1. Unscrew cap screws (key 34), and remove the cover (key 33).
2. Proper installation of this actuator is right-hand mounted, actuator stem positioned vertically with the valve in a
horizontal pipeline.
3. Mount the actuator on the valve body and secure it with the washers and valve mounting screws. The torque for the
5/8 inch studs and nuts is 163 NSm (120 lbfSft).
CAUTION
Exceeding any torque requirement may impair the safe operation of this actuator by causing broken or damaged parts.
Refer to table 2 for the bolting torque requirements.
4. Screw the left‐hand threaded locknut (key 58) onto the diaphragm rod (key 10) as far as possible.
5. Screw the turnbuckle (key 57) as far as it will go onto the actuator rod.
6. Screw the locknut (key 16) as far as it will go onto the rod end bearing (key 17). Thread this assembly completely
into the turnbuckle (key 57).
7. If the lever (key 27) is attached to the rod end bearing, remove the cap screw and hex nut (keys 18 and 19).
8. If the 1052PSV spring adjustment has been changed, complete the Initial Setting portion of the 1052PSV Spring
Adjustment section before proceeding.
9. Slide the lever into place (see figure 5). Clamp with the cap screw (key 28).
10. Rotate the lever (key 27) to align with the rod end bearing (key 17). This connection can be aided by moving the
actuator off its up travel stop with a regulated air source and adjusting the turnbuckle (key 57) slightly.
11. Apply sealant (key 77) or equivalent thread‐locking compound to the threads of the cap screw (key 18).
12. Connect the lever (key 27) and the rod end bearing (key 17) with the cap screw and hex nut (keys 18 and 19).
Tighten the cap screw to the recommended bolt torque shown in table 2.
13. Note the valve position and direction of rotation. Position the travel indicator (key 37) according to the valve
position just noted.
CAUTION
To avoid parts damage, do not stroke the actuator while the cover (key 33) is off.
14. Replace the cover (key 33), and secure with washers (key 31) and cap screws (key 34).
