REXROTH比例閥是閥內(nèi)比例電磁鐵輸入電壓信號產(chǎn)生相應(yīng)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。電液比例閥具有形式種類多樣、容易組成使用電氣及計算機控制各種電液系統(tǒng)、控制精度高、安裝使用靈活以及抗污染能力強等多方面優(yōu)點，應(yīng)用領(lǐng)域日益拓寬。電氣比例閥快易優(yōu)自動化選型與收錄，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，具有先導(dǎo)控制、負(fù)載傳感和壓力補償?shù)裙δ?。它出現(xiàn)對移動式液壓機械整體技術(shù)水平提升具有重要意義。特別是電控先導(dǎo)操作、無線遙控和有線遙控操作等方面展現(xiàn)了其良好應(yīng)用前景。
REXROTH比例閥的特點如下：
1)可實現(xiàn)壓力、速度的無極調(diào)節(jié)，避免了常通的開關(guān)式氣閥換向時的沖擊現(xiàn)象。
2)能實現(xiàn)遠(yuǎn)程控制和程序控制。
3)與斷續(xù)控制相比，系統(tǒng)簡化，元件大大減少。
4)與液壓比例閥相比，體積小、重量輕、結(jié)構(gòu)簡單、成本較低，但響應(yīng)速度比液壓系統(tǒng)慢得多，對負(fù)載變化也比較敏感。
5)使用功率小、發(fā)熱少、噪聲低。
6)不會發(fā)生火災(zāi)，不污染環(huán)境。受溫度變化的影響小。
