Installation
5.3 Aligning the travel indica-
tion scale
The travel indication scale has two opposed
scales. Which scale is to be used depends
on the valve version. In the delivered state,
the scale alignment applies to globe valves
and three-way diverting valves. The align-
ment needs to be changed when a three-
way mixing valve is used.
Driving pin in position 0,
location of scale with globe or three-way
diverting valves (delivered state)
Fig. 5-2: Travel indication scale
Globe and three-way diverting valves:
the driving pin is in position 0 (delivered
state).
Three-way mixing valve:
change the alignment of the scale.
Î Carefully open the front cover.
Tip
We recommend screwing the bottom screws
of the open housing front cover into the top
holes of the housing.

Hole for driving pin
with three-way mixing
valve
Î Remove scale, turn it and replace it so
that the pin is positioned over the appro-
priate hole (6, 12 or 15) corresponding
to the rated travel (6, 1 or 15 mm travel).
Î Close front cover.
5.4 Mounting the actuator
The actuator is mounted either directly onto
the valve or using a yoke depending on the
valve version used (see Fig. 5-3).
NOTICE
!
Risk of actuator damage due to excessively
high tightening torques.
Î Observe the tightening torque.
NOTICE
!
Risk of damage to the actuator by turning it
too far.
Î Only turn the handwheel far enough to
move the actuator to the end positions at
the maximum.
