9.4 Air valve for gun cleaning
As the flame is off, the purge valve 24 opens automatically the compressed air to clean the gun. With this operation, the oil between the
valves and the nozzle is drained. The air pressure value for the gun cleaning must be setted to the pressure value of the atomization
medium, regulated in low flame (generally 1 bar), and should be adjusted throught the item 37. (see hydraulic diagram of the burner)
