They may mean methonized which is a surface treatment for steel to prevent corrosion, especially in seawater. I have sometimes specified it for seawater cooled S&T ammonia refrigeration condensers. Not sure how well it would last in a valve body though.

What is a Metallized valve. A piping spec refers to this expression. What is it referring to. It is not a metal seated valve.
