Butterfly control valve

The butterfly valve is available in manual or motorized version and is required if the gas speed in the exhaust system becomes too strong. With this valve, the chimney draft can be especially regulated in stoves. The valve is located in the connection piece between the fireplace and the vertical exhaust system and must be able to guarantee a minimum opening in the exhaust pipe.

By turning the valve can be regulated from outside and the internal cross section of the fireplace can be influenced/changed.
