4. With the air relief vent valve clamped, as described above, break
the existing tamper proof seal.
• For leaded wire seals: cute the wire, remove wire from bolt
and discard.
• For cup seals (as shown in items 9 and 10): Carefully pry
the cup seal away from the bolt using a flat bladed screw
driver. Discard both cup seal halves.
5. With the air relief valve clamped, as described above, remove all
four bolts (8) and washers (6).
6. When all bolts have been removed, the clamping arrangement
holding the vent cowl to the top cover should be slowly and carefully
released.
7. Fully disassemble and lay out all of the components of the valve.
8. Carefully inspect all components for signs of damage or wear.
Items 3-6 and 8-11 are contained in this repair kit and must be
replaced during rebuild.
9. Clean the inside of the top cover (2) and vent Cowl (1) taking
particular care to ensure that the valve-seating surface on the vent
cowl is free of surface contamination. Vent cowl seating surface must
be clean and smooth to create proper sealing surface, sanding with
200-400 grit sandpaper is recommended. Ensure that all debris is
removed from the interior of the top cover (2). Blow out as required,
since, residual debris may prevent the valve from operating correctly.
10. Layout the contents of the valve and replace items 3-6 and 8-11
with the parts included in the kit.
11. Spacers may be found in your existing valve. These spacers are
to be discarded. This repair kit contains a spring, with either a +2–0
PSI, or +/-1 PSI tolerance (dependent on kit purchased), that should
provide the correct valve opening pressure without the use of
spacers. NO SPACERS ARE TO BE USED WITH THIS REPAIR
KIT. Please note that although the springs have been factory set to
provide the required opening pressure, individual variables related to
specific valves and their applications might result in a rebuilt valve
having an opening pressure that falls outside of the expected
tolerance band. . In the event that the required opening pressure
(either 15 PSIG or 18 PSIG as noted on the kit) cannot be obtained
through use of the spring alone, ensure that you have the correct
repair kit and contact your Dixon Bayco sales representative
immediately.
