Rectangular Airflow Control Valve - Kanal-KOL for Optimizing Airflow in HVAC Systems

The valve consists of a rectangular body made of aluminium profile and blades made of profiled aluminium installed in it. Under the action of the air flow when the fan is switched on, the blades are maintained in the open position. When the fan is switched off, the valve blades return to their original position and close the valve cross-section.

Kanal-KOL valves can be used to replace other network elements, e.g. as louvred inertia grids, and also instead of petal valves of CL type, check valves of rectangular cross-section of KOP type. -prevents the flow of air and non-explosive air mixtures from different rooms of one ventilation system; -prevents the ingress of outside air and precipitation into the room being served after the fan is switched off; -the transported air medium must not contain substances aggressive towards aluminium and aluminium alloys; -permissible temperature of the transported...
