FIAT PANDA 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 multiple valve
assembly 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;
– the optimum engine conditions are sat-
isfied (engine coolant temperature, mini-
mum revs level) for running on LPG;– there is enough LGP in the tank for op-
eration;
– the inertia switch has not been tripped.
The multivalve 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 opera-
tions;
– 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.
