Monday, September 21, 2020 - 11am


Hastings, Michigan – The Viking Corporation announces availability of a new specific application sprinkler designed to protect challenging attic spaces. The 5.6 K-factor “Model V-EP” VK690 allows for an enhanced system design which eliminates the need for additional branch lines, reducing installation and materials costs. In addition, the sprinkler can reduce flow and pressure requirements compared to other attic protection schemes.

When used in conjunction with Viking’s existing Model VK697 5.6 K-factor attic upright sprinkler, the new Model V-EP attic sprinkler can protect up to 80 ft roof spans using 3 branch lines, and up to 100 ft spans with a 5 branch line design, with roof pitches ranging from 2½:12 through 6:12. Additionally, the VK697 and VK690 used together allow for flows as low as 20 gallons per minute and a minimum operating pressure of 13 psi. Thorough design criteria may be found on the sprinkler’s technical data sheet.

The cULus Listed sprinkler is available in brass or corrosion resistant ENT plating. With a thread size of 1/2” NPT or 15 mm BSPT, the 5.6 (80) K-factor sprinkler can be ordered with an intermediate temperature rating of 200° F (93° C).

The product joins Viking’s complete line of attic sprinklers, which also includes back-to-back, single directional, and HIP style sprinklers.
