4" Commercial Riser GXG With PRV

The 4" Commercial Riser GXG with Pressure Reducing Valve (PRV) by AGF Manufacturing serves as a critical component in commercial wet fire sprinkler systems. Installed directly into the main water supply riser, this pre-assembled manifold regulates downstream water pressure to prevent equipment overpressurization while streamlining system monitoring, testing, and maintenance operations.

Engineered to comply with strict fire protection safety guidelines, this assembly fulfills the system design mandates outlined in NFPA 13 for commercial fire sprinkler installations. The integrated pressure-reducing valve maintains optimal operating pressures across the system network, protecting downstream components from excessive line pressure while the built-in test port allows contractors to execute required hydrostatic testing without draining the entire piping network.

• Corrosion-Resistant Body: Manufactured from rugged, commercial-grade materials built to withstand long-term operational demands in building riser rooms.
• Integrated Pressure Reducing Valve (PRV): Automatically regulates and stabilizes downstream water pressure to protect system piping and sprinkler heads from damaging pressure spikes.
• Built-In Test Port: Facilitates efficient hydrostatic testing and routine drain operations without requiring full system drainage, significantly reducing inspection downtime.
• Flexible Connection Options: Features compatible grooved (GXG) and threaded connections to streamline integration into both new installations and existing retrofit layouts.
• Service-Friendly Layout: Equipped with accessible components and replaceable pressure gauges to expedite routine servicing and code compliance inspections.

Contractors and facility managers must verify all local Authority Having Jurisdiction (AHJ) mandates and consult the manufacturer's engineering data sheets prior to beginning riser installation.
