6.  Install the male packing adaptor, lower anti‐extrusion washer (key 10), and lower packing spacer over the valve

stem as shown in figure 10.

7.  Firmly press all packing parts into the packing bore with a tube.

8.  Install the five Belleville springs (key 9) over the valve stem as shown in figure 10.

9.  Install the valve plug (key 3) on the stem and insert a new groove pin (key 43).

10.  Lubricate the threads of the packing retainer with anti‐seize and install into the bonnet using a 1‐1/8 inch wrench.

Make sure the Belleville springs are completely enclosed by the packing retainer as shown in figure 11.

11.  Torque the packing retainer to 81 N

S

m (60 lbf

S

ft). The packing retainer has been installed correctly when a

metal‐to‐metal contact has been made between the packing retainer end and the bonnet (key 7). The packing
retainer threads should be completely enclosed by the bonnet.

12.  Apply anti‐seize lubricant to the threads on the valve body and bonnet nut (key 5) and the contact surfaces of the

bonnet and bonnet nut flange. Install the bonnet and actuator assembly onto the valve body. Tighten the bonnet
nut until the nut stops turning. A few hammer blows will be required to ensure that the assembly is tight.

Stem Replacement

CAUTION

If the valve stem is replaced, the packing will also need to be replaced, since the threads on the valve stem may damage the
packing when the valve stem is removed.

1.  Follow the Trim Disassembly procedures, steps 1-8 on page 18 of this manual.

2.  Ensure power and signal have been isolated from the actuator. Open the explosion-proof enclosure (keys 60 and

61), using a 13mm wrench.

3.  Remove the FloPro (keys 13, 14, and 15), using a 5/32 inch hex head wrench.

4.  Remove the stem nut (key 27), using an 11/16 inch wrench, noting the position of the FloPro relative to the bonnet

markings.

5.  Use a rubber mallet to gently drive the stem downward through the bottom of the actuator housing and remove

the stem.

6.  Ensure the packing as been removed, using procedures in the Packing Disassembly on page 20 of this manual.

7.  Replace the stem by gently pushing the stem up through the actuator.

8.  Replace the packing and plug, using the procedures in the Packing Assembly on page 20 of this manual.

9.  Install the FloPro at the same position it was removed from in step 4. Tighten the hex socket head cap screws to 

3 N•m (26 lbf•in).

10.  Tighten the stem nut (key 27) to 39 N•m (29 lbf•ft) using an 11/16 inch wrench. Be sure the FloPro is not allowed

to rotate when tightening the stem nut.

11.  Apply anti‐seize lubricant to the threads on the valve body and bonnet nut (key 5) and the contact surfaces of the

bonnet and bonnet nut flange. Install the bonnet and actuator assembly onto the valve body. Tighten the bonnet
nut until the nut stops turning. A few hammer blows will be required to ensure that the assembly is tight.
