Introduction To Materials And Manufacturing Process Of Fluorine-lined Check Valves

In my country's modern industry, the Lined Valve series products play an important role and are widely used in various industries. There are many types of fluorine-lined valves, among which fluorine-lined check valves are the most commonly used. They use fluorine-lined materials as linings and metal wrapped on the outside. They are valves with excellent corrosion resistance.
At present, there are more than ten kinds of lining materials for fluorine-lined check valves used in my country, such as polytetrafluoroethylene, polyvinylidene fluoride, polytrifluoroethylene, and polyperfluoroethylene. These materials have good corrosion resistance. Acids, alkalis, and salts will not cause corrosion to them, so they are suitable for manufacturing lining materials for fluorine-lined check valves.

When manufacturing fluorine-lined check valves, polysoluble tetrafluoroethylene materials are generally spread flat in the mold cavity of the fluorine-lined check valve, such as valve seats and valve plates. The fluorine-lined check valves produced in this way are fast and good. One defect is that they will bulge and expand after heating.
There are many manufacturing processes for fluorine-lined check valves, such as loose lining molding technology, winding molding technology, composite molding technology, etc. The proper use of these technologies will bring unexpected benefits to the molding of fluorine-lined check valve products.
