Q41F-16P stainless steel ball valve
Product Name:
Q41F-16P stainless steel ball valve
Description:

不銹鋼法蘭球閥 Q41F

不銹鋼法蘭球閥是一種重要的閥類,在石油化工、長輸管線等領域有廣泛應用。球閥的關閉件是一個帶孔的球體(或部分球),球體隨閥桿轉動,實現閥門的開啟或關閉。
  在各種閥門中,球閥的流動阻力最小,全徑球閥打開時,球體通道、閥體通道和連接管徑相等并成一直徑,介質幾乎可以毫無損失的流過。
  球閥旋轉90°即可全關全開,啟閉迅速。與相同規格的閘閥、截止閥比較、球閥體積小、重量輕,便于管道安裝。
