Valve KDPF Overview

Description:
The Valve KDPF is designed for exhaust air applications and can be mounted on walls or ceilings. It features flat spring holders that connect to various sockets including VRGU, VRGL, VRGM, VRFU, or VRFM.

Materials and Finish:
The valve is made of plastic and is available in white, specifically RAL 9003.

Dimensions:
An example of ordering dimensions is KDPF 100, with a nominal diameter (Ød) of 100 mm and an outer diameter (ØD) of 133 mm, weighing 0.06 kg.

Technical Data:
The technical data includes air flow rates (q) in liters per second (l/s) and cubic meters per hour (m3/h), total pressure drop (Δpt) in Pascals (Pa), and A-weighted sound power level (LWA) in decibels (dB) for various settings, indicated by the number of open holes.

Sound Measurement:
Sound power levels (LWok) in octave bands are calculated as LWA plus a correction factor (Kok), which is provided in a table. Sound attenuation (ΔL) is also detailed for different center frequencies (Hz) when the diffuser or valve is mounted in a duct.

Graphical Data:
The document includes graphs showing the relationship between air flow, pressure drop, and sound power level for different numbers of open holes, providing a visual representation of performance metrics.
