First, pneumatic line fluorine ball valve product overview

　　Q641F46 pneumatic lined fluorine ball valve is designed for the automatic opening and closing control of various corrosive medium pipelines, widely used in petroleum, chemical, dyeing, acid and alkali manufacturing industries, is currently one of the most ideal choice of anticorrosive valve equipment. Pneumatic lined four-fluorine ball valve is fluorine plastic lining, the shell is investment precision casting, high strength, smooth appearance, and the liquid contact part of all fluorine plastic, so pneumatic lined fluorine ball valve can be used in the range of -20℃ ~ 180℃ for a long time in any concentration of corrosive pipeline, pipeline work.

Second, pneumatic lined fluorine ball valve structure principle and advantages

　　

The working principle of pneumatic lined fluorine ball valve is to rotate the valve love to make the valve unblocked or blocked, the valve love and valve body inside all made of fluorine plastic, the shell is made of investment precision casting, high strength, smooth appearance, and liquid contact part of all fluorine plastic, is specially designed to control the opening and closing of various corrosive media and the ball valve, it has a light switch, small size, Reliable sealing, simple structure, convenient maintenance, wide range of use and so on.


Pneumatic ball valve lined with fluorine advantages:


1. Fluorine plastic seal, with high chemical stability, can be applied to any strong corrosive chemical media;


2. Adopt full diameter, floating ball structure, the valve can be closed in the whole pressure range without leakage, more convenient for the pipeline system through the ball line sweeping and pipeline maintenance;


3. The ball of opening and closing parts is integrated with the valve stem casting (forging), which eliminates the possibility of the valve stem impacting the bearing parts due to pressure changes, and fundamentally ensures the safety of use in the project;


4. The structure is compact and reasonable, the body cavity space is minimum, reducing the medium retention, in addition, the special molding process, the sealing surface density is good, and the herringbone PTFE packing combination, so that the valve to zero leakage.
