DESCRIPTION
R 120 .../B regulators are designed to regulate gas for
medium and high pressure applications. They use a direct
action type of regulation with a balanced seat disc,
membrane action and adjustment spring.
They are used both for G.N., G.L.P. and other non-corrosive
gas installations as well as stage 1 regulators.
They can also be fitted with a VIS safety valve with minimum
and maximum pressure - this model is the R-120/B.
It consists of the regulator with the output pressure gauge
fitted as an option and the block group, in model R-120.../B.
MODELS
Two models are manufactured, covering the most typical
ranges of pressure in gas installations:
Model R-120 ES, with outlet pressure from 150 to 800 mbar
Model R-120 HP, with outlet pressure from 600 to 4000 mbar
INSTALLATION
Before installing the regulator, ensure that:
The regulator selected (see label) coincides with
the needs of the installation.
The fluid passes through the body of the
regulator in the correct direction, as indicated on
the arrow on the body of the regulator.
The tubing has been previously clean and the
gas reaches the regulator perfectly clean and
dry.
The regulator must positioned so that there is
sufficient room for maintenance to be carried out
and for the outlet pressure to be adjusted and so
that it complies with maximum and minimum
safety levels.
The regulator is protected from rain and from
direct sunlight.
There is a tank that, with the regulator at
maximum flow, has a capacity of 240 litres for
the R-120ES model and 120 litres for the R-120
HP model. For lower flow levels, the size of the
tank can be reduced proportionally.
Where condensation effects are anticipated,
install the regulator upside down (position A),
first making a 2mm hole in the lower plastic
cover. It can be installed side on (position B and
C), installing the venting cover on the lower side.

- Page 2 TYPICAL CHART STARTING UP THE REGULATOR WITHOUT VIS Provide a light flow of gas downstream from the regulator. For example, using the bleed valve V2 Slowly open the gas shutoff valve V1 slightly, situated upstream from the regulator. Check that the gas pressure is correct, using the inlet pressure gauge M1. Check that the pressure is stable, using the outlet pressure gauge M2.
- Page 3 CHECK Regulator without VIS and without VES Check that the valve (V1) at the inlet to the regulator (R), the valve (V3) at the outlet to the regulator and the bleed valve (V2) are closed. Slowly open the inlet valve (V1) and use the pressure gauge (M1) to check that the pressure is correct at the inlet to the regulator (R).
