VK532 - EC/QREC Upright Sprinkler (K11.2)

Viking EC/QREC Upright Sprinkler VK532 is a thermosensitive spray sprinkler available in several different finishes and temperature ratings to meet varying design requirements. The extra-large orifice produces the flows required to meet Light and Ordinary Hazard density requirements at lower pressures than standard orifice or large orifice sprinklers. The glass bulb operating element and special deflector characteristics meet the challenges of quick response extended coverage standards. The Model VK532 is cULus Listed as standard and quick response and FM Approved as quick response. The available ENT coating has been investigated for installation in corrosive atmospheres. See technical datasheet for required design and installation criteria.
