lindab | air valves Valve KIR Technical data Without sector plate Air flow, q [l/s] and [m 3 /h], total pressure drop, Δ p t [Pa], throw length, l 0,2 [m], and A-weighted sound power level, L WA [dB], for different settings, a [mm], are shown in the graphs. Maximal vertical width, b v [m] and Maximal horisontal width, b h [m], are shown in the tables. Sound power level, L Wok [dB], in octave bands is calculated as L WA + K ok . K ok is found in the table below.
