REXROTH电磁溢流阀R900926054
REXROTH电磁溢流阀R900926054 DBW10A2-52/315-6EG24N9K4；
DBW型电磁溢流阀:
此阀工作原理与DB型阀相同，只是可通过安装在先导阀上的电磁换向阀使系统在任意时刻卸荷。
DB/DBW型阀均设有控制油内部供油道和内部排油道控制油外供口和外排口。这样就可根据控制油供给和排出的不同形式的组合内供内排、外供内排、内供外排和外供外排4种型式。

液压传动
与机械传动相比。液压传动更容易实现其运动参数(流量)和动力参数(压力)的控制，而液压传动较之液力传动具有良好的低速负荷特性。由于具有传递效率高，可进行恒功率输出控制，功率利用充分，系统结构简单，输出转速无级调速，可正、反向运转，速度刚性大，动作实现容易等突出优点，液压传动在工程机械中得到了广泛的应用。几乎所有工程机械装备都能见到液压技术的踪迹，其中不少已成为主要的传动和控制方式。极限负荷调节闭式回路，发动机转速控制的恒压，恒功率组合调节的变量系统开发，给液压传动应用于工程机械行走系提供了广阔的发展前景。
