Pneumatic Actuator Installation<br />

NOTE: Lubricant compound 11550-215, or the equivalent, should be<br />

applied in a light coating when specified. Torque tolerance is ±10 in/<br />

lbs. Refer to Diagram 2 during assembly of the pneumatic actuator.<br />

1. Remove the clevis and clevis locknut from the air chamber shaft.<br />

Remove the cotter pin and pivot pin from the clevis.<br />

2. Assemble the air chamber to the bracket using the air chamber nuts<br />

and lock washers. Center the air chamber shaft in the clearance<br />

hole of the bracket. Tighten air chamber nuts to 375 in/lbs.<br />

3. Reassemble the clevis locknut and clevis to the air chamber shaft.<br />

Adjust the clevis so that the center of the pivot pin hole is 2 3 /4" from<br />

the bracket with the pivot pin holes in the horizontal plane. Lock<br />

the clevis in place with the clevis locknut using 200 in/lbs. torque.<br />

4. Mount the above bracket assembly to the valve face with the<br />

bracket screws and lock washers. Be sure that the top of the<br />

bracket is even with the upper edge of the valve face and centered<br />

around the hex of the packing gland. Torque the bracket screws<br />
