Is the product of the solenoid valve easy to corrode? You need to master these methods

There are many factors affecting the service life of the solenoid valve, and the corrosion of the solenoid valve is one of the most important factors. Prolonging the service life of the solenoid valve and improving the safety of the project, the corrosion protection of the solenoid valve is an important consideration. How can the solenoid valve be protected effectively and what should be noticed in the selection and purchase of the solenoid valve? You need to know the following methods.
Selection of corrosion resistant materials based on medium type
In practical production applications, there are various kinds of media that the solenoid valves are facing. Even in the same medium, the corrosion rate of materials is different under different pressure, temperature and concentration.  For example, aluminum is highly corrosive in concentrated nitric acid above 80%, but corrosion is not serious in medium and low concentrations of nitric acid. The corrosion of carbon steel is the most serious in the sulfuric acid with a concentration of 50%. When the concentration is above 90%, the corrosion decreases sharply. Therefore, when purchasing solenoid valve products, we can analyze the types of media and the corrosion degree of materials with different concentration media, and consult with manufacturers directly.
Selection of corrosion resistant solenoid valves
Corrosion resistant solenoid valves are specially designed for corrosive media. Many corrosion-resistant solenoid valves use non-metallic materials as the interface between electromagnetic valve and dielectric. Materials like natural rubber and polyvinyl chloride four have good corrosion resistance. As long as the pressure and temperature of the project conform to the characteristics of materials, they also play a role in saving precious metals. For example, Shanghai giant Liang as a domestic high-end electromagnetic valve manufacturers, its products are not only the metal material corrosion resistance of electromagnetic valve equipment, as well as the use of non contact materials processing medium and cavity wall, customers can purchase according to the actual conditions of their own, can also be customized to a giant benign.
Surface treatment of solenoid valve
The surface treatment of the solenoid valve can be divided into thermal spraying and spray paint. Thermal spraying is one of the technologies for adding protective coating to the surface of the equipment. Thermal spraying is the use of high energy density heat source, such as gas combustion flame, arc, plasma arc, electric heating, gas explosion and so on, heating and melting metal or non-metallic materials, spray into the pretreated basic surface in the form of atomization, forming spray coating. Thermal spraying can improve the corrosion resistance, wear resistance and high temperature resistance of the surface of the solenoid valve, and prolong the service life of the product.
Spray coating is a common method. Coating is a non-metallic material. It can effectively insulate the medium and atmosphere by coating on the metal surface or inner cavity, so that it can achieve the purpose of anticorrosion.
Control corrosion environment
Controlling corrosion environment is mainly for the working environment of solenoid valve, for example, it can control dust, steam, smoke and toxic gas in environment effectively, and keep the environment clean and dry.
Shanghai Ju Liang is the leading domestic high-end valve manufacturers, the company's products include pneumatic valve, solenoid valve, electric valve, regulating valve, angle seat valve, self operated control valve and a common valve and other types of products, has become the focus of national engineering construction important partners.
