The Viking Corporation, a global leader in fire protection and life safety systems, announces the availability of a new 3.0 (43) K-factor residential horizontal sidewall sprinkler, Model VK479. This newest addition to Viking’s leading Freedom® residential line provides low flow requirements at smaller areas of coverage, making it a good choice for residential sprinkler systems where the available water supply is limited.

The new Model VK479 sprinkler is cULus Listed with low flow and pressure requirements for coverage areas up to 16 ft x 16 ft (4,9 m x 4,9 m). The new sprinkler is the third 3.0 K-factor residential model offered by Viking; also available are the Model VK470 pendent sprinkler and the Model VK488 flat plate concealed pendent sprinkler.  

In addition to providing the low flow requirements needed where water supplies are restricted, these small K-factor sprinklers can also provide flexibility for high-rise residential sprinkler systems.  Specifically, when used in combination with larger K-factor sprinklers, the 3.0 K-factor models can help limit over-discharge into adjacent small areas such as entryways and bathrooms.  

The new VK479 sprinkler has a ½ in (15 mm) NPT thread size and a temperature rating of 155°F (68°C).  In addition to several standard finishes, a durable ENT plating (Nickel PTFE) is available. The ENT finish is cULus Listed for use in areas subject to corrosion, such as exposed installations near the ocean.
