Fig. 10: Adjusting ring for presetting the volume flow rate
1. Turn the blue plastic cap 580.1 anti-clockwise to remove it from the bonnet.
2. Loosen the locking device (locknut) by approx. one full turn.
3. Turn the adjusting ring until the required value is set. Do not exceed the
operating range (1-5). For the relationship between the volume flow rate and
the values shown on the adjusting ring refer to (
ð Table 12) .
4. Tighten the locking device to prevent the preset value being changed
inadvertently.
5. Fit the blue plastic cap 580.1 again to prevent contamination.
6. Turn the blue plastic cap 580.1 clockwise until it lightly touches the stem end.
CAUTION
Unintentional closing of valve when setting the volume flow rate
No throughflow!
▷ When fitting the blue plastic cap only turn it until it lightly touches the stem
end.
▷ Do not tighten the blue plastic cap up to the stop.

Markings are provided on the manual gearbox to simplify presetting the required
volume flow rate. The maximum volume flow rate Qmax per nominal size in in m³/h
is indicated in a table (Q) and as a percentage on the rotating disc (S).
1. Check the locking device. Loosing it, if necessary, by turning the knurled thumb
screw (F).
2. Set the required volume flow rate by turning the handwheel on the manual
gearbox. Turn the indication until the arrow (P) points at the required
percentage on the disc (S). For presettings in percent refer to (
ð Table 13) .
3. Activate the locking device by turning the knurled thumb screw (F).
