Description

Technical Specifications (Material Focus):
The 20" Deringer Low Head Loss Double Check Valve Assembly features a heavy-duty iron body treated with a corrosion-resistant coating to endure the mechanical and environmental stresses common in fire protection systems. Internal springs and fasteners utilize stainless steel for enhanced rust resistance and longevity. Check modules are fabricated from high-strength thermoplastics to ensure consistent sealing integrity, paired with EPDM elastomer seats that are reversible and replaceable for sustained system reliability over extended service life.

Regulatory Compliance:
This assembly is UL Listed under UL 1469 standards specifically addressing fire service water control valves. It holds FM Approval from Factory Mutual, verifying its operational safety and performance within fire protection infrastructures. Conformance with ASSE 1015 certification and compliance with NFPA standards NFPA 13 (Installation of Sprinkler Systems) and NFPA 25 (Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems) confirm its alignment with national fire safety codes.

Operational Compatibility:
Designed to function at a maximum working pressure of 175 PSI (12.1 bar), the valve assembly supports ANSI B16.1 flanged and AWWA C606 grooved connections, allowing integration into diverse piping systems. It facilitates both horizontal and vertical (upward flow) installations, accommodating a variety of mechanical layouts. The low head loss design reduces pressure drop across the valve, thereby preserving adequate sprinkler head pressure during fire suppression events, which is critical for system efficacy.

Use Cases and Practical Insights:
Ideal for fire protection specialists managing large commercial, industrial, and municipal sprinkler networks, this double check valve assembly provides dual independent barriers against back-siphonage and contaminant intrusion. Its robust construction reduces maintenance demands under harsh conditions, while built-in pre-drilled test cocks enable efficient annual inspections and differential pressure testing. The dual check feature combined with low hydraulic resistance significantly improves system reliability and efficiency compared to single check valves, especially in high-flow scenarios where maintaining water supply integrity is paramount.
