tion of the valve. However, do not install the
actuator suspended downwards.
Note!
Manual override is only possible in actua
-
tors with fail-safe action when the power
supply is connected (see section 4.1).
2.2 Attachment to the valve
Series V 2001 (DN 15 to 80),
Type 3260 Valves (DN 65 to 150) and
Type 3214 Valves (DN 65 to 100)
1. Remove protective covers and unscrew
nut (6) from the control valve.
2. Place actuator with yoke onto the valve
and fasten with the nut (6, SW 36) using
a minimum tightening torque of
150 Nm. If necessary, retract actuator
stem slightly beforehand using the man
-
ual override.
3. When the plug stem (5) fits closely onto
the actuator stem (3), attach both stem
connector clamps (4) and fasten with
screws.
Series 240
1. Push plug stem down to close the valve.
2. Turn coupling nut (8) until a distance of
x = 75 mm (x = 90 mm for DN 100 and
larger) between the top of the yoke and
the top of the coupling nut (8) is
reached. Secure position with lock nut
(9).
3. Place actuator onto valve bonnet (2.3)
and fasten with ring nut (7).
If necessary, retract actuator stem
slightly beforehand using the manual
override.
4. When the coupling nut (8) fits closely
onto the actuator stem, attach both stem
connector clamps (4) and screw tight.
5. Move actuator stem (3) to the end posi
-
tion (valve closed) using the manual
override or motor.
6. Align travel indicator scale (10) to the
middle of the stem connector (4) and
screw tight.
Type 3214 (DN 125 to 250)
1. Place actuator onto the valve and secure
with the ring nut (7). If necessary, retract
actuator stem slightly beforehand using
the manual override.
2. When the plug stem fits closely onto the
actuator stem (3), attach both stem
connector clamps (4) and screw tight.
3. Move actuator stem (3) to the end posi
-
tion (valve closed) using the manual
