Replacing Packing
(Continued)
10. Replace pin (A46) in valve shaft (A4) (does not apply to valves with stepped shafts).
11. If the valve has single packing, re-mount the actuator bracket on the valve and tighten the screws
as shown in Table A (page 17).
12. Mount the actuator on the valve
—see actuator instructions.
13. If the actuator is a powered actuator, reconnect power to the actuator.
14. Actuate the valve. If necessary, adjust the position stops
—see actuator instructions.
15. Pressurize the valve.
16. If the packing leaks, tighten the gland nuts evenly and slowly, just enough to stop the leak.
17. If the valve has dual packing, remove the pipe plug from one of the sensing ports in the secondary
packing chamber.
If leakage occurs through the sensing port on valves with the graphoil dual-seal packing option,
tighten the gland nuts evenly and slowly, just enough to stop the leakage and replace the pipe
plug.
If leakage occurs through the sensing port on valves with the PTFE dual-seal/mechanical spring
packing option, repeat the steps in this section, starting with step 1, and replace the packing
components located in the valve body, below the secondary packing chamber.
