意大利ATOS伺服比例閥專業(yè)代理比例伺服閥（簡稱比例閥）是由比例電磁鐵取代普通液壓閥的調(diào)節(jié)和控制裝置而構(gòu)成的。它可以按給定的輸入電壓或電流信號連續(xù)地按比例地遠距離地控制流體的方向、壓力和流量。 　　采用電液比例控制閥提高了系統(tǒng)的自動化程度和精度，又簡化了系統(tǒng)。 　　比例閥的工作雖用伺服閥可完成，但后者精度高、價格貴，對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（一種電—機械轉(zhuǎn)換器）。 　　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，來源于比例技術與伺服技術的結(jié)合，一種是采用比例電磁鐵作為電-機轉(zhuǎn)換器，將傳統(tǒng)電液比例閥的功率滑閥改進成伺服閥的閥芯、閥套結(jié)構(gòu)；一種是將電液伺服閥的意大利ATOS伺服比例閥專業(yè)代理滑閥的閥套結(jié)構(gòu)去掉，機械反饋改為電反饋。伺服比例閥
