力士乐比例流量阀由比例电磁铁和流量阀组合而成。比例电磁铁与节流阀组合，称为比例节流阀，与调速阀组合称为比例调速阀，与单向调速阀组合称为比例单向调速阀。

力士乐比例流量阀工作原理图。主阀为压力补偿调速阀，节流阀阀芯3与比例电磁铁1的推杆2相连。当有电信号输入时，节流阀阀芯3在比例电磁铁l的电磁力作用下，通过推杆2与阀芯左端的弹簧5相平衡，此时对应的节流口开度h为一定值，当输入不同信号电流时，便有不同的节流口开度。由于南通监控等差减压阀4节流阀进、出口压力差不变，所以通过对应的节流口开度的流量也恒定。若输入的信号电流是连续按比例地，或按一定程序改变，则电液比例调速阀所控制的流量也就连续地按比例地，或按一定程度改变，以实现对执行元件的速度调节。

力士乐比例流量阀的一个应用实例，用于转塔车床的进给系统。所示为用普通调速阀实现三种进给速度的系统图，三个调速阀并联在油路中，并采用了一个非标准的三位四通电磁换向阀，控制工序问的有调速。用电液比例调速阀的进给系统，只要输入对应于各种速度的信号电流，就可以进行多种速度控制。比较两个液压系统，显然后者液压元件较少，系统简单，但电气复杂一些。

电液比例阀主要用于多工位加工机床，注射成型机、仿丝棉等的液压系统的速度控制，也可用于远距离速度控制和速度自动控制系统中。当输入信号电流为零时，输出流量为零，因此可做为切断油路的开关。
