先使系统安全阀全开，比例溢流阀输入电流为零，再起泵。然后保持安全阀为零，给比例阀输入最大电流 .慢慢调节手调安全阀的手柄，使系统压力逐步上升，将比例阀输入电流降下来，直到系统需要的最高压力，记录对应当输入电流数值。这就是系统要求的最高压力说对应的电流，如果用计算机控制或用信号发生器输入，将这个电流最为输入电流的限制值。

定流量阀和横流量调节阀都是变阻力设备，它们是以流体的差压作为动力，并根据系统工况（差压）变化，自动改变阻力系数，保持流量阀和横流量的恒定，通过恒定各个支路的流量来实现整个系统流量的均衡输配，消除冷热不均的现象。在总流量足够的条件下，各个支路的流量变化不会互相影响，系统比较稳定。
