Valve lindab | air valves KIR Technical data Without sector plate Air flow, q [l/s] and [m3/h], total pressure drop, Δpt [Pa], throw length, l0,2 [m], and A-weighted sound power level, LWA [dB], for different settings, a [mm], are shown in the graphs. Maximal vertical width, bv [m] and Maximal horisontal width, bh [m], are shown in the tables. Sound power level, LWok [dB], in octave bands is calculated as LWA + Kok. Kok is found in the table below.
