比例阀对流量的控制可以分为两种：
一种是开关控制：要么全开、要么全关，流量要么大、要么小，没有中间状态，如普通的电磁直通阀、电磁换向阀、电液换向阀。
另一种是连续控制：阀口可以根据需要打开任意一个开度，由此控制通过流量的大小，这类阀有手动控制的，如节流阀，也有电控的，如比例阀、伺服阀。
所以使用比例阀或伺服阀的目的就是：以电控方式实现对流量的节流控制（当然经过结构上的改动也可实现压力控制等），既然是节流控制，就必然有能量损失，伺服阀和其它阀不同的是，它的能量损失更大一些，因为它需要一定的流量来维持前置级控制油路的工作。
比例阀是气流只能一个方向流动而不能反向流动的方向控制阀。其工作原理与液压单向阀一样。压缩空气从P口进入，克服弹簧力和摩擦力使单向阀阀口开启，压缩空气从P流至A；当P口无压缩空气时，在弹簧力和A口（腔）余气力作用下；阀口处于关闭状态，使从A至P气流不通。
比例阀应用于不允许气流反向流动的场合，如空压机向气罐充气时，在空压机与气罐之间设置一单向阀，当空压机停止工作时，可防止气罐中的压缩空气回流到空压机。比例阀还常与节流阀、顺序阀等组合成比例阀使用。

力士乐REXROTH伺服电磁阀四位四通高频单向阀门，直接驱动，带有集成电子和电气位置反馈（OBE）4WRPEH 6 -3X
比例阀的输入单元是电-机械转换器,它将输入的电信号转换成机械量转换器有伺服电机和步进电机力马达和力矩马达比例电磁铁等形式。但常用的比例阀大都采用了比例电磁铁，比例电磁铁根据电磁原理设计,能使其产生的机械量(力或力矩和位移)与输入电信号(电流)的大小成比例,再连续地控制液压阀阀芯的位置，进而实现连续地控制液压系统的压力方向和流量。比例电磁铁的结构，它由线圈、衔铁推杆等组成,当有信号输入线圈时,线圈内磁场对衔铁产生作用力,衔铁在磁场中按信号电流的大小和方向成比例连续地运动,再通过固连在一起的销钉带动推杆运动,从而控制滑阀阀芯的运动。

电磁阀如何选型及安装注意哪些事项
工作原理：1.直动式电磁阀原理：常闭型直动式电磁阀通电时，电磁线圈产生电磁吸力把阀芯提起，使阀芯上密封件离开阀座口、阀门打开；断电时，电磁力消失，靠弹簧力把阀芯上密封件压在阀座口上、阀门关闭。(常开型与此相反)特点：在真空、负压、零压差时能正常工作，阀口径越大，电磁头体积和功率就越大。如德特森公司引进技术生产的直动电磁阀可用于1.33×10-4 Mpa真空。2.分步直动式电磁阀 (即反冲型)原理：
