GUIDE
A ratio regulator is used to
control the air/gas ratio. The
ratio regulator is a sealed unit
that adjusts the gas flow in ratio
with the air flow. To do this, it
measures the air pressure with a
pressure sensing line, the impulse
line. This impulse line is
connected between the top of
the ratio regulator and the air
supply line.
The cap must stay on the ratio
regulator after adjustment.
A CRS valve is used in a high/
low time-proportional control
system to quickly open and
close the air supply.
The schematics show the
advised positions of the
pressure taps.
The impulse line connects the
ratios regulator to the air
supply line.
