How to solve the damage of forged steel ball valve?

No matter what the valve, the sealing surface is the most likely to be damaged, will appear in the process of switching plug injury, collision, squeeze and other problems. Forged steel ball valve is easy to make the atoms of the two sealing surfaces permeate each other under the action of high pressure, resulting in adhesion phenomenon; If you move the two covers, there will be adhesions and tearing, especially in the case of the higher the surface roughness of the sealing surface, the more likely to happen. If forged steel ball valve in the closing process of collision or squeeze injury, resulting in local wear or indentation of the sealing surface.

Medium in the activity of the sealing surface is easy to produce wear, washing, cavitation consequences, known as "medium erosion". This situation often causes local damage, so the sealing surface quality must be processed well, in the alternating action of medium erosion and chemical erosion, this is the sealing surface will be strongly eroded. Sealing surface in addition to natural damage, there are man-made damage, man-made damage reasons are: poor design, manufacturing is not fine, improper material selection, installation is incorrect, improper use and maintenance is not enough and so on many factors caused; So we must avoid these situations to make the ball valve in use without any problems, but also to ensure the life of the ball valve.
