我公司”乾QY儀”擁有多年生產經驗蝶閥的歷史并有部分產品申請獲得了，在不斷吸引外資技術和運用的基礎上獲得了市政和用戶的青睞。

蝶閥是用圓形蝶板作啟閉件并隨閥桿轉動來開啟、關閉和調節流體通道的一種閥門。蝶閥不僅結構簡單、體積小、重量輕、材料耗用省，安裝尺寸小，而且驅動力矩小，操作簡便、迅速，并且還同時具有良好的流量調節功能和關閉密封特性，在大中口徑、中低壓力的使用領域，蝶閥是主導的閥門形式。 結構特點：蝶閥具有結構簡單、體積小、重量輕、材料耗用省，安裝尺寸小，開關迅速、90°往復回轉，驅動力矩小等特點，用于截斷、接通、調節管路中的介質，具有良好的流體控制特性和關閉密封性能。 公稱壓力或壓力級：PN1.0-4.0MPa、ANSI CLASS 150-300LB、JIS10-20K 公稱通徑或口徑：DN40～2000 連接方式：法蘭連接、對夾連接、對焊連接及凸耳對夾連接適用溫度：-196℃～700℃ 驅動方式：手動、蝸輪傳動、氣動、電動、液動、氣液聯動、電液聯動閥體材料：HT200、WCB、ZG1Cr18Ni9Ti、ZG1Cr18Ni12Mo2Ti、CF8(304)、CF3(304L)、CF8M(316)、CF3M(316L)。
