1. DESCRIPTION
The Viking Standard Response ELO Upright Sprinkler VK530 is a thermosensitive
glass bulb spray sprinkler available in several different finishes and temperature
ratings to meet design requirements. The special Polyester, PTFE, and Electroless
Nickel PTFE (ENT) coatings can be used in decorative applications where colors
are desired. In addition, these coatings have been investigated for installation
in corrosive environments and are listed/approved as indicated in the Approval
Charts.
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.
On existing systems, replacing large orifice sprinklers with extra-large orifice
sprinklers may provide the higher densities required to allow an increase in the
hazard classification of an occupancy.
Viking standard response sprinklers may be ordered and/or used as open sprin-
klers (glass bulb and pip cap assembly removed) on deluge systems. Refer to
Ordering Instructions
