Problem in Metal seated jacketed Butterfly valve

Problem in Metal seated jacketed Butterfly valve

(OP)
We  are having a Metal seated jacketed Butterfly valve  for vacuum service in our Plant fromthe year 2001. Now During Physical inspection of the Valve we are finding Metal
rubbing  in  the  Disc  &  Valve  Seat. The valve is also in
passing  condition. What could be the problem?

Thanks & Regards
