Understanding Metal-Seated Ball Valve Coating Materials ...
Between the seat and the ball, there is metal to metal contact. This is how sealing is achieved by a metal seated ball valve. Unfortunately, galling occurs when even moderate pressure is present as similar hardness slide against each other. Eventually, the valve will seize up as the damage worsens. That is, if no coatings are applied.
