BRAHMA SOLENOID VALVE MOD. EG 12*...
The symbol EG 12*S...-E6G* normally indicates rapid closing,rapid or slow ope-
ning valves whith rapid and adjusatble release for the initial flow rate.
Version EG 12*S... (see Fig. 1) and EG 12*L...E6G* are powered by alternating
current while a rectifier circuit in the solenoid valve supplies the coil with direct
current power.
All EG 12*... solenoid have two fittings for the installation of UNI-ISO 228/1 G
1/4" pressure points. Each valve is fitted with an upstream filter to prevent the
infiltration of solid particles with f>1mm.
Solenoid valve EG 12*SR... (see Fig. 2) differs from the EG 12*S...models by the
presence of a downstream flow regolator device.
Solenoid EG 12*L...-E6G*
ner ignition by delayed valve opening throw the action of a hydrau-
lic damper installed
Solenoid valve EG 12*L...-E6G both regulates the opening time and rapid release
E
for the initial flow rate. The maximum flow rate can be regulated by adjusting the
damper block.

ADIUSTMENT INSTRUCTIONS FOR SOLENOID VALVE EG 12*...and E6G*
Flow rate adjustment:
H
To vary the gas flow rate to the burner, adjust block 3 of the time delay device
shown in Fig. 4.
Stacken the cover lock screw (only salken the screw without paint seal) and
rotate the entire unit.
Turn clockwise to reduces the flow rate and counter-clockwise to increase it.
Maximum adjustment is determined by the regulator screw stop and a thrust ring,
wich are both fitted inside the sheath.
Solenoid valve opening time adjustement:
Turn adjustment screw 1 shown in Fig. 4.clockwise to shut off the oil hole for
more rapid opening of the valve.
N.B.: Adjustement screw 1 is supplied correctly calibrated by the manufacturer
and must not therefore be re-adjustef.
Adjustement of initial flow rate rapid release:
Rotate regulator 2 shown in Fig. 4. Using a 6mm hexagonal wrench, turn the
regulator clockwise to reduce the release time and counter-clockwise to increase
it.

Flow rate adjustement:
To vary the gas flow rate, adjust regulator A using an 8 mm
hexagonal wrench or 4 mm hexagonal socked wrench
Turn the regulator clockwise to reduce the flow rate and counter-clockwise to
increase it.
