力士樂比例閥4WRTE25E220L-4X/6EG24K31/A1M   REXROTH力士樂換向閥，REXROTH力士樂電磁閥 由上海韋米機電設(shè)備有限公司專業(yè)提供

換向閥是具有兩種以上流動形式和兩個以上油口的方向控制閥。是實現(xiàn)液壓油流的溝通、切斷和換向，以及壓力卸載和順序動作控制的閥門。
可分為手動換向閥、電磁換向閥、電液換向閥等。
又稱克里斯閥，閥門的一種，具有多向可調(diào)的通道，可適時改變流體流向。
工作時借著閥外的驅(qū)動傳動機構(gòu)轉(zhuǎn)動驅(qū)動軸，帶動搖拐臂，啟動閥板，使工作流體時而從左入口通向閥的下部出口，時而從右入口變換通向下部出口，實現(xiàn)了周期變換流向的目的。
這種變換閥在石油、化工生產(chǎn)中有著廣泛的應(yīng)用，在合成氨造氣系統(tǒng)中最為常用。此外，換向閥還可作成閥瓣式的結(jié)構(gòu)，多用于較小流量的場合。工作時只需轉(zhuǎn)動手輪通過閥瓣來變換工作流體的流向。

比例閥 閥對流量的控制可以分為兩種：
一種是開關(guān)控制：要么全開、要么全關(guān)，流量要么、要么小，沒有中間狀態(tài)，如普通的電磁直通閥、電磁換向閥、電液換向閥。
另一種是連續(xù)控制：閥口可以根據(jù)需要打開任意一個開度，由此控制通過流量的大小，這類閥有手動控制的，如節(jié)流閥，也有電控的，如比例閥、伺服閥。
所以使用比例閥或伺服閥的目的就是：以電控方式實現(xiàn)對流量的節(jié)流控制（當(dāng)然經(jīng)過結(jié)構(gòu)上的改動也可實現(xiàn)壓力控制等），既然是節(jié)流控制，就必然有能量損失，伺服閥和其它閥不同的是，它的能量損失更大一些，因為它需要一定的流量來維持前置級控制油路的工作。
