PTFE F4 FEP F46 PFA Butterfly Valve Introduction:

The valve body, valve seat and valve core lining of F46 flanged fluorine-lined butterfly valve are integrated. When the valve is working, only the valve body lining and the plastic-lined butterfly plate are in contact with the medium. The valve can withstand the corrosion of the medium introduced by the lining material. The four-pole sealing structure is equipped with an elastic gasket of temperature-resistant and anti-aging SI rubber on the sealing surface, which completely achieves zero leakage of the medium, has tight sealing performance, and has a long service life. 

Fluorine-lined butterfly valve is suitable for water supply and drainage and gas pipelines such as food, medicine, chemical industry, petroleum, electric power, light textile and paper making, etc. with temperature ≤120℃ and nominal pressure ≤1.6MPa. In various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, strong oxidants and other media.

Quality inspection of fluorine-lined butterfly valve

Different manufacturers also need to do a good job in quality control and testing when manufacturing fluorine-lined butterfly valves. Only by ensuring the quality of the product can it play a better role in the use process. We can take a look at the specific inspection items, and through the specific inspection items, we can better select the valve to ensure that it is more widely used in the market.

Inspection of fluorine-lined pipes

The pipeline is very important in the inspection process. In the process of manufacturing, professional manufacturers not only need to do the unpacking inspection work, but also include professional inspection. For example, the number, model, specification, surface damage, and air pressure test and air tightness test of the product need to be checked. Only through these aspects can we know the specific function and function of the product, and can also ensure better use.

Inspection of fluorine-lined valves

The valve is checked because of concerns that it has quality problems during use or that the thickness does not meet the requirements. The inspection of the fluorine-lined butterfly valve itself involves a lot of content. We hope that in addition to meeting certain specifications and models during use, the appearance of the fluorine-lined butterfly valve also looks very beautiful, and the overall test results also meet the corresponding requirements to ensure that it can be better use.

Combining the above content, we can also find that since the fluorine-lined butterfly valve is widely used in the current market, professional manufacturers should also control the quality in the process of processing and production. It should be ensured that the appearance is beautiful and the performance is good, which also allows the valve to be used more widely in the market.
