Installing Actuator

1. Place the valve plug in the position noted when the actuator was removed.

Note:

Normally this will be so the plug is in the lowest position in the valve body.

2. Line up the scribe marks on the valve and actuator made during actuator removal, then set the

actuator on the valve so that the valve shaft slides into the actuator gear sector.

3. Fasten the actuator adapter to the valve.

4. Slide the bearing washer down the plug stud.

5. Screw the plug adjusting nut down the plug stud until it touches the bearing washer.

6. Turn the plug adjusting nut clockwise until there is .010" clearance between the plug face and

the body seat. (If the valve is used with paper stock, the clearance should be .030".

Note:

The holes in the bearing washer must line up with the tapped holes in the top of the gear

sector.

7. Slide the pointer down the plug stud so that it rests on top of the bearing washer; the pointer

should point to the correct valve position. Fasten the pointer to the gear sector with the two

shorter socket head screws.

8. Slide the wrenching square down the plug stud so that it rests on top of the pointer. Fasten the

wrenching square to the gear sector with the four remaining socket head screws.

9. Screw the lock nut down the stud until it contacts the wrenching square and tighten to lock the

assembly into place.

10. Connect the supply pressure tubing to the cylinder.

11. Check the stop settings and readjust if necessary. The correct adjustment procedure is

described in the STOP ADJUSTMENT Section of this instruction.

12. If the actuator is a powered actuator, reconnect power to the actuator.

13. Pipeline flow may now be restored.
