Î SeeFig.5-4.
The V2001 mounting kit (see Annex) is re-
quired for mounting the actuator on Series
V2001 (DN65 to 100).
1. Remove protective covers.
2. Actuator without fail-safe action and
with fail-safe action "actuator stem re-
tracts":
Retract the actuator stem using the manu-
al override (see the 'Operation' section).
Actuator with fail-safe action "actuator
stem extends":
Apply the supply voltage. Retract the ac-
tuator stem using the manual override
(see the 'Operation' section).
3. Place the actuator with yoke onto the
valve and fasten using the screws (11).
A spacer (see Fig.5-4) is required to mount
a Type3323 Three-way Valve (DN65 to
80).
4. Switch off the supply voltage.
Î The actuator stem extends.
5. Extend the actuator stem until the actua-
tor stem (3) rests on the plug stem (5).
6. Position the two stem connector parts
(seeFig.5-5)fromtheV2001mounting
kit and fasten tight.
