REXROTH二位四通換向閥*REXROTH二位四(si)(si)通(tong)換(huan)(huan)向(xiang)(xiang)閥(fa)(fa)(fa)是(shi)利用(yong)(yong)電(dian)(dian)磁鐵吸力(li)推動(dong)閥(fa)(fa)(fa)芯來改(gai)變閥(fa)(fa)(fa)的(de)工作(zuo)(zuo)位置。由(you)于它可(ke)借助于按鈕開(kai)關(guan)、行(xing)程開(kai)關(guan)、限位開(kai)關(guan)、壓(ya)力(li)繼電(dian)(dian)器等發出的(de)信號進行(xing)控制(zhi)，所(suo)以(yi)操作(zuo)(zuo)輕便，易于實現(xian)自動(dong)化，因此應用(yong)(yong)廣泛。REXROTH二位四(si)(si)通(tong)換(huan)(huan)向(xiang)(xiang)閥(fa)(fa)(fa)是(shi)電(dian)(dian)磁換(huan)(huan)向(xiang)(xiang)閥(fa)(fa)(fa)和液(ye)(ye)動(dong)換(huan)(huan)向(xiang)(xiang)閥(fa)(fa)(fa)的(de)組合(he)。其(qi)中，電(dian)(dian)磁換(huan)(huan)向(xiang)(xiang)閥(fa)(fa)(fa)起先導作(zuo)(zuo)用(yong)(yong)，控制(zhi)液(ye)(ye)動(dong)換(huan)(huan)向(xiang)(xiang)閥(fa)(fa)(fa)的(de)動(dong)作(zuo)(zuo)，改(gai)變液(ye)(ye)動(dong)換(huan)(huan)向(xiang)(xiang)閥(fa)(fa)(fa)的(de)工作(zuo)(zuo)位置;液(ye)(ye)動(dong)換(huan)(huan)向(xiang)(xiang)閥(fa)(fa)(fa)作(zuo)(zuo)為主閥(fa)(fa)(fa)，用(yong)(yong)于控制(zhi)液(ye)(ye)壓(ya)系(xi)統中的(de)執(zhi)行(xing)元件。由(you)于液(ye)(ye)壓(ya)力(li)的(de)驅動(dong)，主閥(fa)(fa)(fa)芯的(de)尺(chi)寸(cun)可(ke)以(yi)做得很大，允許大流(liu)量(liang)通(tong)過。因此，電(dian)(dian)液(ye)(ye)換(huan)(huan)向(xiang)(xiang)閥(fa)(fa)(fa)主要用(yong)(yong)在流(liu)量(liang)超(chao)過電(dian)(dian)磁換(huan)(huan)向(xiang)(xiang)閥(fa)(fa)(fa)額定流(liu)量(liang)的(de)液(ye)(ye)壓(ya)系(xi)統中，從而(er)用(yong)(yong)較小的(de)電(dian)(dian)磁鐵就能控制(zhi)較大的(de)流(liu)量(liang)。電(dian)(dian)液(ye)(ye)換(huan)(huan)向(xiang)(xiang)閥(fa)(fa)(fa)的(de)使用(yong)(yong)方(fang)法與電(dian)(dian)磁換(huan)(huan)向(xiang)(xiang)閥(fa)(fa)(fa)相同。

Rexroth力(li)士樂電液換向閥有彈簧(huang)對中(zhong)和液壓對中(zhong)兩種(zhong)型式(shi)。若按(an)控(kong)制壓力(li)油(you)及其回(hui)(hui)(hui)油(you)方式(shi)進(jin)行分類則有：外(wai)部(bu)(bu)控(kong)制、外(wai)部(bu)(bu)回(hui)(hui)(hui)油(you);外(wai)部(bu)(bu)控(kong)制、內(nei)部(bu)(bu)回(hui)(hui)(hui)油(you);內(nei)部(bu)(bu)控(kong)制、外(wai)部(bu)(bu)回(hui)(hui)(hui)油(you);內(nei)部(bu)(bu)控(kong)制、內(nei)部(bu)(bu)回(hui)(hui)(hui)油(you)等四種(zhong)類型。
