概述 蝶閥是指關閉件（閥瓣或蝶板）為圓盤，圍繞閥軸旋轉來達到開啟與關閉的一種閥，在管道上主要起切斷和節流作用，當介質要求好的材質時，比如油品及弱腐蝕性流體，需要采用進口不銹鋼蝶閥，它是采用不銹鋼304、316作為閥體材質，采用不銹鋼或者四氟密封的蝶閥，被廣泛用于介質溫度≤425℃的治金 、電力、石油化工、以及給排水和市政建設等工業管道上，作調節流量和載斷流體使用。 Butterfly valve is closed parts （disc or disc） disc rotating around the valve shaft to open and close a valve in the pipe from the main cut off and throttling effect when the media requires good material, such assoil and weak corrosive fluid, imported stainless steel butterfly valve, it is the use of stainless steel 304,316 as the body material, the use of stainless steel or PTFE sealing butterfly valves are widely used in medium temperature ≤ 425 ℃ metallurgy, electric power, petrochemicals, as well as water supply and drainage and municipal construction and other industrial pipe for regulating traffic and carrier off fluid 閥座與碟板密封面均采用不同硬度和不銹鋼制作，具有良好的耐腐蝕性，使用壽命長，本閥雙向密封功能，產品符合國家GBT13927-92閥門壓力試驗標準。
