3. Carefully tuck the O‐ring downward into the body T‐slot until the seal ring is completely entrapped in the body
T‐slot, and it completely covers the backup O‐ring.
4. Re‐install the retaining ring and the socket head cap screws. Tighten the cap screws just enough to eliminate any
movement of the retaining ring. Do not over‐tighten the retaining ring screws. Using a blunt‐end tool, carefully
tuck the lip of the seal ring under the retaining ring.
5. When the seal is under the lip of the retaining ring, continue to tighten the cap screws according to standard
procedures. Do not fully torque the screws at this time. Final tightening of the screws is accomplished in step 7 of
this procedure.
6. Manually rotate the upper shaft clockwise 180 degrees to return the disk (key 2) to its closed position.
7. The final seating of the retaining ring cap screws can now be done. For the screw torque values, refer to table 6. The
seal is now fully installed. Refer to the Installation procedures in this manual.
NOVEX, Phoenix III and/or Phoenix III Fire‐Tested Seals
1. Locate the replacement seal ring (key 5) and note the shape of the ring. The ring is wider across one edge diameter
and narrower across the other edge diameter as shown in figure 8. Around the outside circumference is one wide
groove.
Install the seal ring (key 5) in the valve body by first placing the wider outside diameter of the seal ring into the T‐slot
area of the valve body which is shown in figure 2.
The backup O‐ring (key 6) for the Phoenix III seal will have to be installed after placement of the seal ring in the valve
body using a blunt‐end screwdriver or the seal installation tool in the maintenance kit. Do not use the screwdriver or
seal tool directly on the metal seat. Use tools on the O‐ring only.
2. With the seal ring inserted all the way around the body T‐slot now lay the O‐ring into the opening between the valve
body and the seal ring. Use the seal tool to apply pressure to the O‐ring and carefully tuck the O‐ring down into the
T‐slot between the valve body and the seal ring.
Note
On larger valves, it may be more efficient to have someone hold down the seal ring while you push the O‐ring into the T‐slot.
3. Once the seal ring and backup O‐ring have been fully installed into the body T‐slot, the retaining ring gasket can be
installed. This gasket is a thin graphite material. Punch one initial screw hole through the gasket for alignment,
being careful not to cause additional damage to the gasket.
4. Install the retaining ring and align the screw holes in the retaining ring with the holes in the valve body. Install the
first retaining ring screw through the punched hole in the ring gasket. Install the other ring screws by pushing the
screws through the graphite gasket and threading them into the valve body.
5. Tighten the retaining ring socket head cap screws just enough to eliminate any movement of the retaining ring. Do
not over‐tighten the retaining ring screws.
WARNING
Avoid personal injury or property damage caused by the impact of a falling or tipping of a large valve. Support large valves
during maintenance.
6. To complete this step, stand the valve up. Support the valve securely using methods appropriate for the valve size.
If a vise or other clamps are being used, be sure to not damage the flange gasket sealing area of the valve body.
