Supply air valve
Maximum sound power level 32 dB(A)
Quick Sizing
Type Z-LVS
Selectable nominal sizes: 100, 125, 160
Selected: Z-LVS/125
Specification text
Circular disc valves as supply air devices, preferably for small rooms. For installation into walls and suspended ceilings. Ready-to-install component which consists of a valve casing with cross bar, a valve disc with threaded spindle, and an installation subframe. The valve disc can be turned for volume flow rate balancing. The valve setting can be fixed with a lock nut. Spigot suitable for ducts to EN 1506 or EN 13180. Sound power level of the air-regenerated noise measured according to EN ISO 5135.
