1.Valves and external corrosion

① Body (including the variable speed transmission box) inside and outside, first blasting sand blasting, non-toxic epoxy powder electrostatic spraying sought, the thickness of 0  3mm or more. Oversize valves electrostatic spraying toxic epoxy resin having difficulty, we should brush, spray non-toxic epoxy paint similar.

② Internal body and the valve plate all parts calls for a comprehensive anti-corrosion, while immersed in water will not rust, does not arise between the two metal electrochemical corrosion; two aspects of smooth surface to reduce drag through the water.

③ Valve body paint corrosion epoxy or health requirements, should the appropriate authority organs of test reports. Chemical physical properties should meet the relevant requirements.
