Four Major Technical Points For Degreasing And Cleaning Of 304 Material Sanitary Quick-install Butterfly Valve
Sanitary Butterfly Valve Introduction to degreasing and cleaning methods
The parts of sanitary valves must go through the following processes before assembly:
1. All parts of sanitary butterfly valves need to be polished, and there should be no processing burrs on the surface;
2. All parts of the sanitary butterfly valve body are degreased;
3. After the degreasing of the sanitary butterfly valve, pickling and passivation are carried out, and the cleaning agent does not contain phosphorus; after pickling and passivation, the sanitary butterfly valve is rinsed with pure water, and there should be no residual agent. This step is omitted for carbon steel parts; wipe each part with non-woven cloth, and there should be no lint on the surface of the parts, or blow dry with clean nitrogen;
4. Wipe each part of the sanitary quick-install butterfly valve with non-woven cloth or precision filter paper dipped in analytical pure alcohol until there is no dirty color.
