派克取力器圖片489ZLDAX-A5XD華東總：PARKER比例閥具有應用靈活、節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傳統手動減壓式先導閥，它比手動先導閥具有更多靈活性和更高控制精度。可以制成如圖1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單獨控制。 滑閥式比例閥又稱分配閥，是移動式機械液壓系統zui基本元件之一，是能實現方向與流量調節復合閥。電液滑閥式比例多路閥是比較理想電液轉換控制元件，它保留了手動多路閥基本功能，還增加了位置電反饋比例伺服操作和負載傳感等*控制手段。它是工程機械分配閥更新換代產品。
