1. DESCRIPTION
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.
2. LISTINGS AND APPROVALS
