Product features

The pneumatic fluorine lined ball valve (anti-corrosion ball valve) has super corrosion resistance. The valve core uses fluorine plastic as the lining and soft sealing valve seat. It is especially suitable for various strongly corrosive media and pipelines with strong acid and alkali. It can be used for on-off or adjustment. Q641F46 pneumatic ball valve adopts a sealing ring made of polytetrafluoroethylene, with reliable structural sealing performance and zero leakage at most. It is one of the best choices for anti-corrosion valves. The pneumatic fluorine lined ball valve is only applicable to the working condition with the pressure within 2.5Mpa. The medium temperature should not exceed 180 ℃, and it is not suitable for the high vacuum pumping environment.
Structural principle of pneumatic fluorine lined ball valve:
 
The working principle of the pneumatic fluorine lined ball valve is to make the valve unblocked or blocked by rotating the valve. The valve and the inner side of the valve body are all made of fluoroplastics. The shell is investment casting, with high strength and smooth appearance. The parts in contact with the liquid are all fluoroplastics. It is a ball valve specially designed to control the opening and closing of various strong corrosive media. It has the advantages of light opening and closing, small size, It has the advantages of reliable sealing, simple structure, convenient maintenance, wide range of use, etc.

Advantages of pneumatic fluorine lined ball valve:

1. It is sealed with fluoroplastic, which has extremely high chemical stability and can be applied to any strong corrosive chemical medium;
2. Full bore, floating ball structure is adopted, and the valve can be closed without leakage within the whole pressure range, which is more convenient for ball sweeping and pipeline maintenance of the pipeline system;
3. The ball of the hoist and the valve stem are cast (forged) as a whole, which eliminates the possibility of the valve stem impacting the pressure parts due to pressure changes, and fundamentally ensures the safety of use in the project;
4. The structure is compact and reasonable, and the inner space of the valve body is the smallest, which reduces the retention of media. In addition, the special molding process makes the sealing surface have good density. In addition, the herringbone ring PTFE packing combination makes the valve reach zero leakage.
