FQ41F46 fluorine discharge valve series is the extension of fluorine valve, designed for on-off control of various strong corrosive medium, the two ends of the valve flange size, one standard flange flange is arranged at one end of the bottom of the reaction kettle and discharge hole matching, very convenient to connect in the reaction kettle. The structure in the form of floating straight through, the connection form of flange, valve shell is made of carbon steel lined with fluorine plastic valve, ball and stem one-piece metal insert manufacturing outsourcing fluorine plastic corrosion process, has good sealing performance, flexible opening and closing, the characteristics of rapid and beautiful appearance, high strength, durable. Is the most widely used in the modern chemical process.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.

放料球阀基本系列为Q41F型，除具有一般球阀所具有的流体阻力小，启闭速度快，结构简单外，还有以下优点： 
       1.采用氟塑料衬里层的球阀，具有极高的化学稳定性，可以适用于任何强腐蚀性化学介质； 
       2.采用全通径、浮动球结构，阀门可在整个压力范围内进行无泄漏关闭，更便于管路系统的通球扫线和管路维护； 
       3.启闭件球体与阀杆铸（锻）为一体，杜绝了由于压力变化引起阀杆冲击承压件内的可能性，从根本上保证了使用中的安全性； 
       4.结构紧凑合理，阀体内腔空间最小，减小了介质滞留，另外，特殊的模压工艺，使密封面致密度良好，加之人字环形PTFE填料组合，使阀门达到零泄漏。
