What damage can sanitary valves cause in use

In the process of use, if the sealing surface is damaged, it will directly affect its good performance, then what are the common injuries of the sanitary valve surface?

1. Repeated cyclic loading and unloading will cause fatigue cracks on the surface or the lower surface, resulting in debris and pits on the surface, leading to surface damage.

2. rough hard surface sliding on the soft surface wear, hard material pressure on the soft surface of the material, sliding on the soft surface wear, in the contact surface will draw a tiny groove, the groove off the material in the form of debris or loose particles are pushed away from the surface of the object.

3. Material damage is caused by sharp particles colliding with the surface of an object. It is similar to abrasive wear, but the surface is very rough.

4. When the metal surface is corroded, a layer of oxide is produced. This layer of oxide usually covers the corroded area, which slows down further corrosion of the metal.However, if sliding occurs, it removes the oxides from the surface, leaving the exposed metal exposed to further corrosion.

5. Scratch is the material damage caused by friction in the process of the relative movement of the sealing surface.

These factors may lead to health valve surface damage, so in the processing process, to pay more attention to
