力士樂比例溢流閥全國熱銷進行中，凡是在14年購買Rexroth比例溢流閥及比例閥。我公司都將給于客戶Z低的優(yōu)惠及的折扣，讓客戶滿意就是我們得到Z大的收獲！幫助客戶解決問題是我們獲得Z大的成就！Rexroth力士樂比例溢流閥是一種能夠使所輸出油液的參數(shù)（壓力）隨輸入電信號參數(shù)（電流或電壓）的變化而成比例地變化的液壓控制閥。

德國力士樂先導(dǎo)式溢流閥DBE6X型的特點：可通過線圈電流進行調(diào)節(jié)；技術(shù)參數(shù)和所選的電子控制單元；電磁鐵類型Imax=0.8A或者Imax=2.5A；即使當電子控制單元損壞時，也能zui大程度地實現(xiàn)過壓保護（線圈電流I＞Imax）用于閥板安裝，安裝孔符合ISO4401-03-02-0-94；符合DIN43650-AM2標準的線纜插座，包括在供貨范圍內(nèi)；具有斜坡功能和閥調(diào)節(jié)功能的外部電子控制單元。 

 

力士樂Rexroth先導(dǎo)式比例溢流閥的的工作原理：通過電子控制單元確定某個設(shè)定值，對系統(tǒng)壓力進行調(diào)節(jié)。電子控制單元根據(jù)設(shè)定值，利用穩(wěn)壓PWM電流（PWM=脈沖寬度調(diào)制）對線圈進行控制。利用震蕩信號對穩(wěn)壓電流進行調(diào)制，以保證獲得極小的滯后量。比例電磁鐵將電流轉(zhuǎn)變成機械作用力，并通過銜鐵挺桿作用于先導(dǎo)級中的主彈簧上。通過個供油孔將流量為＜0.6L/min的控制油供應(yīng)給先導(dǎo)級。通過錐孔/座孔構(gòu)造確定壓力級“Pmax”
