、流量特性.根据调压阀的阀塞类型和Yx/Dx值查询单位流量得到调压阀的相应流量Q,从而可以绘制出各种调压阀的开度与流量关系曲线.

　　3、操作特性.调压阀低操作油压的范围随着调压阀工作水头的提高而提高。
