GENERAL FEATURES

EVO solenoid valves are normally closed valves.
They are kept open by an electrically powered
electromagnetic coil.
These valves are designed to cut off the gas flow
if the gas detectors reveal a gas leak or if there
is a power blackout. In these cases the electro-
mechanical device releases the gate closing the
valve, this cutting off the gas flow. These valves
are reset manually after the cause of the emer-
gency has been removed. In addition, for greater
safety, these valves can only be reset when the
line is powered and when the gas detectors do
not reveal any danger (positive safety feature).
Once the gas leak has been eliminated, or the
electrical power restored, reset by pulling vertically
on the knob located above the valve.

non aggressive gases.
INSTALLATION
This valve can be installed in any position. On
horizontal pipes it is advisable to have the internal
duct facing upward. The valve must be installed
by inserting special tools into the hub of the inlet
and outlet openings. Never install the valve using
the duct for leverage. Make certain that the piping
is clean and aligned so that the valve is not sub-
ject to excessive stresses. Do not plug or obstruct
the knob guide as this could compromise valve
function.
Never exceed the voltage, pressure, temperature,
ect. values indicated in the technical specifica-
tions. Carefully check that the fuel is flowing in the
direction indicated by the arrow on the valve itself.
Power supply cable: 3 x 0,75 mmq
When the valve is installed outdoors, it is rec-
ommended to provide protection (e.g. a canopy)
to prevent water from damaging the electrical
devices.
MAINTENANCE
The solenoid valves do not require any mainte-
nance. Incases of breakdown they should be
overhauled and tested by the manufacturer.
N.B.: we recommend periodically testing valve
operation by cutting off the power supply to make
certain that the valve is functioning properly.
ALL INSTALLATION, REARMING, CALIBRATION AND
MAINTENANCE OPERATIONS MUST BE CARRIED
OUT SOLELY BY QUALIFIED PERSONNEL.
