EG12* ... SERIES
DESCRIPTION
SOLENOID GAS VALVES WITH 1/2”
CONNECTION AND OPERATING This series of solenoid gas valves are of normally closed
type, suitable for civil and industrial applications, supplied
PRESSURE UP TO 500mbar with alternate or direct current and inclusive of a wire-net filter
on the inlet to avoid the entrance of dirt of > 1 mm.
Gas valves marked with “S” or “L” after reference type have
direct current supplied coil, which permitted to make actions
as silent as possible.
There is the possibility to have a fast opening or a slow
opening valve (obtained by special hydraulic shock-
obsorber), with flow adjustment and fast opening initial flow
adjustment and inlet pressure plugs (all of them) or outlet
plugs (excluding those with flow adjustment).
Gas valves of this series, conforming to EN161, have a CE
type Certificate (CE Reg. N° 63AQ0626) in accordance to
European Directives 90/396 and 93/68.

INSTALLATION
• Respect the applicable national and European standards
(e.g. EN60335-1) regarding electrical safety.
• Assemble the valve to the installation so that the arrow
on the valve body has the same direction as the fuel
flow.
• During the assembly of the valve to the installation
piping, avoid twisting on the sheath and always use an
hexagonal key to be fitted to the valve body.
• Make sure that no foreign matters have entered the
valve body.
• Make sure that the max. fuel input pressure never
exceeds the value appearing on the label.

DIRECTIONS FOR EG12*L... VALVES ADJUSTMENT
Flow adjustment for EG12*L... 2 1
To adjust the gas flow, you have to remove one of the two
screws used to fasten the lag group (the not enamelled one, 3
marked with 4 in Fig.1) and rotate clockwise the whole group 4
to reduce the flow or in the opposite direction to increase it.
Opening time adjustment
After removing the top protection, by rotating it
counterclockwise, you have to act on the adjustment screw,
marked with 1 in Fig.1; by rotating clockwise, the opening Fig. 1
time becomes longer, by rotating in the opposite direction, the
opening time becomes shorter.
Quick release initial flow adjustment
After removing the top protection by rotating it
counterclockwise, if you rotate clockwise the nut marked with
2 in Fig.1, the initial release will be reduced; if you rotate the
same nut counterclockwise, the initial release will be
increased.

ADJUSTMENT
Flow adjustment for EG12*R
After removing the bottom protection by rotating it
counterclockwise, rotate clockwise the nut marked with 1 in Fig. 2
Fig.2 to reduce the flow, rotate in the opposite direction to
increase the same.
