VK580 - Upright Sprinkler (Storage-Density/Area) (K16.8)

Part Number:

Viking Standard Response Upright Sprinkler VK580 is a thermosensitive glass bulb spray sprinkler available in various temperature ratings to meet design requirements. With a 16.8 nominal K-Factor, the sprinkler provides greater flows at lower pressures than sprinklers with smaller K-Factors. This feature allows reduced pipe sizing for hydraulically calculated sprinkler systems, and provides the higher densities required to allow an increase in the hazard classification of an occupancy. Viking Standard Response Sprinkler VK580 was subjected to full-scale high piled storage fire testing and is cULus Listed and FM Approved for use in protecting high-piled storage.
