意大利ATOS伺服比例阀专业代理比例伺服阀（简称比例阀）是由比例电磁铁取代普通液压阀的调节和控制装置而构成的。它可以按给定的输入电压或电流信号连续地按比例地远距离地控制流体的方向、压力和流量。 　　采用电液比例控制阀提高了系统的自动化程度和精度，又简化了系统。 　　比例阀的工作虽用伺服阀可完成，但后者精度高、价格贵，对油液清洁度要求更高。比例阀主要结构与普通阀差别不大，只是比例阀均由比例电磁铁驱动（一种电—机械转换器）。 　　比例阀分为：比例压力阀、比例流量阀和比例方向阀 　　
电液比例伺服阀又叫电液伺服比例阀，来源于比例技术与伺服技术的结合，一种是采用比例电磁铁作为电-机转换器，将传统电液比例阀的功率滑阀改进成伺服阀的阀芯、阀套结构；一种是将电液伺服阀的意大利ATOS伺服比例阀专业代理滑阀的阀套结构去掉，机械反馈改为电反馈。伺服比例阀
