ATOS阿托斯比例流量控制閥的基本原理：相應的參考信號產生對應的電磁鐵吸力，電磁鐵吸力作用在靠彈簧復位的閥芯上，驅動閥芯運動，從而實現要求的液壓參數調節。

       阿托斯QVHZO和QVKZOR為二通或三通直動式比例流量閥，帶位置傳感器，根據輸入型號的大小提供流量補償控制。RZGO-AES-PS-033/315比例減壓閥-特價ATOS阿托斯Atso比例流量閥與電子放大器配合工作，意大利ATOS電子放大器對比例閥提供一適量電流信號，以校準閥的調整量，使之與供給ATOS電子放大器的輸入信號相對應。

       ATOS阿托斯比例流量控制閥QVHZO和QVKZOR型比例流量控制閥的流量分別為45L/min和90L/min和zui大壓力為210bar。ATOS設計制造各種比例、伺服液壓系統及油缸總成。產品廣泛應用于礦山、冶金、電力、汽車、環保機械等多個領域。

       ATOS比例流量控制閥是將流量閥與比例裝置組成的、流量與控制信號成比例的閥。RZGO-AES-PS-033/315比例減壓閥-特價ATOS阿托斯是以提動桿外裝置的電磁線圈所產生的電磁力來控制流量閥的開口大小。由于電磁線圈有良好的線性度，故其產生的電磁力是和電流的大小成正比，在應用時可以產生連續變化的電流，從而可任意控制流量閥的開口大小。

       RZGO-AES-PS-033/315比例減壓閥-特價ATOS阿托斯的工作原理：下圖所示為比例閥工作原理框圖。指令信號經比例放大器進行功率放大，并按比例輸出電流給比例閥的比例電磁鐵，比例電磁鐵輸出力并按比例移動閥芯的位置，即可按比例控制液流的流量和改變液流的方向，從而實現對執行機構的位置或速度控制。在某些對位置或速度精度要求較高的應用場合，還可通過對執行機構的位移或速度檢測，構成閉環控制系統。比例閥由直流比例電磁鐵與液壓閥兩部分組成，比例閥實現連續控制的核心是采用了比例電磁鐵，比例電磁鐵種類繁多，但工作原理基本相同，它們都是根據比例閥的控制需要開發出來的。

       RZGO-AES-PS-033/315比例減壓閥-特價ATOS阿托斯ATOS按比例閥控制方式分類是指按照比例閥的先導控制閥中的電氣一機械轉換方式來分類，其電控制部分有比例電磁鐵、力矩馬達、直流伺服電動機等多種形式。

     （1）電磁式電磁式是指采用比例電磁鐵作為電氣一機械轉換元件的比例閥，比例電磁鐵將輸入的電流信號轉換成力、位移機械信號輸出．進而控制壓力、流量及方向等參數。

     （2）電動式電動式是指采用直流伺服電動機作為電氣一機械轉換元件的比例閥，直流伺服電動機將輸入的電信號．轉換成旋轉運動轉速，再經絲桿螺母、齒輪齒條或齒輪凸輪等減速裝置和變換機構，輸出力與位移，進一步控制液壓參數。

     （3）電液式電液式是指采用力矩馬達和噴嘴擋板的結構為先導控制級的比例閥。對力矩馬達輸入不同的電信號，并通過同它連接在一起的擋板（有時力矩馬達的銜鐵就是擋板）輸出位移或角位移，改變擋板和噴嘴之間的距離，使噴嘴噴出的油液流阻產生變化，進而控制輸小參數。

       RZGO-AES-PS-033/315比例減壓閥-特價ATOS阿托斯特點：ATOS比例控制閥是一種按輸入的電信號連續、按比例地控制液壓系統的流量、壓力和方向的控制閥，其輸出的流量和壓力可以不受負載變化的影響。比例閥與普通液壓元件相比，有如下特點：

      （1）電信號便于傳遞，能簡單地實現遠距離控制。

      （2）能連續、按比例地控制液壓系統的壓力和流量，實現對執行機構的位置、速度、力量的控制，并能減少壓力變換時的沖擊。

      （3）減少了元件數量，簡化了油路。同時電液比例閥的使用條件和保養與一般液壓元件相同，比伺服閥的抗污染性能強，工作可靠。
