VS-3 & VS-4 Valves - Reassembling
For reassembly, refer to Figures 18 & 19 or the parts
breakdown on Pages 21 & 23.
1. Place the O-Ring (Item 455) on the guide (Item 354).
2. Place the upper seal (Item 453) and the bonded seal
ring (Item 354) onto the guide (Item 138).
3. Place the two retainer ring guides (Item 139) on the
guide.
4. Place the guide (Item 138) into the valve.
5. Secure this assembly using the four screws (Items
627) and lock washers (Item 745).
6. Reassemble the valve by placing the dashpot washer
and retaining ring on the end of the guide shaft.
7. 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.
8. 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).
9. When the cap rests against the valve housing evenly,
tighten all four screws in a crossing pattern.
10. If the valve shaft components were removed for
inspection or replacement, reassemble the valve
shaft components following the drawing to the right.
11. Insert the O-Ring (Item 451), the Inner bearing (Item
260), the next O-Ring (Item 456), 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. Be sure to check for leaks. Refer to
Pages 12 & 13 for installation instructions.
