4.1.3 Install Actuator
(figure 15)
The actuator stem must be fully extended:
Actuators with air-to-open action must be fully vented.
Actuators with air-to close action apply pressure.
Manually depress the plug stem to ensure the plug is
fully seated.
4.1.3.1 Screw coupling insert locknut (15.1) and coupling
insert (15.2) as far as possible onto plug stem (15.3)
4.1.3.2 Place the actuator assembly on the valve engaging the
yoke rod threads in the lower yoke plate (15.4) and
ensuring the actuator faces in the right direction.
4.1.3.3 Unscrew the coupling insert until the lower yoke rods
are raised from the lower yoke plate by around 2 mm.
NOTE:
Ensure that the plug assembly is not rotated with
the plug seated. This may cause irreparable damage to
the seating faces.
4.1.3.4 Refit the coupling (figure 16)
Refit the coupling (16.1), ensuring that the arrows
(16.2 ), embossed on the coupling halves, point upward
towards the actuator, and secure with 2 coupling
screws (16.3).
4.1.3.5 Apply supply pressure respectively vent actuator to
50% stroke and refit and tighten yoke nuts.
4.1.3.6 Connect all tubing.
