FlowAct Actuator
4.2.1 First Installation (figure 17)
The FlowAct actuator is equipped with a casted yoke,
for all assembly and disassemble the entire actuator
including the yoke must be installed or removed.
Remove the locknut (17.1) from the valve bonnet. Place
the actuator and yoke assembly (17.2 ) onto the valve
bonnet. Before connecting the coupling (17.3 ) slip
the locknut over the valve stem (17.4 ) and screw the
locknut onto the bonnet thread. For tightening torques
please refer to chapter 7.3
CAUTION:
Be careful while putting the yoke plate
through the stem. Damage of the stem and/or the
entire trim assembly may occur.
NOTE:
Ensure that the serial sumber of the valve
(engraved at the bonnet) and actuator (Tag plate)
correspond to each other.
4.2.2 Removing for repair or maintenance
We recommend separating the actuator from the valve
during all repair work. However, many maintenance and
adjusting operations can be carried out in an installed
condition.
4.2.2.1 Shut off air supply
4.2.2.2 Disconnect all air tubing from the actuator
4.2.2.3 Remove actuator coupling (figure 18)
NOTE:
If there are accessories such as positioners and/
or limit switches connected to the coupling, please
carefully disconnect the lever or if necessary the entire
accessory. Remove four screws (18.1) from the upper
coupling half.
4.2.2.4 Remove locknut (18.2)
NOTE:
The lower coupling half is still connected to the
stem and can’t be removed from the actuator at this
stage.
4.2.2.5 Carefully raise the actuator assembly vertically around
40 mm. Be aware that most of the FlowAct actuators
are heavy, please use suitable lifting equipment.
4.2.2.6 Remove the lower coupling half (18.3) counter
clockwise from the stem.
NOTE
: Ensure that the plug assembly is not rotated with
the plug seated. This may cause irreparable damage
to the seating faces and/or the bellows seal.
