What is the working voltage of the pneumatic automatic butterfly valve and the seawater material? The assembly technology of pneumatic butterfly valve requires that the installation materials must be degreased and cleaned before installation to ensure cleanness. According to the processing requirements, some parts need to be polished, and the surface should be free of machining burrs; All parts shall be degreased; Acid cleaning and passivation shall be carried out after degreasing, and the cleaning agent does not contain phosphorus. The assembly technology of pneumatic butterfly valve requires that after pickling and passivation, the valve should be washed with pure water to be clean, and there should be no reagent residue. This step is omitted for carbon steel parts; Wipe the parts one by one with non-woven cloth. Do not leave the appearance of the parts such as wire wool, or use clean nitrogen to dry them; Wipe the parts one by one with non-woven cloth or precision filter paper dipped in analytical pure alcohol until there is no dirty color.
、 Third, understand the after-sales service provided by the butterfly valve supplier. In the field of parts in the automation industry, it is no exaggeration to say that what you buy is after-sales service. Some high-quality manufacturers can provide 5-10 free maintenance services.
