代理德國(guó)REXROTH比例伺服閥低價(jià)供應(yīng)
力士樂Rexroth伺服閥液控伺服閥主要是指電液伺服閥,它在接受電氣模擬信號(hào)后，相應(yīng)輸出調(diào)制的流量和壓力。它既是電液轉(zhuǎn)換元件，也是功率放大元件，它能夠?qū)⑿」β实奈⑷蹼姎廨斎胄盘?hào)轉(zhuǎn)換為大功率的液壓能（流量和壓力）輸出。在電液伺服系統(tǒng)中，它將電氣部分與液壓部分連接起來，實(shí)現(xiàn)電液信號(hào)的轉(zhuǎn)換與液壓放大。電液伺服閥是電液伺服系統(tǒng)控制的核心。
力士樂Rexroth閥對(duì)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zui大、要么zui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(gè)開度，由此控制通過流量的大小，這類閥有手動(dòng)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(shí)現(xiàn)對(duì)流量的節(jié)流控制（當(dāng)然經(jīng)過結(jié)構(gòu)上的改動(dòng)也可實(shí)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?yàn)樗枰欢ǖ牧髁縼砭S持前置級(jí)控制油路的工作。
