概述Outline：
Q641F46气动衬氟球阀是采用氟塑料作为内衬，并配之以新型的带杆球体结构，再加上其独特的弹性唇式密封座结构，使其具有普通球阀的各项优点，能在大压差和较大的温差变化范围内具有高密封性能和低操作扭矩?？勺骺鼗虻鹘谥茫静肥视糜诟髦止ひ倒艿乐幸禾搴推宓氖渌?包括蒸气)，在各种酸、碱、盐类等强腐蚀性介质中均能很好地工作。全通径阀门提供*大的流量，并可用于扫线清洗或隔离输送的管道。
产品广泛适用于各种不同类型工业管道中液体和气体(包括蒸气)的输送，特别是具有严重腐蚀性介质的使用场合，如：硫酸、氢氟酸、磷酸、氯气、强碱、王水等具有强腐蚀性的介质。

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.
