　　先导式溢流阀的特点是用先导阀控制主阀，在溢流阀主阀溢流时，溢流阀进口压力可维持为由先导阀弹簧所调定的定值。先导式溢流阀的另一特点是具有远程控制口，可很方便地实现系统卸荷或远程调压。
先导式溢流是由先导阀和主阀组成。先导阀实际上是一个小流量直动型溢流阀，其阀芯为锥阀。主阀芯上有一阻尼孔，且上腔作用面积略大于下腔作用面积，其弹簧只在阀口关闭时起复位作用。
比例溢流阀是一种闭环智能控制的溢流阀，其执行器可以根据控制器发出的模拟信号来调整阀门开度，是使系统的控制参数自动保持在设定的范围内。
普通溢流阀与比例溢流阀一样，都有一个阀芯，阀芯的一端是液压油产生的压力，另一端是机械力。普通溢流阀通过调节弹簧力，来调整液压压力。而比例溢流阀是电磁铁直接产生推力，作用在阀芯上，电磁铁上的输入电压可以在0-24伏之间变化，产生的推力就随之变化，从而得到连续变化的液压压力。
因为比例电磁铁的推力不大，所以直动式比例溢流阀的流量很小，压力70兆帕时，流量只有1升/分钟左右。需要大流量比例阀的时候，要把这个比例阀做先导阀，下面还要配一个大通径的溢流阀。R901115195 M-3SEW6C3X/420MG24N9K4QMAG24/P

二、减压阀
减压阀是利用液流流过缝隙产生压力损失，使其出口压力低于进口压力的压力控制阀。
按调节要求不同，有定值减压阀，定差减压阀，定比减压阀。其中定值减压阀应用广，又简称减压阀。
减压阀由压力先导阀和主阀组成。出口压力油引至主阀芯上腔和先导阀前腔，当出口压力大于减压阀的调定压力时，先导阀开启，主阀芯上移，减压缝隙关小，减压阀才起减压作用且保证出口压力为定值。
减压阀与溢流阀的主要区别为：0811404571 4WRLE27Q5-430M-3X/G24EK0/A1WG02M
