Neles C oating materials for metal-seated ball valves

Metal seated ball valves achieve sealing by metal to metal contact between the ball and seat. When "soft" metals of similar hardness slide against each other under even moder-ate pressure, galling occurs. Microscopic protrusions on the seating surfaces catch on each other, resulting in surface friction, heat buildup and plastic de-formation.
