Product Description

The UL/FM Fire Alarm Check Valve is a critical component in wet pipe fire sprinkler systems, designed to prevent water backflow and trigger a pressure-activated alarm when water flows to suppress a fire. Engineered for reliability and compliance with stringent safety standards, this valve ensures rapid alarm activation while maintaining system integrity.

Features

• UL Listed & FM Approved： Certified to meet NFPA standards for fire protection systems, ensuring global compliance and safety.

• Pressure-Operated Alarm：Automatically activates a mechanical water-motor alarm or electric pressure switch when water flow exceeds a preset rate (typically 4–10 GPM).

• Non-restrictive Design：Minimal pressure loss across the valve.

• Easy Inspection：External bypass test valve for routine testing without system shutdown.

• Cast Iron or Ductile Iron Body：Epoxy-coated for corrosion resistance.

• Stainless Steel Trim：Clapper and seat assembly for longevity.
