Installation
5.4.2 Type 5824: form-fit
attachment
1. Place the actuator on the yoke and fasten
with the coupling nut (4).
Tightening torque 20 Nm
Place actuator with yoke (15) on the
valve and fasten with the nut (17).
Tightening torque 150 Nm
A spacer (see Fig. 5-3) is required to mount
a Type 3323 Three-way Valve (DN 65 to
80).
2. Pull plug stem until it reaches the actua-
tor stem or extend actuator stem using
the handwheel (2).
3. Position the clamps of the stem connector
(16) included in the accessories on the
ends of the actuator stem and plug stem
and screw tight.
5.4.3 Type 5825: force-
locking attachment
"Actuator stem extends" fail-safe action
The actuator stem must be retracted before
the actuator can be mounted onto the valve.
The stem can be retracted either mechanical-
ly or electrically. Both methods are described
below.
Note
Retracting the actuator stem mechanically
1. Unfasten the front housing cover and
place a 4 mm Allen key on the red actu -
ating shaft.
2. Retract the actuator stem: turn Allen key
counterclockwise and only as far as the
top end position which is at the point
where the torque switch is activated (see
Fig. 5-4).
Risk of damage to the actuator by moving
the actuator stem too far.
Î
Move the actuator stem only as far as the
top end position.
3. Hold Allen key in place and fasten valve
and actuator together using the coupling
nut.
Tightening torque 20 Nm
Remove Allen key and carefully replace
the front housing cover.
Retracting the actuator stem electrically
1. Remove the front housing cover.
2. Perform electrical wiring as described in
section 5.6 and carefully replace the
front housing cover.
3. Retract actuator stem:
− Apply the supply voltage and retract the
actuator stem electrically until it reaches
the end position (voltage applied to eL
and N or using controller).
