2. Use the lower packing spacer (key 12) and a tube to push the upper anti-extrusion washer (key 10) into place. Using

the lower packing spacer in this manner will ensure the upper anti-extrusion washer is fully seated and flat when

installed in the packing bore.

3. Remove the lower packing spacer from the packing bore.

CAUTION

All D3 FloPro packing kits include a single use packet of high performance fluorinated grease. This is the only acceptable D3

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.

4. Apply a 3mm (1/8 inch) bead of the supplied high performance fluorinated grease (key 44) around the groove of

the female packing adaptor as shown in figure 5 and install over the valve stem (key 16).

5. Apply a 3mm (1/8 inch) bead of the supplied high performance fluorinated grease (key 44) around the groove of

the packing ring as shown in figure 5 and install over the valve stem.

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

stem as shown in figure 3.

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 3.

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 4.

11. Torque the packing retainer to 81 NSm(60lbfSft). 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. Assemble the valve per steps 9 - 16 in the Spring-to-Close Trim Assembly section of the Valve Plug and Seat Ring

Maintenance section of this manual.
