概述Outline：
Q641F46氣動襯氟球閥是采用氟塑料作為內襯，并配之以新型的帶桿球體結構，再加上其*的彈性唇式密封座結構，使其具有普通球閥的各項優點，能在大壓差和較大的溫差變化范圍內具有高密封性能和低操作扭矩。可作開關或調節之用，本產品適用于各種工業管道中液體和氣體的輸送（包括蒸氣），在各種酸、堿、鹽類等強腐蝕性介質中均能很好地工作。全通徑閥門提供zui大的流量，并可用于掃線清洗或隔離輸送的管道。
產品廣泛適用于各種不同類型工業管道中液體和氣體（包括蒸氣）的輸送，特別是具有嚴重腐蝕性介質的使用場合，如：硫酸、氫氟酸、磷酸、氯氣、強堿、王水等具有強腐蝕性的介質。

Q641F46 pneumatic fluorine fluorine plastic ball is used as a liner and combined with a new sphere with the pole structure, coupled with its unique elastic lip seal seat structure, it has the advantages of an ordinary ball valve can in large changes in pressure and temperature within a larger sealed with high performance and low operating torque. Can be used for switching or adjustment purposes, the product is suitable for a variety of industrial pipeline transport of liquids and gases （including steam）, in a variety of acids, alkalis, salts and other corrosive media can work very well. Full bore valves to provide maximum flow, can be used to sweep the line clean or quarantine transmission pipeline.
The products are widely used in various types of industrial liquid and gas pipeline （including steam） delivery, especially those with severe corrosive media use situation, such as: sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, alkali, aqua regia, etc. strong corrosive media.
