The FE series two-stage pressure regulators have a
vast range of applications both in industrial and
domestic installations.
These regulators (figs. 1 and 2) have been designed
for direct installation on user meters or on multiple
users.
They are suitable for use with previously treated
non-aggressive gases.
They can be installed in any pasition in environments
or premises protected from the weather.
The relief discharge can be conveyed to the exterior
when installed indoors.
Thanks to the design with double balanced regulation stage, the following are assured:
- high accuracy
- high service reliability.

The pressure regulator is selected by referring to the
nominal flow rate which the regulator itself can supply.
The following models are available:
FE6
6 Stm/h*
FE10 10 Stm/h*
FE25 25 Stm/h*
FE50 50 Stm/h*
* (capacity referred to natural gas with a density of
0.61).
The FE regulators can also be used with inlet pressures lower than those specified; in this case the
capacity of the regulator is lower than the values
specified above.

The FE pressure regulators are fitted with the following
devices:
- incorporated filter at the regulator inlet in drawn
sheet metal; this withholds solid impurities which
could damage the seal seat
- over pressure slam- shut : this can be set and it
blocks the supply if the downstream pressure rises
above the set point of the slam-shut itself
- under pressure slam- shut : the setting is fixed (to be
setted for FE 50); it blocks the supply if the downstream pressure drops below 85% of the set-point of
the regulator
- slam- shut for over flow : the setting is fixed; it blocks
the supply if the flow rate supplied reaches values
greater than about 85% of the set-point of the regulator
- slam- shut for over flow : the setting is fixed; it blocks
the supply if the flow rate supplied reaches values
greater than about 140% of the nominal value
- slam- shut for feeding failure : the setting is fixed; it
blocks the gas supply if the feeding line upstream
fauls
- relief valve: can be set; this releases small quantities
of gas if there are overpressures downstream from
the regulator due, for example, to increases in the
temperature of the gas when flow is zero
- anti reset device (for FE 6, 10, 25 only): this device,
installed upon request, is designed to avoid that
regulator can be put in service by a pressure source
from downstream side after slam shuts for over flow
or under pressure have tripped.
The slam- shuts can only be reset manually.
