VK472 - Residential Pendent Sprinkler (K5.8)
Viking's Freedom® Model VK472 Residential Pendent Sprinkler has a 8.4 K-factor and is cULus listed for up to 6.1 x 6.1m coverage areas. With this larger K-factor, the VK472 can deliver the higher water densities required for an NFPA 13 residential system 0.1ft2 at lower starting pressures. Also, the 13mm NPT thread size allows for installation with a less expensive 13mm CPVC head adapter, rather than a 19mm adapter. The Electroless Nickel PTFE (ENT) coating has been investigated for installation in corrosive atmospheres and is UL Listed as corrosion resistant.
