Viking VK467 Residential Fast Response Brass Upright Fire Sprinkler delivers powerful, affordable fire suppression in ordinary hazard residential occupancies such as homes, apartments, dormitories, and hotels.
Using a heat-activated 3mm red glass bulb, this automatic fire sprinkler opens when ambient temperatures reach 155F (68C), supporting rescue and evacuation efforts by lowering ambient temperatures. Designed for residential applications, the 4.9K orifice makes efficient use of available water supplies in smaller sprinkler systems.
Viking's Freedom Residential Upright Sprinklers are designed to be unobtrusive, fast-acting, and capable of providing coverage of up to 16 feet by 16 feet (4.9 m x 4.9 m). Designed for residential applications, the 4.9K orifice makes efficient use of available water supplies in smaller sprinkler systems.
The Viking Model VK467 has a 4.9 K-Factor and installs with 1/2" (12.7 mm) National Pipe Thread (NPT), used in fire sprinkler systems throughout the United States. This Residential Fast Response Fire Sprinkler features a brass finish, brass frame, brass screw, and a spring sealing assembly made with nickel alloy and PTFE tape.
This 155F (68C) temperature rating strikes a balance between a fire sprinkler that activates too soon, causing accidental discharge, and too late. With a maximum working pressure of 155 PSI (10.7 BAR), this upright sprinkler points toward the ceiling and may be installed and used in accordance with NFPA 13, NFPA 13R, NFPA 13D and local fire code. Each Model VK467 sprinkler is made by Viking, a global leader in fire protection manufacturing for nearly 100 years.
This product is UL-listed, and appropriate for use in fire protection systems when accepted by the authority having jurisdiction. In accordance with NFPA 13, a higher temperature rating may be required when installing a fire sprinkler in or near heat sources, unventilated spaces, uncovered steam mains, or uninsulated rooftops.
