優(yōu)勢提供美國PARKER兩位三通換向閥D41VW001C1NJWTI6N
（2）六通閥有兩組密封組件。每組密封組件（圖2）由閥瓣、密封圈、調整塊、調節(jié)螺釘、夾板和螺栓組成。閥瓣為碳鋼板焊件,設有加強筋,即增加閥瓣強度又起導向作用,保證每組閥瓣間的同軸度。閥瓣上鑲嵌聚氨脂橡膠圈,該材料具有耐油、耐磨損、性能穩(wěn)定、密封良好和使用壽命長的特點。在凸輪的作用下,密封圈的球面與閥體密封面相接觸產(chǎn)生擠壓彈性變形,達到密封效果。調整塊和調節(jié)螺釘在兩組密封組件不能同步到位時可起調整作用,確保各通道密封性能同步到位。

（3）閥桿與閥體隔板和上閥蓋間的軸向密封采用O形圈。
（4）閥體隔板及上閥蓋軸孔部位鑲有銅套,可減小與O形圈間的摩擦力矩,密封組件開啟與關閉靈活,操作力矩小。
（5）上閥蓋設有指示牌及限位螺釘,閥桿上安裝指針,明確指示各通道的接通狀況,易于操作。美國PARKER電控4/3或4/2通換向閥D41VW系列
