BURKERT寶德兩位三通導閥/BURKERT6014型導閥原理
BURKERT寶德兩位三通導閥采用濕式交流或直流電磁鐵。該閥是通過電磁鐵控制閥芯的不同工作位置。當電磁鐵斷電時，閥芯靠彈簧壓力保持在中間或終端位（脈沖式閥除外）。電磁鐵通電，閥芯被推到工作位置上，斷電后又恢復到初始狀態(tài)。這時用手推動故障檢查按鈕可使閥芯移動。由于濕式電磁鐵內部與回油腔相通，這樣銜鐵油里移動，可以減少磨損、緩沖，并且提高了散熱，提高了使用壽命。交流電磁鐵具有動作時間短，電氣控制線路簡單，不需特殊的觸頭保護等特點。直流電磁鐵是切換特性軟，動作頻率高，對過載或低電壓反應不敏感，工作可靠。
BURKERT寶德兩位三通導閥工作時，是利用彈簧的壓力來調節(jié)、控制液壓油的壓力大小。從圖3-50中可以看到：當液壓油的壓力小于工作需要壓力時，閥芯被彈簧壓在液壓油的流入口，當液壓油的壓力超過其工作允許壓力即大于彈簧壓力時，閥芯被液壓油頂起，液壓油流入，從圖示方向右側口流出，回油箱。液壓油的壓力越大，閥芯被液壓油頂起得越髙，液壓油經溢流閥流回油箱的流量越大o如過液壓油的壓力小于或等于彈簧壓力，則閥芯落下，封住液壓油進口。由于油泵輸出的液壓油壓力固定，而工作油缸用液壓油的壓力總要比油泵輸出液壓油壓力小，所以正常工作時總會有些液壓油從溢流閥處流回油箱，以保持液壓油缸的工作壓力平衡、正常工作。
