11. Place the seal positioning tool into the end of the valve body as shown above. Thread the
high pressure bushing into the valve body until light contact is made with the positioning
tool. Tighten finger-tight only. See Figure 9-30, Valve Seal Installation.
12. Apply Pure Goop anti-seize compound to the threads on the seal installation tool. Screw
the seal installation tool into the threads of the valve body. Tighten finger-tight only. See
Figure 9-30, Valve Seal Installation.
13. Lubricate the seal and the o-ring with FML-2 food grade grease. Insert the seal and o-
ring, with the bronze wedge ring, into the seal installation tool. Insert the o-ring end of the
seal first so the tapered end of the seal (wedge ring end) faces the actuator. The tapered
end of the seal must face the actuator. See Figure 9-30, Valve Seal Installation.
14. Use the seal push tool to push the seal assembly into the bore of the valve body until the
seal makes light contact with the positioning tool.
15. Remove the push tool and the installation tool from the valve body.
16. Install the existing SST backup ring and a new brass backup ring on a new stem. The vee
groove on the SST backup ring must face toward the brass backup ring. The small OD of
the brass backup ring must face toward the seal assembly.
17. Apply FML-2 grease to the tip of the stem and insert the stem with the backup rings into
the top of the valve body so the stem enters the ID of the seal assembly. Insert the stem
until the chamfer on the stem is seated against the SST backup ring. See Figure 9-31,
Valve Stem Placement
.
Do not push the o-ring on the seal assembly past the inlet port on the valve body.
This will damage the seal o-ring.
