E8/... SERIES
SOLENOID GAS VALVES WITH 1/8” and
1/4” CONNECTIONS AND OPERATING
PRESSURE UP TO 1,5 bar.
GENERAL DESCRIPTION
This series of solenoid valves are of normally closed type,
suitable for civil and industrial applications, supplied with
alternate or direct current.
E8/S version, which can be fitted with a flow adjustment
device and outlet pressure plug, are supplied with alternate
current, but provided with an inside rectification circuit, which
permitted to make actions as silent as possible.
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.
•During and after any operation (installation, maintenance,
etc.), make sure that the type and code are the ones
provided, check the correct functioning and the internal and
external thickness of the valve.
•In the event of a fall or impact, the valves must not be
started, as safety functions may be compromised even if no
damage is visible to the outside.
•Faulty valves or damaged must be unplugged from power
supply and cannot be used.
•The valve has a designed lifetime* based on the endurance
tests in the standard EN 161. A summary of the conditions
has been published by the European Control Manufacturers
Association (Afecor) (www.afecor.org). The designed lifetime
is based on use of the valve according to the manufacturer’s
technical notes. After reaching the designed lifetime in terms
of the number of burner startup cycles, or the respective
time of usage, the valve has to be replaced by authorized
personnel.
* The designed lifetime is not the warranty time specified in
the Terms of Delivery

FLOW ADJUSTMENT FOR E8/SR...
After removing the top protection, rotate clockwise the screw
marked with 1 in Fig.1 to reduce the flow, rotate it counter
clockwise to increase the same.
