VK630 - QREC Horizontal Sidewall Sprinkler (K8.0)

Part Number:

Viking Quick Response Extended Coverage Horizontal Sidewall Sprinkler VK630 is a thermosensitive spray sprinkler available in several different finishes and temperature ratings to meet varying 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 atmospheres and are listed/approved as corrosion resistant as indicated in the Approval Charts. (Note: FM Global approves the ENT coating as corrosion resistant. FM Global has no approval classification for Polyester coatings as corrosion resistant.). Refer to technical datasheet for required design and installation criteria.
