Flomatic Disassembly – Figures 4A - 4D<br />
1. Turn the cap screws (#1) counterclockwise. Remove cap screws<br />
and lockwashers (#2).<br />
2. Remove the strainer (#3).<br />
3. Loosen the set screw (#5) located on the side of the cylinder.<br />
4. Carefully remove the cylinder (#4) by turning it counterclockwise<br />
and threading it off the body. Use caution when removing cylinder!<br />
The return spring (#6) will push the cylinder upward.<br />
5. Remove the loose return spring (#6) and screen fi lters (#7) from<br />
the top of the piston assembly (#8).<br />
6. Place the valve body in a horizontal position on a workbench<br />
to gain access to lower part of valve.<br />
7. Remove the piston retainer assembly (#15) by turning it<br />
counterclockwise until it disengages from the lower body.<br />
8. Remove the large piston and seat disc assembly (#8) from<br />
the top of the valve.<br />
9. Remove the packing nut assembly (#40) by turning it<br />
counterclockwise until it disengages from valve body and<br />
indicating stem (#36).<br />
10.Remove indicating stem (#36) by fi rst pulling it into the valve<br />
body, then pull it out through the top of valve.<br />
11.Remove fi lter (#10) by turning counterclockwise and discard.<br />
Servicing the Large Piston and Seat Disc Assembly (#8)<br />
Note: Carefully inspect the pilot piston (#26) and inside walls of<br />
cylinder (#4) before starting service. If any signs of wear, nicks, or<br />
gouges appear on either of these components, discard and replace<br />
that component. A smooth machined fi nish on the pilot piston and<br />
cylinder is essential for proper valve operation.<br />
X-Seal Replacement – Figures 4A and 4B<br />
1. Turn cap screws (#16) counterclockwise and remove.<br />
2. Lift off the X-seal retainer.<br />
3. Remove the X-seal (#17).<br />
4. Inspect area of piston where X-seal was removed. Carefully<br />
clean if necessary.<br />
5. Install new X-seal and replace the X-seal retainer.<br />
6. Reinstall cap screws and securely fasten. Follow tightening<br />
sequence shown in Figure 2.<br />
