美國派克D41VW3C2NUW89比例閥
輸入信號增大，供氣用電磁閥先導閥1換向，而排氣用電磁先導閥7處于復位狀態(tài)，則供氣壓力從SUP口通過(guò)閥1進(jìn)入先導室5，先導室壓力上升，氣壓力作用在膜片2的上方，則和膜片2相連的供氣閥芯4便開(kāi)啟，排氣閥芯3關(guān)閉，產(chǎn)生輸出壓力。此輸出壓力通過(guò)壓力傳感器6反饋至控制回路8。在這里，與目標值進(jìn)行快速比較修正，知道輸出壓力與輸入信號成一定比例為止，從而得到輸出壓力與輸入信號的變化成比例的變化。由于沒(méi)有噴嘴擋板機構，故閥對雜質(zhì)不敏感，可靠性高。
美國派克比例閥特點(diǎn)
可實(shí)現壓力、速度的無(wú)極調節，避免了常通的開(kāi)關(guān)式氣閥換向時(shí)的沖擊現象。
能實(shí)現遠程控制和程序控制。與斷續控制相比，系統簡(jiǎn)化，元件大大減少。與液壓比例閥相比，體積小、重量輕、結構簡(jiǎn)單、成本較低，但響應速度比液壓系統慢得多，對負載變化也比較敏感。使用功率小、發(fā)熱少、噪聲低。不會(huì )發(fā)生火災，*。受溫度變化的影響小。
