FIAT IDEA LPG
SOLENOID VALVES
AND SAFETY DEVICES
The system has a solenoid valve located
on the pressure reduction unit and a so-
lenoid valve fitted inside the multivalve as-
sembly on the tank.
The main function of these solenoid valves
is to interrupt/allow the flow of LPG to
the supply circuit.
The solenoid valves are open when:
– a request to run on LPG has been made;
– optimum engine conditions are satisfied
(engine coolant temperature, minimum
revs level) for running on LPG;– there is enough LPG in the tank for op-
eration;
The multiple valve assembly fitted on the
tank includes:
– a valve that automatically stops the sup-
ply of LPG when the maximum permitted
filling level is reached (80% of the total
tank capacity);
– a flow limiter which, if a pipe is broken,
prevents the complete and sudden escape
of LPG;
– a one-way valve, located on the gas re-
turn pipe in the tank, which prevents LPG
reflux;
– a safety solenoid valve on the LPG sup-
ply, which either gives the go ahead or
prevents the escape of gas to the pressure
reduction unit; – a manual tap, upstream of the solenoid
valve, that separates the tank from the
LPG system to allow maintenance work;
– a fuse pad which, in the event of
overheating (temperature above 120°C),
totally eliminates the danger of excess
pressure making the LPG in the tank flow
out as quickly as possible in a controlled
manner;
– an analogue gauge showing the level of
LPG in the tank.
