Viking Fire Protection J-1 Vertical Brass Alarm Check Valve

The Viking Model J-1 Vertical Brass Alarm Check Valve operates as a primary control assembly in wet-pipe fire sprinkler systems. Installed directly into the system riser, this valve traps pressurized water within the piping network to maintain system readiness while actively preventing dangerous reverse flow. During a sprinkler activation event, internal pathways route water to trigger an alarm pressure switch or water motor alarm, providing immediate notification to building occupants and safety personnel. This assembly meets critical code requirements under NFPA standards governing the design, installation, and testing of water-based fire protection systems, satisfying compliance mandates for life safety and property protection in commercial and industrial facilities.

• Brass Construction: Crafted from high-quality, corrosion-resistant brass to withstand high-pressure environments and ensure long-term durability.
• Vertical Orientation: Designed specifically for space-efficient vertical riser installations and streamlined plumbing integration.
• Reverse Flow Prevention: Maintains optimal system water pressure and directional control to protect the supply against contamination.
• Alarm Integration: Features dedicated ports to connect with water motor alarms or alarm pressure switches for instant emergency signaling.

Contractors must verify all local Authority Having Jurisdiction (AHJ) mandates and consult the manufacturer's engineering guidelines prior to system layout and installation.
