INFORMATION!
The operating pressure should be at least twice the pressure loss for liquids, and at least 5
times the pressure loss for gases! The specified pressure drops are valid for water and air at
maximum flow rate. Other flow ranges on request. Conversion of other media or operating data
(pressure, temperature, density, viscosity) is performed using the calculation method in
accordance with VDI /VDE Directive 3513.
