V5015 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 V5015
Kombi-FC also provides shutoff and draining functions (see accessories). The compact body design
allows installation under restricted space conditions.
For hydronic heating and cooling systems.
