VK503 - ESFR Pendent Sprinkler (K16.8)
Viking Early Suppression Fast Response (ESFR) Pendent Sprinkler VK503 is a fast response fusible element type sprinkler designed for early fire suppression. With a 16.8 (242 metric) nominal K-Factor and special deflector, this sprinkler produces large, high-momentum water droplets in a hemispheric pattern below the deflector. This permits penetration of the fire plume and direct wetting of the burning fuel surface while cooling the atmosphere early in the development of a high-challenge fire.
The VK503 is compatible with revolutionary InstaSeal® technology(opens in a new window) through the addition of new Torque-Assist caps. Look for the compatibility icon to ensure the correct sprinklers are being ordered for a job requiring InstaSeal technology.
