Technical Data - Samson 46-7 Mounting And Operating Instruction

3.1 Technical data

Process medium and scope of application
Flow rate and differential pressure control
with pressure control in district heating sup-
ply networks and industrial plants · Valves
DN 15, 25 and 40 · Pressure rating PN 16
and 25 · Suitable for liquids up to 150 °C
The valve closes when the flow rate, differen-
tial pressure or pressure rises.
Regulator for installation in the low-pressure
pipe, e.g. plant return flow pipe of a district
heating substation.
Min. differential pressure Δp
The minimum required differential pressure
Δp across the valve is calculated as fol-
min
lows:
Δp = Δp
