Χp
max
= max. permissible differential pressure across the valve’s control path, valid for the entire
actuating range of the motorized valve
Χp
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

) at a
differential pressure of 100 kPa (1 bar)
