Viking Offers New Residential 3.0 K Factor Flat Plate Concealed Sprinkler
Hastings, Michigan, USA – Viking Corporation, a global leader in fire protection and life safety systems, has extended its Freedom® residential fire sprinkler line to include a "small orifice", flat-plate concealed pendent sprinkler. The new model VK488 has a K Factor of 3.0 (43) and 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. This new sprinkler is offered in addition to the model VK470, 3.0 K factor residential pendent sprinkler, which Viking introduced in 2012.
With its smaller K Factor and lower Listed flow rates, the VK488 is well-suited for 13D residential systems where the available water supply is a concern. In these systems, the VK488 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 new VK488 sprinkler has a ½ in (15 mm) NPT thread size and is available with a temperature rating of 165°F (74°C). The cover plate for the VK488 is offered in three different options including standard/small diameter, large diameter, and Viking's exclusive square cover plate. All three cover plate options have a temperature rating of 135°F (57°C). Like all concealed sprinklers from Viking, flat cover plates are available in several standard finishes and a nearly unlimited number of custom colors.
