螺旋插装式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。四通或多通螺旋插装式比例阀可以对工作装置实现单独控制。
