Burkert 6518先導閥兩位三通
6518是一種兩位三通先導閥,而6519通常是和它組成一個結構系列。先導閥的工作原理就是在通電時,電磁力把先導孔打開,上腔室壓力迅速下降,在關 閉件周圍形成上低下高的壓差,流體壓力推動關閉件向上移動,閥門打開;The electric magnetic force opens the lead hole, the pressure of the upper chamber is rapidly decreased, and the pressure difference of the upper chamber is formed around the closed part. The fluid pressure pushes the closing part upward and the valve opens.
