How to calculate the running time of a motorized control valve
The running time of the motorized control valve is calculated using the following methods:
Seated valves
Running time = Valve stroke (mm) x actuator speed (sec. / mm)
Example: 5.0 mm x 15 sec. / mm = 75 sec.
Rotating valves
Running time = Turning degrees x actuator speed (sec. / degr.)
Example: 90 degr. x 2 sec. / degr. = 180 sec.
Nz (neutral zone) 6187
Setting range Factory setting
1 ... 9 K 3 K
Set the acceptable ow temperature deviation.
Set the neutral zone to a high value if you can accept a high variation in ow
temperature. When the actual ow temperature is within the neutral zone, the controller
does not activate the motorized control valve.
The neutral zone is symmetrical around the desired ow temperature value, i.e. half the
value is above and half the value is below this temperature.
