   4WRLE10...35E./W.由(you) 3 個主(zhu)要部(bu)件構成：先導閥，配有控(kong)制控(kong)制閥芯和(he)閥套、回位(wei)彈簧、控(kong)制電(dian)磁鐵和(he)感應式(shi)位(wei)移傳感器；主(zhu)級，配有對中彈簧和(he)位(wei)置反饋器；集成式(shi)電(dian)子控(kong)制器。

    當(dang)沒有(you)操動控(kong)(kong)制(zhi)(zhi)電磁(ci)(ci)鐵(tie)時，先導閥(fa)的(de)(de)(de)控(kong)(kong)制(zhi)(zhi)滑閥(fa)在彈(dan)簧力作(zuo)用(yong)下處在“Fail-Safe”功能位(wei)置(zhi)中(zhong)，主級(ji)滑閥(fa)處在其(qi)彈(dan)簧對(dui)中(zhong)的(de)(de)(de)中(zhong)間位(wei)置(zhi)。在集成電子(zi)控(kong)(kong)制(zhi)(zhi)器中(zhong)將(jiang)設定值與主級(ji)控(kong)(kong)制(zhi)(zhi)滑閥(fa)的(de)(de)(de)位(wei)置(zhi)實際值進(jin)行比較。如(ru)(ru)果存在控(kong)(kong)制(zhi)(zhi)偏(pian)差，就會(hui)驅動控(kong)(kong)制(zhi)(zhi)電磁(ci)(ci)鐵(tie)，以(yi)改(gai)變磁(ci)(ci)力的(de)(de)(de)方式對(dui)先導滑閥(fa)進(jin)行調(diao)整。 經(jing)過(guo)控(kong)(kong)制(zhi)(zhi)截(jie)面的(de)(de)(de)體積流(liu)量使(shi)得主控(kong)(kong)制(zhi)(zhi)滑閥(fa)移動，相(xiang)對(dui)于設定值0.5...10V以(yi)20...100％比例調(diao)節其(qi)行程。如(ru)(ru)果設定值＜±0.5 V，則主級(ji)的(de)(de)(de)控(kong)(kong)制(zhi)(zhi)滑閥(fa)就會(hui)在對(dui)中(zhong)彈(dan)簧作(zuo)用(yong)下保持在被(bei)遮蓋的(de)(de)(de)中(zhong)間位(wei)置(zhi)。要(yao)么在內(nei)部通(tong)(tong)過(guo)接(jie)口P，或者在外(wai)部通(tong)(tong)過(guo)接(jie)口X將(jiang)控(kong)(kong)制(zhi)(zhi)油供(gong)應給先導閥(fa)。可以(yi)在內(nei)部通(tong)(tong)過(guo)接(jie)口T或者在外(wai)部通(tong)(tong)過(guo)接(jie)口Y回流(liu)到(dao)油箱。

   如(ru)果發生故(gu)障，或(huo)者當電纜斷(duan)線時(shi)，集成式電子控(kong)制(zhi)器就將控(kong)制(zhi)電磁鐵斷(duan)電，先導滑(hua)閥進入“Fail-Safe”功能(neng)位(wei)置，并且將主級(ji)的控(kong)制(zhi)油腔卸空。 主級(ji)控(kong)制(zhi)滑(hua)閥在(zai)彈簧作用(yong)下進入中(zhong)間位(wei)置。

    可將4/3-伺服換向閥(fa)與壓(ya)力補(bu)償(chang)元(yuan)件(jian)組(zu)合使用，以便補(bu)償(chang)負(fu)荷壓(ya)力或(huo)者入(ru)口壓(ya)力的(de)波(bo)動。 若為NG10、35，則通過一個轉換閥(fa)平衡負(fu)荷。 若為NG16、25 和 27，則通過兩個附加接口C1和C2。這樣即使是負(fu)流量負(fu)荷，壓(ya)力補(bu)償(chang)元(yuan)件(jian)也可始(shi)終(zhong)獲得正(zheng)確(que)的(de)壓(ya)力信號。當使用壓(ya)力補(bu)償(chang)元(yuan)件(jian)時，應當針(zhen)對閥(fa)來選用外部控制油供應。

    4WRLE10...35E./W.的(de)zui大工(gong)作壓力P, A, B 350 bar (NG27: 280 bar)和額定體積流量 50...1100 l/min (?p = 10 bar)。我們力士樂人魚您心(xin)連(lian)心(xin)，同心(xin)同德一路(lu)攜手繼(ji)續前行，創造更美好的(de)明天(tian)！
