KEL
The KEL electric disc valves are designed for supply and extract air, suitable for demand controlled ventilation (DCV systems). The valves have low attenuation values and the air flow is controlled by rotating the centre disc.
The KEL disc valves can be controlled manually by switches, via CO2 sensor, humidistat or programmable switching clock. A mounting frame is included for fixing the disc valve to a wall, ceiling or circular duct. The metal disc valves are powered by 12V and are certified for reaction to fire.
