Description

Technical Specifications (Material Focus)
The Deringer 30G Double Check Backflow Prevention Valve is engineered with durable ductile iron for the main body, providing exceptional strength and corrosion resistance suitable for industrial fire protection environments. Internal components incorporate brass fittings and stainless steel springs, ensuring reliable mechanical operation under varying system pressures. The valve’s check assemblies feature precision-machined seats made from resilient EPDM elastomer, facilitating a tight, positive seal that minimizes water loss and prevents backflow. These materials are selected to withstand mechanical stress and chemical exposure common in commercial plumbing and fire sprinkler systems.

Regulatory Compliance
This valve complies with stringent industry standards critical for fire protection and potable water safety:
- UL Listing as per UL 1469 for fire service control valves.
- FM Approval confirming performance and durability in fire protection applications.
- Designed in accordance with NFPA 13 standards, ensuring proper integration within fire sprinkler systems.
- Meets ASSE 1015 requirements for backflow prevention assemblies, supporting potable water system integrity.

Operational Compatibility
The Deringer 30G Double Check Valve is rated for a maximum working pressure of 175 PSI (12.1 bar), accommodating typical commercial building water systems and fire protection pressure demands. Connection options include standard flanged and grooved ends for ease of installation within existing piping networks. The valve supports both horizontal and vertical pipe orientations, maintaining consistent performance and compliance regardless of system layout. Operating temperature ranges from 33°F to 140°F (0.5°C to 60°C), suitable for indoor mechanical rooms and subterranean installations where temperature control may vary.

Application Insights
Specifically designed to prevent backflow contamination in non-health hazard scenarios, the Deringer 30G Valve protects potable water supplies from pollutants commonly found in fire protection lines such as dirt, rust, and chemical treatments. Its robust construction ensures longevity in challenging environments including warehouses, manufacturing facilities, and commercial high-rises. The valve’s compatibility with standard fire sprinkler system types – wet, dry, pre-action, and deluge – simplifies system design and maintenance. By selecting this assembly, system designers and maintenance engineers ensure reliable backflow prevention that aligns with municipal and fire code requirements, reducing regulatory risk and costly service interruptions.

Comparison and Maintenance Considerations
Compared to single check valves or reduced pressure zone devices, this Double Check Valve Assembly offers a balance of reliable backflow prevention without the complexity or maintenance overhead of more sensitive devices. Its reversible EPDM seats facilitate straightforward maintenance and part replacement without full valve removal, decreasing downtime during routine inspections. Pre-drilled test cocks support ease of field testing, enabling compliance with required annual backflow tests per NFPA 25 standards. This makes the 30G valve a practical choice for facilities aiming to streamline maintenance protocols while ensuring ongoing code compliance.
