DN = Nominal size
Δp
max
= max. permissible differential pressure across the valve’s control path, valid for the entire
actuating range of the motorized valve
Δp
S
= max. permissible differential pressure (close off pressure) at which the motorized valve will
close securely against the pressure (used as throughport valve)
k
VS
= nominal flow rate of cold water (5 to 30 °C) through the fully opened valve (H

Technical and mechanical design
For a detailed description of operation, refer to data sheet CA1N4028E.
Contr
ol operation The control signal is convert
ed in the terminal housing into a phase cut signal which
generates a magnetic field in the coil. This causes the armature to change its position
in accordance with the interacting forces (magnetic field, counterspring, hydraulics
etc.). The armature responds rapidly to any change in signal, transferring the corre-
sponding movement directly to the control disc, enabling fast changes in load to be
corrected quickly and accurately.
The valve position is inductively measured continuously. Any disturbance in the system
is rapidly corrected by the internal positioning controller, which ensures that the control
signal and the valve stroke are exactly proportional, and also provides a feedback sig-
nal indicating the valve position.
