AND OPERATING

GENERAL DESCRIPTION

This series of solenoid valves are of normally closed type,
suitable for civil and industrial applications, supplied with
alternate or direct current and inclusive of inside rectification
circuit which permitted to make actions as silent as possible;
a wire-net filter on the inlet avoids the entrance of dirt
of > 1 mm.
There is the possibility to have a fast opening or a slow
opening valve (obtained by special hydraulic shock-
absorber), with flow adjustment and fast opening initial flow
adjustment.
All versions can be supplied with gas pressure switch and
gas pressure test points upstream and downstream.
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.
− EC- type certification in accordance with the new
European Gas Appliances Regulation (EU) 2016/426
(GAR);
− conformity to EC Low-voltage directive 2014/35/EU

DIRECTIONS FOR INSTALLATION AND MAINTENANCE

•
This valve is a safety appliance and should not be
modified. The manufacturer's responsibility and guarantee
are invalidated in case the device is tampered with by the
user.
•
The applicable national regulation and European
standards (Ex. EN 60335-1 and EN 60335-2-102) related
to the electrical safety must be respected;
•
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 wrench 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.
•
All operations (installation, maintenance, etc.) must be
carried out by a qualified technician.
•
Before any connection operation, completely isolate the
system from power supply (multi-pole disconnection).
Place the system safely to avoid accidental switch-on and
make sure there is no voltage. If the system is not
switched off, there is a risk of electric shock.
