Reassembling the Valve
For reassembly, refer to Figures 7 & 10 or the parts
breakdown on Pages 17 & 19.
1. Place the seal (Item 354) into the valve housing.
2. Place the guide (Item 138) into the valve outlet.
3. Secure the seal and guide using the two screws
(Items 615). Tighten the screws.
4. Turn the valve so that the outlet faces down.
5. Reassemble the valve by placing the dashpot washer
and retaining ring on the end of the guide shaft.
6. Place the complete cap assembly on the valve
housing remembering to orient the valve handle in
the same position as it was prior to disassembling.
7. Insert the four screws and washers into the valve
cap and tighten by alternately tightening each screw
a few turns so that the cup (Item 133) slides evenly
over the guide (Item 138).
8. When the cap rests against the valve housing evenly,
tighten all four screws in a crossing pattern.
9. If the valve shaft components were removed for
inspection or replacement, reassemble the valve
shaft components following the drawing above.
10. Insert the O-Ring (Item 450), the Inner bearing (Item
260), the next O-Ring (Item 455), the next bearing
(Item 140), the shaft case seal (Item 270) and secure
with the retaining ring (Item 564).
This completes reassembly. The valve may be placed
back in service. Refer to Pages 6 & 7 for installation
instructions.
