Viking Introduces New 3.0 K-Factor Residential Concealed Sprinkler

Wednesday, May 8, 2019 - 11am


Hastings, Michigan, USA – The Viking Corporation, a global leader in fire protection and life safety systems, has added a new 3.0 (43) K-factor residential flat plate concealed pendent sprinkler to its leading Freedom® residential product line. The new model VK496 is cULus Listed with a flow rate of only 8 GPM (30 L/min), and a pressure requirement of only 7.1 PSI (0.49 bar) in a 12 x 12 ft (3,7 x, 3,7 m) room size.

With its smaller K-factor and lower flow rates, the new glass bulb sprinkler is appropriate for NFPA 13D residential systems where the available water supply is a concern. In these systems, the VK496 could allow for reduced pipe sizes, a smaller water meter, and/or the elimination of a tank and pump. In addition to the 12 x 12 ft (3,7 x 3,7 m) room size indicated above, the new sprinkler is also cULus Listed for 14 x 14 ft (4,3 x 4,3 m) and 16 x 16 ft (4,9 x 4,9 m) coverage areas.

The Model VK496 features a flat cover plate and is well-suited for residential applications where a concealed appearance is desired. The new sprinkler joins Viking’s industry-leading line of flat plate concealed residential sprinklers which now includes three pendents (3.0K VK496, 4.9K VK494, 5.8K VK498) and two sidewalls (4.0K VK480, 5.8K VK490). The VK496 replaces the previous Viking Model VK488.

Available in both 155°F (ordinary) and 200°F (intermediate) temperature ratings, the Model VK496 has three cover plate styles (standard diameter, large diameter, and square). In addition to nine standard finishes and unlimited custom color options, the sprinkler is also available with an ENT finish for installation in certain environments where corrosion is a concern. The VK496 has a ½” (15 mm) NPT thread, and uses the same installation wrenches as Viking’s Mirage® commercial concealed pendent sprinkler.
