VK3021 K5.6 QUICK RESPONSE PENDENT IN-RACK SPRINKLER

The Viking VK3021 Quick Response Pendent In-Rack Sprinkler is a small thermosensitive glass bulb spray sprinkler available with a pre-assembled guard in various finishes and temperature ratings to meet design requirements. The special Polyester and Electroless Nickel PTFE (ENT) coatings can be used in decorative applications where colors are desired. In addition, these coatings have been investigated for installation in corrosive environments and are Listed and Approved as indicated in the Approval Chart.

Viking Model XG Sprinkler Guards and XWU Water Shields are used in conjunction with Viking XT1 style sprinklers where allowed by the approvals. (Refer to the Approval Charts) The guards are hard-wire cages designed to encase the sprinklers and protect them from mechanical damage. They are recommended for areas where sprinklers are installed at a low elevation and/or near a high degree of human or mechanical activity.

Water shields protect the sprinkler’s heat-sensing element from water discharging at a higher elevation. Viking XT1 style sprinklers with Model XWU or F-1 Water Shields and/or XG Guards are converted to intermediate level/rack storage sprinklers. They may be used in any application where water shielding is required, such as in-rack sprinkler systems, under grating, on pilot sprinklers for deluge systems, and outdoors as a weather shield. 

NOTE: Sprinkler water shields and guards are not designed to be used on sprinklers installed in recessed escutcheons

The VK3021 is compatible with revolutionary CPVC InstaSeal® technology through the addition of new Torque-Assist caps. Make sure to look for the compatibility icon to ensure the correct sprinklers are being ordered for a job requiring InstaSeal technology.
