Rotometering Valve

The Rotometring valve is a fine dosing valve. It consists of two coaxial dosing parts (independently actuated), which determine flow of the product and its dosage.

The  Rotometering  valve  is  particularly  suitable  for  process  where product does not flow easily: the auger screw movement allows the product to be physically transferred, favoring dosing.
