VK490 - Residential Concealed Horizontal Sidewall Sprinkler (K5.8)

VK490 - Residential Concealed Horizontal Sidewall Sprinkler (K5.8)

Viking Freedom® Residential Concealed Horizontal Sidewall Sprinkler VK490 is a small high-sensitivity solder link and lever residential sprinkler designed for installation on concealed pipe systems, where the appearance of a smooth wall is desired. The sprinkler orifice design, with a K-Factor of 5.8 (83.6 metric*), allows the sprinkler’s efficient use of available water supplies for the hydraulically designed fire-protection system. The operating element and special deflector characteristics meet the challenges of residential sprinkler standards.  The sprinkler is hidden from view by a low profile, small diameter cover plate installed flush to the wall. The cover plate is available in several decorative finishes to meet design requirements. The two-piece design allows installation and testing of the sprinkler prior to installation of the cover plate. After the system has been tested and wall finish has been applied, the push-on design of the cover plate assembly allows easy installation of the cover plate with up to 1/4” (6.4 mm) adjustment. Sprinkler VK490 is provided with a pipe guide to properly locate the sprinkler and allow the 1/4” adjustment of the cover plate.
