Rexroth双液控单向阀和其它专用器件技术进步使工程车辆挡位、转向、制动和工作装置等各种系统电气控制成为现实。一般需要位移输出机构可采用类似于图1 比例伺服控制手动多路阀驱动器完成。电气操作具有响应快、布线灵活、可实现集成控制和与计算机接口容易等优点，现代工程机械液压阀已越来越多采用电控先导控制电液比例阀（或电液开关阀）代替手动直接操作或液压先导控制多路阀。采用电液比例阀（或电液开关阀）另一个显著优点是工程车辆上可以大大减少操作手柄个数，这使驾驶室布置简洁，能够有效降低操作复杂性，对提高作业质量和效率都具有重要实际意义。力士乐单向阀型号，序列号列举：R900301889 M-SR 6 KD05-1X/
