FESTO比例阀平时是处于关闭状态，水泵启动时闸阀慢慢打开，水泵停机时，闸阀先慢慢关闭。水泵的闭闸启动和闭闸停车，可以有效的防止开泵水锤和停泵水锤，同时，减少了水泵启动时的电机负荷，水泵在零流量时的轴功率Z小，一般仅为设计轴功率的30％。闸阀的另一个功能是，当闸阀关闭时，可以为安装在闸阀与水泵之间的逆止阀等阀件和水泵提供安全的检修条件，防止压水管的水回流。
FESTO比例阀是一种不需要外加能源的执行器产品。可用于公称压力PN01,PN10.差（微）压均可分段调节.从50mm.W.C至0.1MPa.其用途十分广泛,可用于工业燃烧系统,控制两种物料,如煤气,空气流量配比,以达理想燃烧。用于氢冷发电机组密封油系封，当差压阀的低压端通大气即为微压阀（差压阀负压,端压,力为零）。
FESTO比例阀是一个依靠自身介质的压差为动力，自动控制流量的元器件，具有能够衡定流量的功能，可用来彻底解决水力失调问题。自力式流量控制阀安装简单，调节方便；使用中节能成效明显，节电25—30%，节煤15—20%，增加供热面积25—30%。有利于稳定运行，提高供暖质量。
