比例閥按功能分為三大類: (1)比例壓力閥。有溢流閥、減壓閥,分別有直動和先導兩種結構;可連續地或按比例地遠程控制其輸出油液壓力; (2)比例換向閥。有直動和先導兩種結構,直動閥有帶位移傳感器和不帶位移傳感器兩類。由于使用了比例電磁鐵,閥芯不僅可以換位,而且換位的行程可以連續地或按比例地變化。因而連通油口間的通流面積也可以連續或按比例地變化。所以比例換向閥不僅能夠控制執行元件的方向,而且能夠控制其速度。因為這個原因比例閥中的比例換向閥應用也zui為普遍; (3)比例流量閥。有比例調速閥和比例溢流流量控制閥,可連續地或按比例地遠程控制其輸出流量。 比例閥的輸入單元是電-機械轉換器,它將輸入的電信號轉換成機械量。轉換器有伺服電機和步進電機、力馬達和力矩馬達、比例電磁鐵等形式。但常用的比例閥大都采用了比例電磁鐵,比例電磁鐵根據電磁原理設計,能使其產生的機械量(力或力矩和位移)與輸入電信號(電流)的。
