VIKING Fireking Split Flange PN16 (VK-SFP)

The VIKING Fireking VK-SFP Split Flange PN16 is designed to provide a secure mechanical transition between grooved steel pipe and PN16 flanged components. The two-piece ductile iron housing, combined with an EPDM gasket, ensures a pressure-tight seal while allowing fast, alignment-tolerant installation without welding or threading.

Nominal Sizes: 2" to 8" (DN50 to DN200)
Working Pressure: 20.7 bar (300 psi)
Ambient Temperature: −34°C to +110°C
Housing: Ductile Cast Iron ASTM A536 Grade 65-45-12
Gasket: EPDM
Bolts & Nuts: ASTM A449, quenched and tempered
Flange Standard: PN16
Finish: Painted, Epoxy Coated, Galvanized

Enables fast connection to flanged valves and equipment
Eliminates welding and alignment difficulties on site
Allows easy disassembly for maintenance or replacement
High mechanical strength suitable for fire-protection service
Corrosion-resistant finish options extend service life

Connection of grooved fire-protection piping to PN16 flanged valves, pumps, flow switches, and other equipment in sprinkler and standpipe systems.
