1.- Introduction.
GENERAL INFORMATION
The EVO series electro valves are usually closed; the opening is maintained by an electromagnetic
coil under tension. These valves are manufactured to ensure the interception of combustible, sending
danger signals by gas leak detectors as well as for lack of current of the electric supply; in these cases
the electromechanical device releases the shutter that closed the valve Lodge and blocks the passage
of combustible. The rearming is done manually to identify the causes of the emergency; also, for more
security, these valves can only be rearmed if there is voltage in the network and only when the gas
leak detector does not emit warning signs (positive security). Once eliminated the gas leak or restored
the electric current, to replace the valve to the opening position, it is necessary to act manually pulling
upwards the knob placed on the valve hose.

Materials: Valve body in brass; internal components and resort of stainless steel; retention ring and
O-ring of NBR nitrilic rubber.
3.- Installation
The assembly is not relevant; when horizontal tube it is recommended to maintain the electro valve
hose turn upwards. The valve assembly in the installation should be done with special tools, which
have to be introduced in the input and output orifice cubes.
It is absolutely forbidden to assembly the valve levelling with the hose. Make sure that the pipes are
clean and aligned so the valve is not fixed to excessive strength. Do not obstruct the knob route as the
valve would not work. Make sure that the voltage, pressure, temperature, etc values, indicated under
the technical features are not exceeded.
Respect scrupulously the fuel flow sense indicated by the arrow in the valve.
Power supply cable 3 x 0,75 mmq H05 VV-F
4.- Maintenance
The electrovalves do not require any maintenance. In case of failure it is recommended a general
review and the corresponding test in the plant. NOTE: It is advisable to periodically control the valve
operation by disconnecting the voltage, in order to check its perfect efficiency.
ALL INSTALLATION AND MAINTENANCE OPERATIONS SHOULD BE ACHIEVED BY QUALIFIED
PERSONNEL ONLY.
