INFORMATION!
The operating pressure should be at least double the pressure loss for liquids and five times for
gases. The indicated pressure losses are valid for water and air at maximum flow rate. Other
flow ranges on request. Conversion of other media or operating data is performed using the
calculation method in accordance with VDI /VDE Directive 3513.
