The Deringer 30G Double Check Backflow Valve offers a dependable solution tailored for commercial fire protection and plumbing systems. Designed for system designers, maintenance engineers, and facility managers, this valve ensures effective prevention of backflow contamination, safeguarding potable water supplies and enhancing fire sprinkler system reliability.

• Durable Construction: Built with a robust ductile iron body, complemented by brass internal components and stainless steel springs, the valve withstands harsh industrial environments while resisting corrosion.
• Precision-Sealed Check Assemblies: Incorporates carefully machined seats made from high-quality EPDM elastomer, creating a tight seal that minimizes water loss and reliably blocks reverse flow under varying pressure conditions.
• Regulatory Compliance: UL Listed to UL 1469, FM Approved, and compliant with NFPA 13 and ASSE 1015 standards, providing confidence in meeting fire protection codes and potable water safety regulations.
• Operational Versatility: Rated for pressures up to 175 PSI, compatible with both horizontal and vertical pipe orientations, featuring flanged and grooved end connections for straightforward installation across diverse commercial applications.
• Wide Temperature Range: Reliable operation between 33°F and 140°F (0.5°C to 60°C), suitable for indoor mechanical rooms or underground installations subject to temperature fluctuations.
• Application Flexibility: Specially designed for non-health hazard backflow scenarios, supporting wet, dry, pre-action, and deluge sprinkler systems commonly found in warehouses, manufacturing sites, and commercial high-rises.
• Maintenance-Friendly Design: Reversible EPDM seats allow easy inspection and replacement, simplifying routine maintenance and reducing system downtime compared to more complex backflow prevention devices.

By integrating the Deringer 30G Double Check Backflow Valve into fire protection systems, users can effectively protect potable water from contaminants like dirt, rust, and chemical treatments.
