Product features

The pneumatic fluorine lined ball valve (anti-corrosion ball valve) has super strong corrosion resistance. The valve core adopts fluoroplastic as lining and soft sealing valve seat. It is especially suitable for various strong corrosive media and pipelines with strong acid and alkali to switch off or adjust. Q641f46 pneumatic ball valve is made of PTFE sealing ring, which has reliable sealing performance and zero leakage, which is one of the best choices in anti-corrosion valve. The pneumatic fluorine lined ball valve is only suitable for the working condition of pressure less than 2.5MPa, the medium temperature should not exceed 180 ℃, and it is not suitable for high vacuum environment.
Structure 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 collar. The valve collar and the inside of the valve body are all made of fluoroplastic. The shell is made of investment casting with high strength and bright appearance. The part contacting with liquid is all fluoroplastic. It is a ball valve specially designed to control the opening and closing of various strong corrosive media. It has light switch and small volume It has the advantages of reliable sealing, simple structure, convenient maintenance and wide application range.

Advantages of pneumatic fluorine lined ball valve:

1. It is sealed with fluoroplastic, which has high chemical stability and can be applied to any strong corrosive chemical medium;
2. With full bore and floating ball structure, the valve can be closed without leakage in the whole pressure range, which is more convenient for ball cleaning and pipeline maintenance of pipeline system;
3. The ball of the opening and closing part and the valve rod are cast (forged) as a whole, which eliminates the possibility of the valve rod impacting the pressure bearing parts due to the pressure change, and fundamentally ensures the use safety in the project;
4. The structure is compact and reasonable, and the inner cavity space of the valve body is the smallest, which reduces the medium retention. In addition, the special molding technology makes the sealing surface have good density, and the herringbone ring PTFE packing combination makes the valve achieve zero leakage.

Installation guide for pneumatic fluorine lined ball valve:
 
1. Preparation before installation:
(1) The pipeline before and after the pneumatic fluorine lined ball valve has been prepared. The front and rear pipes should be coaxial and the sealing surfaces of the two flanges should be parallel. Otherwise, the pipeline with fluorine liner must be able to bear the weight of the pipeline.
(2) Clean the pipeline before and after the fluorine lined valve, and remove the oil, welding slag and other impurities in the pipeline.
(3) Check the mark of the pneumatic fluorine lined ball valve of the pipeline, and make sure that the pneumatic ball valve of the pipeline is in good condition. Fully open and close the valve for several times to confirm its normal operation.
(4) Remove the protective parts on the connecting flanges at both ends of the pneumatic fluorine lined ball valve.
(5) Check the valve hole, remove the possible dirt, and then clean the valve hole. Even if there are only tiny particles between the valve seat and the ball, the sealing surface of the valve seat may be damaged.
2. Installation:
(1) Install the valve into the line. Any end of the valve can be installed on the upstream end. The fluorine lined ball valve driven by handle can be installed at any position on the pipeline. However, the pneumatic fluorine lined ball valve with gear box or pneumatic actuator shall be installed vertically, that is, it shall be installed on the horizontal pipeline with the driving device above the pipeline.
(2) Sealing gasket shall be installed between valve flange and pipeline flange according to pipeline design requirements.
(3) The bolts on the flange shall be tightened symmetrically, successively and evenly.
(4) Connect the pneumatic pipeline (when using pneumatic actuator).
3. Inspection after installation:
(1) Operate the pneumatic fluorine lined ball valve of opening and closing pipeline of the driver for several times, which shall be flexible and free of stagnation, so as to confirm its normal operation.
(2) According to the pipeline design requirements, the sealing performance of the flange joint surface between the pipeline and the pipeline pneumatic ball valve is checked.
