REXROTH比例阀是阀内比例电磁铁输入电压信号产生相应动作，使工作阀阀芯产生位移，阀口尺寸发生改变并以此完成与输入电压成比例压力、流量输出元件。阀芯位移也可以以机械、液压或电形式进行反馈。电液比例阀具有形式种类多样、容易组成使用电气及计算机控制各种电液系统、控制精度高、安装使用灵活以及抗污染能力强等多方面优点，应用领域日益拓宽。电气比例阀快易优自动化选型与收录，研发生产插装式比例阀和比例多路阀充分考虑到工程机械使用特点，具有先导控制、负载传感和压力补偿等功能。它出现对移动式液压机械整体技术水平提升具有重要意义。特别是电控先导操作、无线?？睾陀邢咭？夭僮鞯确矫嬲瓜至似淞己糜τ们熬?。
REXROTH比例阀的特点如下：
1)可实现压力、速度的无极调节，避免了常通的开关式气阀换向时的冲击现象。
2)能实现远程控制和程序控制。
3)与断续控制相比，系统简化，元件大大减少。
4)与液压比例阀相比，体积小、重量轻、结构简单、成本较低，但响应速度比液压系统慢得多，对负载变化也比较敏感。
5)使用功率小、发热少、噪声低。
6)不会发生火灾，不污染环境。受温度变化的影响小。
