not exceed that of the control valve (qmmax.).
With the qmnom curve, the differential pressure of the
installation corresponds to the set nominal value.
The qmnom –10 % curve shows the values with a
P-deviation of –10 %. The performance data apply to the
condition ΔP0 ≥ 2 x ΔP. The ensure sufficient valve
authority of the differential pressure control valve, ΔP0
should be ≥ 1,5 x ΔP.
Note: A function of the differential pressure control valve
is also given below this value.
The desired differential pressure ΔP is set as nominal
value on the HydroControl D handwheel.
The total pressure loss of the system section ΔP0 is the
sum of ΔP, ΔPV and, if applicable, the pressure loss of the
partner valve.
