Dimensiones
To select the nominal size Nominal size The nominal size is an alphanumeric designation of size for components in a piping system, used for reference purposes, comprising the letters DN followed by a dimensionless integer that is indirectly related to the physical size of the bore or outside diameter of the connections, expessed in millimeters. (DN), please use the flow capacity chart on the following pages

Diagrama de flujo volumétrico

The volume flow V in m³/h was determined with water according to DIN EN 60534 at a temperature Tn = 20°C and an atmospheric pressure pn = 1,013 bar, kinematic viscosity v = 10-6 m²/s
To avoid electrostatic charge of flammable liquids the maximum flow is limited (refer to TRGS 727, CENELEC-Report CLC/TR 60079-32-1).
