Specializing In The Production Of 3 Piece Threaded Ball Valve Series

With the rapid development of modern industry, 3 Piece Threaded Ball Valve and their various ball valves and piping accessories have been rapidly adopted and promoted in various fields such as petroleum, printing and dyeing, and chemical engineering. They have demonstrated strong vitality and, as a preferred project in engineering projects, have attracted significant attention and favor from various engineering design and construction companies, representing a product with great market potential.

Fluorine-lined valves, also known as fluoroplastic-lined corrosion-resistant valves, are manufactured by molding (or inlaying) polytetrafluoroethylene resin (or processed profiles) onto the inner wall of steel or iron valve pressure-bearing components (the same method is also applicable to the lining of various pressure vessels and piping accessories) or the outer surface of valve trim. This unique resistance to highly corrosive media is utilized to manufacture various valves and pressure vessels.

Fluorine-lined valves are lined with a lining process that covers all areas of the valve body accessible to the media. Lining materials typically include fluoroplastics such as FEP (F46) and PCTFE (F3). These valves are suitable for use in pipelines handling various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, aqua regia, various organic acids, strong acids, strong oxidizers, and other corrosive media. However, they are subject to significant temperature limitations (applicable only to media between -50°C and 150°C).

Fluorine-lined valves include gate valves, ball valves, butterfly valves, check valves, globe valves, plug valves, diaphragm valves, filters, discharge valves, regulating valves, pipe fittings, and sight glasses and cups. Manufacturing technology includes the formulation and production process of the adhesive. The adhesive ensures a strong affinity between the lining adhesive and the pipe wall, resulting in excellent corrosion and scaling resistance and a long service life. It can also make the valve have both the strength of metal and the corrosion resistance.
