9. Unscrew the packing retainer (key 7) from the bonnet (key 2). After the packing retainer has been unscrewed from
the bonnet, pull the valve stem and plug out of the bonnet.
10. Remove the five Belleville springs (key 9), packing spacer (key 10), packing (key 11), and two anti‐extrusion rings
(key 12) from the bonnet. See figure 4.
11. Clean and inspect the packing box wall to ensure that the packing surfaces are not damaged. If the surface
condition is damaged, and cannot be improved by light sanding, replace the bonnet by contacting your
Emerson
sales office
or Local Business Partner.
12. Inspect the valve stem for scratches or wear, and valve plug for wear or damage. Replace if necessary.
13. If the valve plug requires replacement, use an appropriate tool on the machined flats located on the valve stem
above the flow adjuster and unscrew the valve plug from the valve stem. Replace it with a new valve plug. Screw the
valve plug into the valve stem, being careful not to damage the plug seat or plug contour. Tighten to 18 N
S
m (13
lbf
S
ft).
14. Inspect the valve stem bushing (key 8) located in the upper end of the bonnet. If damaged, remove and replace it
with new bushing (key 8). Replace the valve stem bushing by inserting the bushing, flange end first, into the bore
located at the top of the bonnet flow adjuster window. Insert until the flange snaps into the groove provided for it.
15. Remove the O‐ring (key 17) from the upper end of the bonnet. Replace it with a new one, and lubricate it with
lithium grease.
Assembly
1. Use the packing spacer (key 10) and a tube to push the upper anti‐extrusion washer (key 12) into place. Using the
packing spacer in this manner will ensure the upper anti‐extrusion washer is fully seated and flat when installed in
the packing bore.
2. Remove the packing spacer from the packing bore.
CAUTION
All D2T FloPro packing kits include a single use packet of high performance fluorinated grease. This is the only acceptable
D2T packing lubricant.
Note
In the following procedure, carefully install each packing ring individually over the valve stem and push completely into the
packing box with a non‐marring tube. A 12‐inch length of 1/2 inch PVC pipe works well for this. It is recommended that the
lubricated packing rings be installed individually rather than pushed in as a set.
3. Apply a 3mm (1/8 inch) bead of the supplied high performance fluorinated grease (key 38) around the groove of
the female packing adaptor as shown in figure 5 and install over the valve stem.
4. Apply a 3mm (1/8 inch) bead of the supplied high performance fluorinated grease (key 38) around the groove of
the packing ring as shown in figure 5 and install over the valve stem.
5. Install the male packing adaptor, lower anti‐extrusion washer (key 12), and packing spacer over the valve stem as
shown in figure 4.
6. Firmly press all packing parts into the packing bore with a tube.
7. Install the five Belleville springs (key 9) over the valve stem as shown in figure 4.
8. 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 4.
9. 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 2). The packing
retainer threads should be flush with the bottom of the bonnet as shown in figure 4.
