Trouble Shooting
Trouble Shooting is a term used to indicate a systematic
approach to locate regulator malfunction. As with installa-
tion and maintenance, successful regulator troubleshoot-
ing depends on careful analysis and planning before
taking action. Regulators are relatively simple devices
with few faults. The most common faults are:
Flow at low fire position too high?
– It sometimes happens that the flow rate at low fire
position is to high. This is due to dirt at the valve
seat or disc. These parts should be cleaned with
suitable solvent.
– Spring adjustment set too high.
Air control pressure too high?
– The maximum possible gas outlet pressure is lower
than the max. air control pressure (air impulse line).
Use a reducing fitting
(Order no. GIK 15 to 50 = 03351040)
(Order no. GIK 65 to 100 = 74910779)
Regulator is not responding?
– The working or compensating diaphragm could
be broken. Should these happen in short intervals
check the diaphragms. Always use special air dia
-
phragms for air media.
