VFC
The linear flow control is designed to adjust volumes
of gas and cold air on various appliances. The VFC
with actuator IC 20/IC 30/IC 40 (IFC) is suitable for
regulating flow rates for control ratios up to 25:1
in modulating or stage-controlled combustion pro-
cesses.
Linear flow control VFC and actuator IC 20 or IC 40
can be supplied separately or assembled. IC 30 is
supplied separately.
This function is only guaranteed when used within
the specified limits – see also page 5 (Technical
data). Any other use is considered as non-compliant.
