PARKER比例換向閥 美國派克parker比例閥
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。
Parker派克直動式比例換向閥D*FL系列
DSEEBD517P20FLAF
DSAEBD1017E40FLAF
DSAEBD1017E50FLAF
DSAEB1007P07FLAF
DSAEB1017E40FLAF
公稱尺寸為CETOP3和CETOP5的D*FL系列的閥是一種用于流量控制的數字式比例閥。這種用微處理器控制的4-通閥可以通過配電信號來調出不同的給定速度。在閥上可以對加速度、減速度和速度進行調節。典型的快速/低速行程特性可以不用其它的模塊就可實現。
Parker派克直動式比例換向閥WL*NG10系列
公稱尺寸為CETOP5的WLL系列直動式比例閥被用于控制流量。該閥（D*FW）采用歐卡規格的VDR350/355數字式功率放大器或采用PWD-400/PCD400功率放大器模塊進行電控。典型的應用是：流量控制和可實現流量調節，快速/低速行程特性控制和液壓傳動裝置的定位。
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
