Description

Technical Specifications (Material Focus)
The 12" Double Check Valve with OS&Y and Low Flow Features is engineered for reliable backflow prevention in fire protection and potable water systems. The main body is constructed from fusion-bonded epoxy-coated ductile iron conforming to ASTM A536, ensuring high corrosion resistance and durability in demanding environments. Internal components, including springs and fasteners, are fabricated from 300-series stainless steel to resist corrosion and maintain performance under continuous service conditions. The check modules utilize glass-filled Noryl™ or equivalent high-strength thermoplastic, providing wear resistance and structural integrity. Seats are composed of reversible and replaceable EPDM elastomer discs, guaranteeing a consistent seal and facilitating maintenance without the need for full unit replacement.

Regulatory Compliance
This double check valve assembly complies with critical regulatory and industry standards to meet safety and performance benchmarks:

UL Listed: Certified under UL 1469 for fire service water control valves
FM Approved: Endorsed by Factory Mutual for fire protection applications
ASSE 1015: Conforms to American Society of Sanitary Engineering standards governing backflow preventers
AWWA C510: Adheres to American Water Works Association standards for valve design and testing
NFPA Compatibility: Supports compliance with NFPA 13 and NFPA 25 standards for sprinkler systems installation, inspection, and maintenance

Operational Compatibility
The valve is designed for versatility in fire protection system integration:

Working Pressure: Rated for up to 175 PSI (12.1 bar), suitable for most commercial and industrial fire systems
Temperature Range: Operates efficiently between 33°F to 140°F (0.5°C to 60°C)
Connections: Equipped with Outside Screw and Yoke (OS&Y) style gate valves for ease of isolation and maintenance, compatible with standard 12" flange or grooved end piping
Flow Features: Incorporates low flow capabilities allowing precise operation in low-demand scenarios without compromising backflow prevention
Installation: Suitable for both horizontal and vertical upward-flow orientations, ensuring flexible placement within complex piping arrangements

This 12" Double Check Valve with OS&Y and Low Flow Features addresses critical concerns faced by fire protection engineers, facility managers, and industrial plumbers who require a dependable solution to prevent potable water contamination while accommodating varying flow rates. Its OS&Y design significantly reduces maintenance downtime by enabling isolated servicing of the valve without system disruption. The inclusion of low flow capabilities enhances system responsiveness during periods of minimal demand, a feature often absent in standard backflow preventers and critical for maintaining system readiness and compliance in fire sprinkler systems.

Compared to conventional double check valve assemblies, this product’s emphasis on low flow sensitivity and OS&Y gate valves offers tangible operational advantages, particularly in environments where maintenance access is limited, or water usage fluctuates extensively. For end-users, this translates to extended valve lifespan, reduced operational costs, and adherence to stringent safety codes. Integration of pre-drilled test cocks facilitates annual backflow testing and differential pressure monitoring, aligning with jurisdictional fire codes and NFPA 25 guidelines.

In summary, this 12" Double Check Valve is tailored for high-demand fire protection systems requiring robust backflow prevention with flexible flow handling and straightforward maintenance. It is particularly suited for commercial buildings, industrial facilities, and municipal water systems where system integrity and regulatory compliance are paramount.
