4. Refer to figure 2 for the desired orientation of the housing (key 21). Secure the housing to the mounting yoke with
the cap screws (key 24).
5. Apply lithium grease lubricant (key 93) to the surfaces of the sliding seal (key 19). Refer to torque values shown in
table 3. Be sure the O‐rings (keys 17 and 18) are inserted correctly.
Note
When assembling parts, make sure that all O‐rings are positioned correctly as shown in figures 8, 9, and 11.
6. Install the seal support cylinder (key 20), the thrust washer (key 74), the sliding seal, and the cylinder flange (key 2)
and secure these parts with the cap screws (key 22).
7. If 60‐degree rotation is specified, a travel stop (key 15) will be threaded into the cylinder flange on size 30 to 100.
For size 130, a travel stop and travel stop sleeve (keys 15 and 6) will be put into the cylinder flange.
8. Apply lithium grease lubricant (key 93) to the valve shaft. Refer to the appropriate valve instruction manual for
lever/valve shaft orientation marks, and slide the lever (key 28) into place. See figure 3 for correct lever operating
clearance.

For Size 80, 100 and 130 actuators, rotate the set screw (key 82) clockwise slightly to spread the split portion of the
lever and allow easy installation onto the shaft. After the lever is properly positioned, back‐off the set screw so that the
lever can be clamped to the shaft.
9. Hold the lever in place (see figure 3), and clamp the lever to the valve shaft with the cap screw (key 29).
10. Apply lithium grease lubricant (key 93) to the sealing surface of the piston rod (key 10) and apply anti‐seize sealant
(key 91) to the tapered end of the piston rod on all sizes except 130.
11. Attach the piston (key 7) to the piston rod, applying thread locking adhesive (medium strength) (key 92) to the
threads (key 9 or 10):
a. For Size 30, 40, and 60 actuators: Secure it with the cap screw and washer (keys 9 and 77).
b. For Size 68 actuators: Secure it with the hex nut and washer (keys 9 and 77).
c. For Size 80 and 100 actuators: Secure it with the hex nut (key 86).
d. For the Size 130 actuator a piston rod assembly fixture (figure 4) is recommended to properly assemble the piston
to the piston rod because of the high torque required and the need to properly protect the sealing surface of the
