REPLACE REPAIR
Purification Check Valve.
a.
The purification check valve serves a dual purpose in the air system.
1.
Maintains 1800 to 2000 psi on the purification chambers when not in use (air escaping through
compressor).

Prevents sudden loading of the 4th stage in case the service line check valve fails.
b.
The purification check valve is suspect when the unit has been secured for 24 hours and when opening the bleed
valve no air is heard to escape (a leak check should be performed with unit at full pressure to ensure air did not
leak out).
c.
Removal (air bled off system).
1.
Remove service line.
2.
Remove fitting from check valve.
3.
Remove check valve.
NOTE
Repair is by replacement only. Do not attempt repair.
