Fig. 1: Series 1 On-Off Actuator, Air-to-Open
Service to the actuator is best performed when the actuator is removed from the valve body. For the purpose of these instructions,
consider the actuator as a separate subassembly with the procedures described in these instructions being performed on a bench.
However, many service repairs and adjustments can be accomplished in the field while the actuator and valve body are still connected
to each other.
6 REMOVING AND INSTALL ACTUATOR
6.1 REMOVING ACTUATOR
(refer to Fig. 1)
6.1.1 Shut off air supply.
WARNING: Depressurise the line to atmospheric pressure
and drain all fluids from the valve before working on the
actuator. Failure to do so can cause serious injury.
6.1.2 Disconnect all tubing.
6.1.3 Remove 2 screws (13) and remove coupling (12).
6.1.4 Remove yoke rod retaining nuts (15) and lift actuator
assembly from the valve.
6.1.5 Remove coupling insert (14) and it’s locknut from plug stem.
NOTE: Ensure that the plug assembly is not rotated with the
plug seated. This may cause irreparable damage to the
seating faces.
6.2 INSTALL ACTUATOR
(refer to Fig. 1)
The actuator stem must be fully extended:
Actuators with air-to-open action must be fully vented.
Actuators with air-to-close action apply supply pressure.
Manually depress the plug stem to ensure the plug is fully
seated.

6.2.1 Screw coupling insert locknut and coupling insert as far
as possible onto plug stem.
6.2.2 Place the actuator assembly on the valve engaging the yoke
rod threads in the lower yoke plate and ensuring the
actuator faces in the correct direction.
6.2.3 Unscrew the coupling insert until the 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.
6.2.4 Refit the coupling (12), ensuring that the arrows, embossed
on the coupling halves, point upward
towards the actuator, and secure with
2 retaining screws (13).
6.2.5 Apply supply pressure resp. vent
actuator to half stroke and refit and
tighten yoke rod retaining nuts (15).
6.2.6 Connect all tubing.
STOP!
