Rexroth比例阀是螺纹将电磁比例插装件固定油路集成块上元件，螺旋插装阀具有应用灵活、节省管路和成本低廉等特点，近年来工程机械上应用越来越广泛。常用螺旋插装式比例阀有二通、三通、四通和多通等形式，二通式比例阀主比例节流阀，它常它元件一起构成复合阀，对流量、压力进行控制；三通式比例阀主比例减压阀，也是移动式机械液压系统中应用较多比例阀，它主对液动操作多路阀先导油路进行操作。利用三通式比例减压阀可以代替传统手动减压式先导阀，它比手动先导阀具有更多灵活性和更高控制精度。可以制成如图1所示比例伺服控制手动多路阀，不同输入信号，减压阀使输出活塞具有不同压力或流量进而实现对多路阀阀芯位移进行比例控制。
Rexroth比例阀利用车身与车桥之间的距离变化（外界作用力）来改变弹簧的预紧力，随着车辆载荷的增加，相应地进行调整，使得在任何载荷条件下都能得到一个近似理想的制动力分配。它安装在制动总泵与后轮制动分泵之间的管道上，由壳体、柱塞、阀门、弹簧等组成。壳体进油孔与制动总泵出油孔相通，出油孔与车轮制动分泵相通。当外界作用力小时，感载比例阀的柱塞在弹簧预紧力的作用下被推至zui右边，两孔相通，总泵与分泵压力相等。当外界作用力大于弹簧预紧力，迫使柱塞左移，令柱塞与阀门接触并关闭了阀门，切断总泵通向分泵的通道；若外界作用力压力继续增大，又会使柱塞右移，柱塞与阀门脱离接触，阀门又被打开，总泵与分泵又相通。这样比例阀反复动作使分泵的液压不断得到调整，也即不断调整了后轮制动力。比例阀来调节所需要的流量。这种传统的气动控制系统要想要有多个输出力和多个运动速度，就需要多个减压阀、节流阀及换向阀。这样，不仅元件需要多，成本高，构成系统复杂，且许多元件都需要预先进行人工调节。
