14. Install the packing flange. Properly lubricate the packing flange stud bolts and the faces of the packing flange nuts.
For graphite packing, tighten the packing flange nuts to the maximum recommended torque shown in table 6. Then,
loosen the packing flange nuts, and retighten them to the recommended minimumtorqueshownintable6.
For other packing types, tighten the packing flange nuts alternately in small equal increments until one of the nuts
reaches the minimum rec ommended torque shown in table 6. Then, tighten the remaining flange nut until the
packing flange is level and at a 90-degree angle to the valve stem.
15. Install the travel indicator parts and stem locknuts; mount the actuator on the valve body according to the
procedure in the appropriate actuator instruction manual.
