VK2503, VK2523, VK2543 - Ordinary Hazard Dry Horizontal Sidewall Sprinklers (K8.0)

Viking is a proud world leader in the design and manufacturing of life-saving fire sprinklers. The VK2503, VK2523 and VK2543 Ordinary Hazard Dry Horizontal Sidewall Sprinklers are just some of thousands of industry-leading sprinklers available to customers! 

The VK2503, VK2523 and VK2543 are thermosensitive spray sprinklers suitable for use in areas subject to freezing. The sprinklers are designed for dry systems and preaction systems where it is necessary to prevent water or condensation from entering the drop nipple before sprinkler operation. They may also be installed in spaces supplied from a wet system in an adjacent heated area. The large orifice dry sidewall sprinkler allows greater flows at lower pressures than standard orifice sprinklers. 

The deflector carries an expanded approval for installation from 4” to 12” below the ceiling, allowing additional flexibility when installing sprinklers near crown moldings or other obstructions. The special Polyester and Electroless Nickel PTFE (ENT) coatings have been investigated for installation in corrosive atmospheres and are cULus Listed as corrosion resistant as indicated in the Approval Chart.
