VK531 - QR ELO Upright Sprinkler (Storage-Density/Area) (K11.2)

Viking is a proud world leader in the design and manufacturing of life-saving fire sprinklers. The VK531 QR ELO Upright Sprinkler is just one of thousands of industry-leading sprinklers available to customers! 

The VK531 is a thermosensitive glass bulb spray sprinkler available in several different finishes and temperature ratings to meet design requirements. The extra-large orifice provides greater flows at lower pressures than standard orifice or large orifice sprinklers. This feature allows reduced pipe sizing for hydraulically calculated sprinkler systems, which require high densities of water. Viking Quick Response Extra-Large Orifice Sprinklers may eliminate the need for a fire pump or reduce the size of the pump if it is required.
