2 Installation
2.1 Mounting position
Installation depends on the mounting posi-
tion of the valve. However, do not install the
actuator suspended downwards.
Note: Manual override is only possible in
actuators with fail-safe action when the
power supply is connected (see section 4.1).
2.2 Attachment to the valve
Series V2001 (DN 15 to 80),
Type 3260 Valve (DN 65 to 150) and
Type 3214 Valve (DN 65 to 100)
1. Remove protective covers and unscrew
nut (6) from the valve.
2. Retract actuator stem slightly using the
manual override.
Place actuator with yoke onto the valve
and fasten with the nut (6, SW 36) using
a minimum tightening torque of
150 Nm.
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 stem connector nut (8) until a dis-
tance of x = 75 mm (x = 90 mm for
DN 100 and larger) between the top of
the yoke and the top of the stem connec-
tor 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 stem connector 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
override or motor.
