rexroth 比例溢流阀DBET-5X/200G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路，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。DBET-3X/100G24K4 DBET-3X/200G24K4 DBET-3X/315G24K4 DBET-3X/315G24K4-152 DBET-3X/315G24K4V DBET-3X/315YG24K4V DBET-3X/50G24K4 DBET-3X/50G24NK4-271 DBET-3X/50YG24K4 DBET-5X/100G24K4M DBET-5X/100G24K4M-1 DBET-5X/100G24K4M-27 DBET-5X/100G24K4V DBET-5X/100G24NK4M DBET-5X/100G24NK4M-1 DBET-5X/100G24NK4V DBET-5X/100YG24NK4M-1 DBET-5X/200G12K4M-1 DBET-5X/200G24K4M DBET-5X/200G24K4M-1 DBET-5X/200G24K4V-24 DBET-5X/200G24K4V-27 DBET-5X/200G24N9K4M DBET-5X/200G24N9K4M-1 DBET-5X/200G24NK4M DBET-5X/200G24NK4M-1 DBET-5X/200YG24K4M-1 DBET-5X/200YG24N9K4M-1 DBET-5X/315G12K4M-1 DBET-5X/315G24K4M DBET-5X/315G24K4M-1 DBET-5X/315G24K4M-27 DBET-5X/315G24K4V DBET-5X/315G24K4V-1 DBET-5X/315G24K4V-23 DBET-5X/315G24N9K4M DBET-5X/315G24N9K4M-1 DBET-5X/315G24N9K4V-1 DBET-5X/315G24NJM DBET-5X/315G24NK4M DBET-5X/315G24NK4M-1 DBET-5X/315G24NK4V DBET-5X/315G24NK4V-1 DBET-5X/315YG24K4M-1 DBET-5X/315YG24K4V-1 DBET-5X/315YG24NK4M-1 DBET-5X/315YG24NK4V-1 DBET-5X/350G24K4M DBET-5X/350G24K4M-1 DBET-5X/350G24K4M-26 DBET-5X/350G24K4M-27 DBET-5X/350G24K4V DBET-5X/350G24N9K4M DBET-5X/350G24N9K4M-1 DBET-5X/350G24NK4M DBET-5X/350G24NK4M-1 DBET-5X/350YG24K4M-1 DBET-5X/350YG24N9K4M-1 DBET-5X/350YG24NK4M-1 DBET-5X/400G24K4M-8 DBET-5X/400G24K4V-8 DBET-5X/400G24N9K4M-8 DBET-5X/400G24NK4M-8 DBET-5X/400YG24NK4M-14 DBET-5X/50G24K4M DBET-5X/50G24K4V DBET-5X/50G24K4V-1 DBET-5X/50G24NK4M-1 DBET-5X/50G24NK4M-16 DBET-5X/50YG24K4M-1 DBET-5X=315G24K4M=DE DBET-6X/200G24K4V DBETB-1X/180G24K4M DBETB-1X/230G24K4M DBETB-1X/230G24K4M-551 DBETB-1X/25G24K4M DBETE-5X/100G24K31M DBETE-5X/100G24K31M-1 DBETE-5X/100G24K31V DBETE-5X/100G24K31V-22 DBETE-5X/100YG24NK31M-1 DBETE-5X/200G24K31M DBETE-5X/200G24K31M=LB DBETE-5X/200G24K31M-1 DBETE-5X/200G24K31V DBETE-5X/200G24K31V-1 DBETE-5X/200G24NK31M DBETE-5X/200G24NK31M-1 DBETE-5X/200YG24K31M-1 DBETE-5X/200YG24NK31M-1 DBETE-5X/250G24K31M DBETE-5X/250G24K31M-1 DBETE-5X/250YG24K31M-1 DBETE-5X/315G24K31M DBETE-5X/315G24K31M-1 DBETE-5X/315G24K31M-20 DBETE-5X/315G24K31M-27 DBETE-5X/315G24K31V DBETE-5X/315G24K31V-21
