Solenoid valve surface treatment

Solenoid valve surface treatment can be divided into thermal spray and spray paint. Thermal spraying is one of the techniques for adding a protective layer to the surface of a device. Thermal spraying is the use of high energy density heat sources, such as gas combustion flames, arcs, plasma arcs, electric heating, gas explosions, etc., after heating or melting metal or non-metal materials, and spraying them into the pretreated basic surface in the form of atomization to form Spray layer. 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 paint is a more common method. The paint belongs to a non-metallic material and is applied to the metal surface or the inner cavity to effectively isolate the medium and the atmosphere for anti-corrosion purposes.


Control the corrosive environment


Controlling the corrosive environment is mainly for the working environment in which the solenoid valve is located. For example, it can effectively control dust, water vapor, smoke and toxic gases in the environment to keep the environment clean and dry.
