Parker比例換向閥工作原理：電液比例換向閥是閥內比例電磁鐵輸入電壓信號產生相應動作，使工作閥閥芯產生位移，閥口尺寸發生改變并以此完成與輸入電壓成比例壓力、流量輸出元件。閥芯位移也可以以機械、液壓或電形式進行反饋。Parker比例換向閥具有形式種類多樣、容易組成使用電氣及計算機控制各種電液系統、控制精度高、安裝使用靈活以及抗污染能力強等多方面優點，應用領域日益拓寬。
Parker比例換向閥是具有兩種以上流動形式和兩個以上油口的方向控制閥。是實現液壓油流的溝通、切斷和換向，以及壓力卸載和順序動作控制的閥門。
Parker比例換向閥按閥的結構形式：滑閥式、轉閥式、球閥式、錐閥式。
Parker比例換向閥按閥的操縱方式：手動式、機動式、電磁式、液動式、電液動式、氣動式。
Parker比例換向閥按閥的工作位置數和控制的通道數：二位二通閥、二位三通閥、二位四通閥、三位四通閥、三位五通閥等
Parker派克D*6FH系列先導式比例換向閥公稱尺寸為CE*0至CETOP25(派克的廠內標準)的D*6FH系列先導式連續調節的換向閥被用于控制和調節流量。該閥具有集成的電子元件，主級王的閥芯位置可調。與標準的閥相比集成的持續的差動回路可提供更高的流量。典型的應用是：流量控制精確和可實現流量調節，在快速/低速特性下的工作運行帶有閥芯位置監控例如：壓力機控制，動態的位置調節和壓力/流量閉環系統調節。
Parker派克先導式比例換向閥D*1FW/D*1FT系列公稱尺寸為CETOP5和CE*0的D*1FW和D*1FT系列先導式比例換向閥被用于控制流量。該(D*1FW)采用PWD-400功率放大器進行電控或將集成的電子元件插裝在閥上組成一體(D*1FT)。典型的應用是：通過調節斜坡信號可使閥芯柔和換向，以此來減小液壓和機械沖擊，通過電氣方式調節流量/速度可實現機械功能的自動化。
Parker派克先導式比例換向閥D*1FS系列公稱尺寸為CETOP3至CE*0的D*1FS系列先導式比例換向閥被用于控制流量。該閥采用EW系列模擬式功率放大器進行電控或采用VRD350/355數字式功率放大器。主閥芯的位置可調。典型的應用是：流量控制精確和可實現流量調節，在快速/低速特性下的工作運行和柔和加速度以及延遲工作特性的改善。
Parker派克直動式比例換向閥D*FW/D*FT系列公稱尺寸為CETOP3和CETOP5的直動式(D*FW)換向閥系列是一種用于流量控制的比例閥。該閥(D*FW)采用PWD-400/PCD-400功率放大器進行電控或將集成的電子元件插裝在閥上組成一體(D*FT)。典型的應用是：通過調節斜坡信號可使閥芯柔和換向，以此來減小液壓沖擊和機械沖擊，通過電氣方式調節流量/速度可實現機械功能自動化。
