德國(guó)力士樂(lè)先導(dǎo)式溢流閥DBE6X型的特點(diǎn)：可通過(guò)線圈電流進(jìn)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(dāng)電子控制單元損壞時(shí)，也能zui大程度地實(shí)現(xiàn)過(guò)壓保護(hù)（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(biāo)準(zhǔn)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(lè)Rexroth先導(dǎo)式比例溢流閥的的工作原理：通過(guò)電子控制單元確定某個(gè)設(shè)定值，對(duì)系統(tǒng)壓力進(jìn)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(duì)線圈進(jìn)行控制。利用震蕩信號(hào)對(duì)穩(wěn)壓電流進(jìn)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(jī)械作用力，并通過(guò)銜鐵挺桿作用于先導(dǎo)級(jí)中的主彈簧上。通過(guò)個(gè)供油孔將流量為＜0.6L/min的控制油供應(yīng)給先導(dǎo)級(jí)。通過(guò)錐孔/座孔構(gòu)造確定壓力級(jí)“Pmax”
