Abrasive media? Life problems with your current valves?

RuB has the solution! Thanks to its long experience in industrial applications, RuB offers a variety of configurations specifically designed to solve critical situations. Brass is notably a “soft” alloy with high copper content having features that make it ideal for plumbing and sanitary installations. When it comes to industrial applications, however, you may need the tough chemistry of stainless steel.

And here we are: RuB combines the properties of a brass body with strength of stainless steel ball and stem. Ideal for abrasive media and other severe applications.
