DESCRIPTION <br /> The Viking Standard Response ELO Upright Sprinkler VK530 is a thermosensitive m <br /> glass bulb spray sprinkler available in several different finishes and temperature <br /> ratings to meet design requirements.The special Polyester,PTFE,and Electroless <br /> Nickel PTFE (ENT)coatings can be used in decorative applications where colors <br /> are desired. In addition, these coatings have been investigated for installation f = �- <br /> in corrosive environments and are listed/approved as indicated in the Approval <br /> Charts. t. <br /> The extra-large orifice provides greater flows at lower pressures than standard <br /> orifice or large orifice sprinklers. This feature allows reduced pipe sizing for <br /> hydraulically calculated sprinkler systems, which require high densities of water. <br /> On existing systems, replacing large orifice sprinklers with extra-large orifice <br /> sprinklers may provide the higher densities required to allow an increase in the <br /> hazard classification of an occupancy. <br /> Viking standard response sprinklers may be ordered and/or used as open sprin- <br /> klers (glass bulb and pip cap assembly removed) on deluge systems. Refer to <br /> Ordering Instructions below. NOTE:As of May 2018 all logos have been removed from the <br /> wrench boss. <br /> 2.
