We all know that strong corrosion resistance is one of the important features of sanitary valves. Today we will talk about the three major anti-corrosion methods for sanitary valves. Surface Coating The surface coating is the most widely used method of corrosion protection. It is an indispensable anti-corrosion material and identification mark for sanitary valves. The coating used for valves is usually made of synthetic resin, rubber slurry, vegetable oil and solvent. They are applied to the valve surface to insulate the medium and the atmosphere for corrosion protection. The above coatings are mainly used in less corrosive water, salt water, sea water or the atmosphere. Corrosion inhibitor Corrosion inhibitors…
