Kombi-FC
FLOW CONTROLLER
PRODUCT DATA
Application
Kombi-FC flow controllers are installed in the return of systems with constant volume flows, for example one-pipe systems. They support a hydronic balance by keeping the flow
through consumers at a constant pre-set level even under
changing pressure conditions.
Apart from flow control the Kombi-FC also provides shutoff
and draining functions (see ‘Accessories’). The compact body
design allows installation under restricted space conditions.
Features
• Automatic flow control, infinitely pre-settable up to
000 kg/h
1
• Easy pre-setting of the flow without pipe system cal-
culation
• Leaden sealing of pre-setting possible
• Additional functions shutoff and draining
• Compact design
• Robust, low-noise and flow efficient valve housing
made of corrosion-resistant red bronze

Function
The Kombi-FC control valve is a proportional controller without need of auxiliary energy. Thereby the pressure sensing is
done before and after a throttle, which is adjusted by the
handwheel. At version DN 15 pressure sensing is done internally. At versions DN 25 and DN 40 pressure sensing is done
before the throttle by using pipes or tubes for pressure sensing. Pressure sensing after the throttle is done internally.
The flow is controlled by the differential pressure over the
throttle and kept to a constant, pre-set value.

Please Note
• To avoid stone deposit and corrosion the composition of the medium should conform with VDI-Guideline 2035.
• Additives have to be suitalbe for EPDM sealings.
• Mineral oil or any products with mineral oil content in the medium result in heavy swelling and, in most cases, failure of
EPDM sealings.
• System has to be flushed thoroughly before initial operation.
• No complaints or costs resulting from non-compliance with above rules will be accepted by Honeywell.
• Please contact us if you should have any special requirements or needs.
