Viking VXR Dry Pipe Valve System Riser

The Viking VXR Dry Pipe Valve System Riser functions as the primary control component in commercial and industrial dry pipe sprinkler systems, holding back the water supply until a sprinkler head activates. Installed directly within the system riser assembly, this differential valve maintains air or nitrogen pressure in the sprinkler piping to keep the water control valve closed until a pressure drop occurs during a fire emergency, ensuring controlled water delivery when seconds matter.

Engineered in strict compliance with NFPA 13 standards, this riser assembly satisfies code requirements for the installation and integration of dry pipe fire sprinkler systems. Adhering to these guidelines ensures your facility meets life safety mandates, simplifies regulatory inspections, and secures AHJ approval for commercial and industrial builds.
