MOOG电液比例阀的发展展望
　　(1) 美国MOOG电液比例阀将满足液压系统高压、大流量的发展要求，electro-hydraulic proportional valve will meet the high-pressure hydraulic systems,在其他各式阀类的比例将逐步增大，尤其是在工程机械领域，he development requirements of large flow will gradually increase in the proportion of other kinds of valves,MOOG电液比例阀的相对手动比例阀的应用份额将逐渐增大，并zui终占主导地位。especially in the field of mechanical engineering, the relative proportion of electro-hydraulic proportional valve manual valve applications share will gradually increase and eventually dominate.
　　(2) 新结构和新功能的比例阀， new structures and new features proportional valve, 如采用开关阀作为导阀的电液比例阀、直动导控一体化设计的比例阀等开始应用于实际系统，such as the use of on-off valve as a pilot valve electro-hydraulic proportional valve, direct acting guide the design of proportional valve control integration began to be used,并成为主流的结构之一 and become one of the mainstream structure。
　　(3) moog电液比例阀控制器的数字化、小型化、总线控制及集成于阀一体成为重要的发展方向。Electro-hydraulic proportional valve controller digitization, miniaturization, bus control and important direction of development to become integrated in the valve one
    (4) 电反馈和数字显示的比例阀在液压系统中的应用逐渐流行。Applications proportional valve electrical feedback and digital display in the hydraulic system is gaining popularity.
