Viking Freedom® Residential Concealed Pendent Sprinkler VK468 is a small high-sensitivity glass bulb residential sprinkler for use with a domed cover assembly. The orifice design, with a K-Factor of 4.9 (70.6 metric*), allows the sprinkler’s ef-ficient use of available water supplies for the hydraulically designed fire-protection system. The glass bulb operating element and special deflector characteristics meet the challenges of residential sprinkler standards.

Concealed sprinkler VK468 is pre-assembled with a threaded adapter for instal-lation with the domed cover that provides up to ½” (12.7 mm) of vertical adjust-ment. The cover plate is available with 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. The “push-on”, “thread-off” design of the concealed cover plate assembly allows easy installation of the cover plate after the system has been tested and the ceiling finish has been applied. The cover assembly can be removed and reinstalled, allowing temporary removal of ceiling panels without taking the sprinkler system out of service or removing the sprinkler.

The Electroless Nickel PTFE (ENT) coating has been investigated for installation in corrosive atmospheres and is C-UL-US-EU Listed as corrosion resistant as indicated in the Approval Charts. The ENT finish is only available for the sprinkler assembly, the cover plate is not plated.
