Rexroth比例伺服閥供貨源頭，力士樂(lè)比例伺服閥介紹：
電液比例伺服閥（也稱伺服比例閥，伺服比例閥叫的比較多）是伺服比例閥是比例技術(shù)與伺服技術(shù)結(jié)合的產(chǎn)物。它是將比例閥中的比例電磁鐵和伺服閥中的閥芯和閥套加工技術(shù)有機(jī)結(jié)合獲得的。與比例閥相比，它zui重要的特征就是當(dāng)閥芯處于中位時(shí)，閥口是零開(kāi)口的（閥口的遮蓋量幾乎為零），這意味著伺服比例閥的控制特性具有死區(qū)為零的特點(diǎn)，特別適用于作為閉環(huán)系統(tǒng)的控制元件。它可以按給定的輸入電壓或電流信號(hào)連續(xù)地按比例地遠(yuǎn)距離地控制流體的方向、壓力和流量。
采用電液比例控制閥可以提高系統(tǒng)的自動(dòng)化程度和精度，又簡(jiǎn)化了系統(tǒng)。比例閥的工作雖用伺服閥可完成，但后者精度高、價(jià)格貴，對(duì)油液清潔度要求更高。比例閥主要結(jié)構(gòu)與普通閥差別不大，只是比例閥均由比例電磁鐵驅(qū)動(dòng)（一種電—機(jī)械轉(zhuǎn)換器）。要注意到比例閥，伺服閥和伺服比例閥是三種不同類型的閥。
比例閥分為：比例壓力閥、比例流量閥和比例方向閥
電液比例伺服閥又叫電液伺服比例閥，來(lái)源于比例技術(shù)與伺服技術(shù)的結(jié)合，一種是采用比例電磁鐵作為電-機(jī)轉(zhuǎn)換器，將傳統(tǒng)電液比例閥的功率滑閥改進(jìn)成伺服閥的閥芯、閥套結(jié)構(gòu)；一種是將電液伺服閥的滑閥的閥套結(jié)構(gòu)去掉，機(jī)械反饋改為電反饋。
