Figure 8. Packing Configurations

Note

The disc must be removed from the

waterway side of the valve body, which

is the side opposite the T-slot area.

Support the valve and disc so the disc

can be easily removed from the valve

when the shaft is removed.

3. Use a pin extractor to remove the disc pins

(key 6). Select the proper pin extractor tip with

screws of proper thread size to match the thread

size in the disc pins.

4. Screw the pin extractor tip into the pin as far as

possible. With an upward, straight sliding motion,

extract the pin. Repeat the same procedure for the

other pins.

A threaded rod with an appropriate spacer and nut

can also be used as an extractor tool. If using a

threaded rod, choose a rod with threads that fit the

inside threads of the pins. The rod should extend

several inches above the disc when screwed into a

pin.

5. After screwing the rod into the pin, slide the

spacer over the rod and pin. Thread the nut onto the

rod and tighten. As the nut is tightened, it will drive

the spacer against the disc and the increasing

pressure will draw the pin from the disc.

6. Loosen the packing nuts (key 16).

7. Extract the shaft (key 4) by hand-pulling or by

using the pin extractor screwed into the end of the

shaft.

Note

Valves with a two-piece shaft use a

gasket retainer, which must be

removed before removing the lower

shaft.
