Fluorine-lined Check Valve Material And Manufacturing Process Description

With the rapid development of my country's economy, the importance of the fluorine-lined valve market has become increasingly prominent. Fluorine-lined check valves, a type of valve that uses fluorine-lined materials as the inner lining and is wrapped with metal on the outer layer, are widely popular for their excellent corrosion resistance.
At present, there are many types of Lined Check Valve lining materials used in China, including polytetrafluoroethylene, polyvinylidene fluoride, polytrifluoroethylene, and polyperfluoroethylene. These materials have strong corrosion resistance and can resist the erosion of chemicals such as acids, alkalis, and salts. Therefore, they are very suitable for the manufacture of fluorine-lined check valve linings.
In the process of producing fluorine-lined check valves, polysoluble tetrafluoroethylene materials are usually evenly laid in the cavity of valve components, such as valve seats and valve plates. This method can quickly and efficiently produce high-quality fluorine-lined check valves.
However, this process also has certain limitations, such as bulging and expansion after heating.
In order to overcome these challenges, the manufacturing technology of fluorine-lined check valves is also constantly improving, including loose lining molding, winding molding, and composite molding. The rational use of these advanced manufacturing technologies will bring significant advantages and unexpected benefits to the molding of fluorine-lined check valve products.
