Figure 3 Sectional View B-B
1.1 Mounting Kit Disassembly
1.1.1 Remove all operating pressure from actuator, allowing the spring to stroke.
The spring will rotate the yoke to its fail position.
1.1.2 Support the actuator with lifting straps as indicated in Figure 1.
1.1.3 Loosen and remove the fasteners (90, 100 and 110) and remove all four limit
switches from the valve mounting bracket (10). Care should be taken to
prevent any damage to the limit switches while removing them.
1.1.4 Loosen and remove the fasteners (60, 160 and 170) at the valve mounting
bracket (10) to valve interface.
1.1.5 Lift the actuator along with the valve mounting bracket (10) from the valve
stem. Ensure that the SAB (20) and actuator key (40) remain on the valve
stem.
1.1.6 Remove the SAB (20) and the actuator key (40) from the valve stem.
Ensure that the spring pin (50) is not damaged while removing the SAB (20).
1.1.7 Loosen and remove the fasteners (70 and 80) to separate the valve mounting
bracket (10) from the actuator.
1.1.8 Loosen the set screws (150) and remove the striker cam (30) and key (140)
from the valve stem of the valve.

Actuator Mounting Kit Disassembly and Reassembly
1.2 Mounting Kit Reassembly
NOTE:
All parts should be cleaned to remove all dirt and other foreign material prior to
reassembly. All parts should be thoroughly inspected for excessive wear, stress cracking,
galling and pitting. Attention should be directed to threads, sealing surfaces and areas
that will be subjected to sliding or rotating motion.
1.2.1 Assemble the striker cam (30) and the key (140) on the valve stem of the valve
and tighten the set screws (150) on the valve stem.
1.2.2 Assemble the spring pin (50) in the SAB (20).
1.2.3 Assemble the SAB (20) on the valve stem such that the cylindrical surface of the
spring pin (50) rests on the top face of the valve stem.
1.2.4 Support the actuator with lifting straps as indicated in Figure 1.
1.2.5 Ensure that valve mounting bracket (10) is located correctly at the actuator
dowel pin. Assemble the valve mounting bracket (10) on to the actuator using
fasteners (70 and 80).
1.2.6 Lift the actuator along with valve mounting bracket (10) and place it over the
valve such that actuator bore slides concentrically over the SAB (20). Care
should be taken that the keyway of the actuator bore and the keyway of the SAB
(20) are aligned and the actuator key (40) is in place in the SAB (20) keyway.
1.2.7 Assemble the fasteners (160, 60 and 170) at valve mounting bracket (10) to
valve interface.
1.2.8 Assemble all four limit switches using fasteners (90, 100 and 110) on to the
valve mounting bracket (10). Adjust the limit switches as per requirement
without damaging the cam rollers.
