BraHma SoLenoID VaLVe moD. eg 12*...anD
e6g* for gaS BUrnerS (LoW preSSUre)
The symbol EG 12*S...-E6G* normally indicates rapid closing,rapid or slow opening 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* (see Fig. 3) permits gradual burner ignition by delayed valve opening
throw the action of a hydraulic damper installed in direct contact with the moving part.
Solenoid valve EG 12*L...-E6G both regulates the opening time and rapid release for the
initial flow rate. The maximum flow rate can be regulated by adjusting the damper block.
Maximum guaranteed operating pressure: 250 mbar;500mbar (E6G)
Class: A
Operating temperature: -10/+60°C
Power supply: 230 V 50/60 Hz
Protection class: IP54 Operating frequency: unlimited

flow rate adjustment:
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.
