New Residential Sprinkler Provides Lowest Achievable Flow Rates

Thursday, May 24, 2012


Hastings, Michigan, USA - Viking Corporation, a global leader in fire protection and life safety systems, has added a new 3.0 (43) K-Factor recessed pendent to its Freedom® line of residential fire sprinklers. With the lowest achievable flow rates for its UL Listed coverage areas, the VK470 pendent sprinkler is optimal for any residential fire sprinkler system where the available water supply is a concern.

With its smaller K factor and low flow and pressure requirements, the VK470 may provide cost savings by enabling reduced pipe sizes, a smaller meter, or even the elimination of a tank and pump. The new sprinkler is cULus Listed for 12 x 12 ft (3.7 x 3.7 m), 14 x 14 ft (4.3 x 4.3 m), and 16 x 16 ft (4.9 x 4.9 m) room sizes. In each of these coverage areas, the VK470 provides the lowest possible flow rate for NFPA 13D and 13R residential systems requiring a 0.05 gpm/sq. ft. density design.

The new VK470 sprinkler has a ½ in (15 mm) NPT thread size and is available in 155°F (68°C) and 175°F (79°C) temperature ratings. It is offered in several standard finishes including white, ivory, chrome, and black as well as a nearly unlimited variety of custom colors. The VK470 replaces Viking’s existing VK435 sprinkler, which has now been discontinued.
