力士乐直动式比例溢流阀，DBETE-5X/50G24K31M*产品

德国Rexroth比例溢流阀是一种能够使所输出油液的参数（压力）随输入电信号参数（电流或电压）的变化而成比例地变化的液压控制阀。比例溢流阀与电子放大器协同工作，放大器向比例阀提供适当的驱动电流，以校准阀的调整量，使之与供给放大器的输入信号相对应。

力士乐直动式比例溢流阀不能用于高压大流量液压系统这种情况，设计了一种带补偿活塞的直动式比例溢流阀。Rexroth直动式比例溢流阀补偿活塞能够补偿电磁铁指令力，消除作用在阀芯上的液压力、摩擦力和液动力过大而指令力过小的矛盾，从而实现较强的负反馈，提高控制精度，使力士乐直动式比例溢流阀不能用于大流量液压系统的问题在理论上得到解决。

力士乐直动式比例溢流阀实际应用中一般有：作卸荷阀用，作远程调压阀，作高低压多级控制阀，作顺序阀，用于产生背压(串在回油路上)。
