螺旋插裝式比例閥是螺紋將電磁比例插裝件固定油路集成塊上元件，螺旋插裝閥具有應用靈活、節(jié)省管路和成本低廉等特點，近年來工程機械上應用越來越廣泛。常用螺旋插裝式比例閥有二通、三通、四通和多通等形式，二通式比例閥主比例節(jié)流閥，它常它元件一起構成復合閥，對流量、壓力進行控制；三通式比例閥主比例減壓閥，也是移動式機械液壓系統(tǒng)中應用較多比例閥，它主對液動操作多路閥先導油路進行操作。利用三通式比例減壓閥可以代替?zhèn)鹘y(tǒng)手動減壓式先導閥，它比手動先導閥具有更多靈活性和更高控制精度?？梢灾瞥扇鐖D1所示比例伺服控制手動多路閥，不同輸入信號，減壓閥使輸出活塞具有不同壓力或流量進而實現(xiàn)對多路閥閥芯位移進行比例控制。四通或多通螺旋插裝式比例閥可以對工作裝置實現(xiàn)單獨控制。
