Description

The 2-1/2" Double Check Detector N Pat Grooved Butterfly Valve is engineered for fire protection systems requiring reliable backflow prevention combined with efficient flow control. Ideal for residential and commercial installations, this assembly ensures that contaminated water cannot siphon back into the potable water supply, safeguarding water quality and complying with fire safety mandates.

Technical Specifications (Material Focus):

  • Main Body: Constructed from robust ductile iron with a patented grooved end design for secure, leak-resistant connections compliant with AWWA C606 standards.
  • Valve Disc: Butterfly valve disc manufactured from corrosion-resistant stainless steel to ensure precise throttling and long service life under high-flow conditions.
  • Check Valve Mechanism: Dual spring-loaded check valves with glass-filled thermoplastic check assemblies provide positive sealing and minimal pressure loss during operation.
  • Seating: EPDM elastomer seats offer chemical resistance and a reliable airtight seal, reversible and replaceable for easy field maintenance.
  • Internal Components: All springs and fasteners are made of 300-series stainless steel for durability against corrosive environments.

Regulatory Compliance:

  • UL Listed to UL 1469 standard for fire service water control valves, ensuring readiness for life-safety applications.
  • FM Approved by Factory Mutual for performance in fire protection service environments.
  • Meets ASSE 1015 for double check detector backflow prevention devices.
  • Installation and testing protocols align with NFPA 13 and NFPA 25 standards for sprinkler systems and maintenance.

Operational Compatibility:

  • Maximum Working Pressure: Rated at 175 PSI (12.1 bar), suitable for most municipal and industrial fire protection water supplies.
  • Temperature Range: Effective from 33°F to 140°F (0.5°C to 60°C), accommodating indoor and underground installation environments.
  • Connection Type: Patented grooved end design provides rapid assembly with compatible grooved pipe, significantly reducing installation time and labor costs compared to flange systems.
  • Installation Orientation: Compatible with horizontal and vertical piping arrangements (upward flow), facilitating flexible integration within existing fire protection networks.

This assembly addresses crucial concerns in fire protection systems by preventing backflow that could compromise potable water supplies, especially where high flow rates and pressure variations occur. Its dual check mechanism offers redundancy, doubling the safety margin and providing clear diagnostic capabilities during testing. The inclusion of a grooved butterfly valve component not only simplifies flow regulation but also reduces maintenance complexity.

Designed for plumbing engineers, fire protection contractors, and facility managers seeking dependable code-compliant backflow prevention with integrated flow control, this product minimizes installation turnaround while ensuring ongoing system integrity. Its construction materials and certified standards compliance distinguish it from generic backflow assemblies, making it a practical solution where robust fire line monitoring and isolation are necessary.
