德國REXROTH比例放大器對簡化工程機械操作、效率和作業(yè)精度以及實現(xiàn)智能化作業(yè)都有著極其重要意義，其性能進步和應用范疇日益拓寬必將使工程機械技巧到較大程度。

德國REXROTH比例放大器輸入電壓信號產(chǎn)生相應動作，使工作閥閥芯產(chǎn)生位移，閥口尺寸發(fā)生改變并以此完成與輸入電壓成比例壓力、流量輸出元件。閥芯位移也可以以機械、液壓或電形式進行反饋。電液比例閥形式種類多樣、容易組成使用電氣及計算機把持各種電液系統(tǒng)、把持精度高、安裝使用機動以及抗污染能力強等多方面優(yōu)點，應用領域日益拓寬。近年研發(fā)生產(chǎn)插裝式比例閥和比例多路閥充分考慮到工程機械使用特點，先導把持、負載傳感和壓力補償?shù)裙πАＫ霈F(xiàn)對移動式液壓機械整體技巧提升重要意義。特別是電控先導操作、無線遙控和有線遙控操作等方面展現(xiàn)了其良應用前景。
