Make sure all parts are clean and in good condition before starting assembly. There should be no burrs or sharp edges
on any threads or surfaces that might cut or damage soft parts in the valve assembly.
CAUTION
The threads on factory-produced valve stems have been specially machined to avoid O-ring, bushing, or packing damage
during trim maintenance. Use of other than a factory-produced valve stem may result in early stem O-ring, bushing, and
packing failure.
WARNING
The spring pins/pipe plugs (key 6) must a lways be in place during valve operation. They provide a safeguard against injury
when the unit is being disassembled.
1. Install the bonnet nut (key 5) and spring pins (or pipe plugs) (key 6, figures 7 or 8) if previously removed.
2. Lubricate the stem O-ring (key 25) with lithium grease and install in the bonnet (key 7).
3. Press the bonnet bushing (key 18) with the slots upward into the upper hole in the bonnet. The bonnet bushing is
installed correctly when it snaps into place.
4. Install the casing O-ring (key 17) in the provided groove at the top of the bonnet.
5. Position the lower casing (key 21) on the bonnet.
6. Install the casing locknut (key 20) on the bonnet and torque to 203 NSm (150 lbfSft).
7. Install the valve stem (key 16) from the bottom of the bonnet. Inserting the valve stem in this manner will prevent
damage to the bonnet bushing and stem O-ring.
8. Ensure the upper packing spacer (key 12) is installed.
9. 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.
10. 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.
11. 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).
12. 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.
