SMC AR系列减压阀结构原理
下图是SMC AR平衡式直动式减压阀结构原理图。阀芯的下部与二次侧压力相通，故阀芯上下所受气压力是平衡的，压力的变动（不论是一次侧还是二次侧）不影响阀芯上下气压力的平衡，故这种结构形式的压力特性好。
SMC膜片式减压阀的工作原理是：将手轮外拉，见到黄色圈后，顺时针旋转手轮，调压弹簧被压缩，推动膜片组件下移，通过阀杆，打开阀芯，则进气口压力经阀芯节流降压，有压力输出。出口压力气体经反馈管浸入膜片下腔，在膜片上产生一个向上的推力。当此推力与调压弹簧平衡时，出口压力便稳定在一定值。
逆时针旋转手轮，调压弹簧力不断减小，阀芯逐渐关闭，膜片下腔中的压缩空气，经溢流阀不断从排气孔排处，直至zui后出口压力降为零。
调压完成后，将手轮压回，手轮被锁住，以保持设定压力一定。故称为锁定型手轮。
溢流式减压阀常用于二次侧负载变动的场合，如进行频繁调整的场合、二次侧有容器（如气缸）的场合。在使用过程中，经常要从溢流孔排出少量气体。当介质为有害气体的气路中，为防止污染工作场所，应选用无溢流孔的减压阀，即非溢流式减压阀。非溢流式减压阀也常用于经常耗气的吹气系统和气马达。
