2 Installation
2.1 Mounting position
Installation depends on the mounting posi-
tion of the valve. However, do not install the
actuator suspended downwards.
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 min. tightening torque of
150 Nm. If necessary, retract actuator
stem slightly beforehand using the ma-
nual override.
3. When the plug stem (5) fits closely onto
the actuator stem (3), attach both coup-
ling 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
coupling 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 150)
1. Place actuator onto the valve and se-
cure with the ring nut (7). If necessary,
retract actuator stem slightly before-
hand using the manual override.
2. When the plug stem fits closely onto the
actuator stem (3), attach both coupling
clamps (4) and screw tight.
3. Move actuator stem (3) to the end posi-
tion (valve closed) using the manual
override or motor.
4. Align travel indicator scale (10) to the
middle of the stem connector (4) and
screw tight.
