The 2-1/2" Double Check Detector Valve by Ames Backflows is designed specifically for professionals managing fire protection and plumbing systems that demand rigorous backflow prevention and precise flow detection. Ideal for commercial and industrial fire sprinkler installations, this valve ensures safety by preventing contamination of potable water while enabling accurate fire flow monitoring.

• Durable Construction: The main body is made of fusion-bonded epoxy-coated ductile iron (ASTM A536), offering robust corrosion resistance and mechanical strength suitable for underground or mechanical room environments.
• Corrosion-Resistant Internal Components: Incorporates 300-series stainless steel springs and fasteners, ensuring longevity and reliable function under harsh conditions.
• Advanced Valve Technology: Utilizes glass-filled Noryl™ thermoplastic check valves that maintain consistent operation across varied flow conditions for uninterrupted backflow prevention.
• Replaceable EPDM Seats: Features reversible and replaceable EPDM elastomer discs providing secure sealing and simplifying routine maintenance without system downtime.
• Precision Actuation: Equipped with a grooved gear operator conforming to AWWA C606 standards, enabling smooth, precise valve control compatible with standard grooved piping systems.
• Compliance and Certification: UL Listed to UL 1469 and FM Approved for fire protection applications, conforming to ASSE 1015 and meeting NFPA 13 and NFPA 25 installation and maintenance guidelines.
• Versatile Installation: Supports working pressures up to 175 PSI and operates reliably within a temperature range of 33°F to 140°F, suitable for both indoor and outdoor use.
• Grooved End Connections: Designed for quick and secure installation with mechanical couplings, reducing leak risks and facilitating fast disassembly for inspections or servicing.
• Flexible Orientation: Compatible with horizontal and vertical upward flow arrangements to adapt to a variety of piping layouts.

This valve system plays a crucial role in fire protection by preventing contaminants from entering potable water supplies while allowing for precise flow measurement during fire flow tests. Its corrosion-resistant materials and replaceable components minimize maintenance demands, making it well-suited for life safety applications where reliability is non-negotiable. The grooved gear operator offers efficient valve operation in confined mechanical spaces, reducing installation complexity and downtime compared to traditional flange or manual operator valves. Compliant with stringent fire protection standards, this detector valve integrates seamlessly into modern grooved piping infrastructures, helping ensure dependable performance during emergencies and routine inspections alike.
