MOOG電液比例閥的發展展望
　　(1) 美國MOOG電液比例閥將滿足液壓系統高壓、大流量的發展要求，electro-hydraulic proportional valve will meet the high-pressure hydraulic systems,在其他各式閥類的比例將逐步增大，尤其是在工程機械領域，he development requirements of large flow will gradually increase in the proportion of other kinds of valves,MOOG電液比例閥的相對手動比例閥的應用份額將逐漸增大，并zui終占主導地位。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) 新結構和新功能的比例閥， new structures and new features proportional valve, 如采用開關閥作為導閥的電液比例閥、直動導控一體化設計的比例閥等開始應用于實際系統，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,并成為主流的結構之一 and become one of the mainstream structure。
　　(3) moog電液比例閥控制器的數字化、小型化、總線控制及集成于閥一體成為重要的發展方向。Electro-hydraulic proportional valve controller digitization, miniaturization, bus control and important direction of development to become integrated in the valve one
    (4) 電反饋和數字顯示的比例閥在液壓系統中的應用逐漸流行。Applications proportional valve electrical feedback and digital display in the hydraulic system is gaining popularity.
