VK472 - Residential Pendent Sprinkler (K5.8)

Viking's Freedom® Model VK472 Residential Pendent Sprinkler has a 5.8 (84) K-factor and is cULus listed for up to 20 x 20 ft (6.1 x 6.1 m) coverage areas. With this larger K-factor, the VK472 can deliver the higher water densities required for an NFPA 13 residential system (0.1 gpm/ft2) at lower starting pressures. Also, the ½ inch NPT thread size allows for installation with a less expensive ½ inch CPVC head adapter, rather than a ¾ inch adapter. This can significantly lower the total installed cost of a sprinkler system, particularly in a high-rise residential building.

This Freedom® line of 5.8 (84) K factor sprinklers is designed to provide for enhanced aesthetics. The VK474 flat plate concealed sprinkler is available with three cover plate options: standard round, large diameter, and square. The standard cover plate has the smallest diameter available in the industry for a less noticeable installed appearance. Additionally, Viking offers a UL Listed custom finish program for both cover plates and frame-style sprinklers. Cover plates are available in nine standard finishes and a wide variety of custom colors.

The VK472 is available in 155°F (68°C) and 175°F (79°C) temperature ratings to meet design requirements.
