意大利ATOS伺服比例閥專業代理比例伺服閥（簡稱比例閥）是由比例電磁鐵取代普通液壓閥的調節和控制裝置而構成的。它可以按給定的輸入電壓或電流信號連續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的自動化程度和精度，又簡化了系統。 　　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。比例閥主要結構與普通閥差別不大，只是比例閥均由比例電磁鐵驅動（一種電—機械轉換器）。 　　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合，一種是采用比例電磁鐵作為電-機轉換器，將傳統電液比例閥的功率滑閥改進成伺服閥的閥芯、閥套結構；一種是將電液伺服閥的意大利ATOS伺服比例閥專業代理滑閥的閥套結構去掉，機械反饋改為電反饋。伺服比例閥
