| 1. According to the processing requirements, some flanged ball valve parts need to be polished, and there should be no processing burrs on the surface; 2. All parts of the flanged ball valve are degreased; 3. After the degreasing is completed, pickling and passivation is carried out, and the flange ball valve cleaning agent does not contain phosphorus; 4. Rinse with pure water after pickling and passivation. The flange ball valve must not have any chemical residues, and this step is omitted for carbon steel parts; 5. Wipe the parts with non-woven fabrics one by one, and the parts of the flange ball valve should not be left on the surface of the parts such as wire hair, or dry them with clean nitrogen; 6. Wipe the parts and components one by one with non-woven fabric or precision filter paper dipped in analytical pure alcohol until there is no dirty color. flanged ball valve：https://www. kwvalvescontrol.com/ B53-Forged-Body-Flan ged-Ball-Valves.html | |
