For most mechanical equipment components, the surface finish will greatly affect their performance, and some even directly affect their use. The valve body of the one-piece ball valve is spherical, and the spherical appearance makes it have a certain unloading foundation. If the surface finish is high enough, the surface is difficult to be eroded and polluted.
There are many reasons that affect the surface finish of the one-piece ball valve, which can be divided into those produced in the manufacturing process and those produced in the use process. The causes of the surface finish during the manufacturing process include tool marks from cutting during machining, deformation of the metal material during plasticity, and friction between the casting tool and the surface of the one-piece ball valve. In the process of use, there are more factors affecting the surface finish of the one-piece ball valve, including media, components, environment and even human factors.
In general, when the one-piece ball valve leaves the factory, the manufacturer needs to try to ensure its surface finish, because this is also an important factor affecting the user's desire to buy.
