Fluoroplastic lined valve material and manufacturing process

Large-diameter lined valves can be welded by steel plates, and the welding points meet the requirements of GB/T150 standard. The internal shape of the fluoroplastic lined valve should be as simple as possible, which is convenient for the production of the lining and the mold. The lining surface of the shell should be flat, and all the corners should be arc transitions, and the arc radius R≥2mm. These have specific content and illustrations in the standard, and are also summarized by the company in the production practice of lining valves. Material selection: General valves only consider whether the shell material meets the requirements of the standard, while the fluoroplastic lined valve also considers whether the lining material meets the relevant standards, so the shell material and lining material are listed separately in the technical conditions. standard provisions.
