比例阀是一种新型的装置。在普通压力阀、流量阀和方向阀上，用比例电磁铁替代原有的控制部分，按输入的电气信号连续地、按比例地对油流的压力、流量或方向进行远距离控制。比例阀一般都具有压力补偿性能，输出压力和流量可以不受负载变化的影响
随着液压传动和的发展， 生产实践中出现一些即要求能够连续的控制 压力、流量和方向，又不需要其控制精度很 高的液压系统。由于普通的液压元件不能满 足具有一定的伺服性要求，而使用电液伺服 阀又由于控制精度要求不高而过于浪费，因 此近几年产生了介于普通液压元件 （开关控制） 和伺服阀 （连续控制） 之间的比例控制 阀。
电液比例控制阀（简称比例阀）实质上是一种廉价的、抗污染性能较好的电液控制阀。比例阀的发展经历两条途径，一是用比例电磁铁取代传统液压阀的手动调节输入机构，在传统液压阀的基础下：发展起来的各种比例方向、压力和流量阀；二是一些原电液伺服阀生产厂家在电液伺服阀的基础上，降低设计制造精度后发展起来的。DESOUTTER马头牌 6680
