Description

Technical Specifications (Material Focus)

Main Body: Constructed from fusion-bonded epoxy-coated ductile iron (ASTM A536) to resist corrosion and mechanical wear in fire protection environments.
Internal Components: Incorporates 300-series stainless steel springs and fasteners, providing long-term resistance to rust and mechanical fatigue under frequent cycling.
Check Modules: Equipped with dual stainless steel check valves delivering redundant backflow prevention within a compact 4" assembly size.
Valve Type: Features a Full-Port Exterior OS&Y (Outside Stem and Yoke) gate valve for straightforward monitoring of valve position and convenient maintenance access.

Regulatory Compliance

UL Listing: Certified to UL 1469 for double check valve backflow prevention assemblies, verifying adherence to fire system safety standards.
FM Approval: Recognized by Factory Mutual for dependable performance in fire protection water supply systems, ensuring reliability under emergency conditions.
ASSE 1015: Compliant with American Society of Sanitary Engineering standards for reduced hazard backflow prevention devices.
System Compliance: Designed to support NFPA 13 and NFPA 25 compliance, incorporating pre-drilled test cocks enabling differential pressure testing and annual inspection protocols.

Operational Compatibility

Pressure Rating: Rated for maximum working pressure of 175 PSI (12.1 bar), suitable for typical municipal and private fire protection water supplies.
Temperature Range: Operates effectively between 33°F and 140°F (0.5°C to 60°C), accommodating a broad range of environmental conditions.
Connections: End connections configured with flanged or grooved options conforming to ANSI B16.1 and AWWA C606 standards, compatible with existing fire system piping.
Installation Orientation: Supports both horizontal and vertical (upward flow) installation layouts, providing flexibility in system design and retrofit scenarios.

This 4" Double Check Assembly With FxG OS&Y is purpose-built to prevent backflow contamination in residential and commercial fire protection systems. The dual check valves provide dual redundancy, ensuring potable water remains unpolluted from potential cross-connections—a crucial safeguard for municipal water authorities and property owners.

Its OS&Y gate valve design facilitates clear operational status indication and simplifies routine maintenance without system shutdown, minimizing downtime. The epoxy coating and stainless steel internals extend service life even in demanding subterranean vaults or mechanical rooms where environmental stresses are prevalent.

By integrating this assembly, fire protection system operators ensure compliance with critical safety standards, pass inspection with pre-installed test cocks allowing for accurate differential pressure verification, and reduce the risk of costly water supply contamination events.

Compared to single check devices or assemblies lacking an OS&Y valve, this unit stands out by combining robust construction and practical maintenance features tailored for fire protection professionals who require durable, code-compliant backflow prevention solutions optimized for high flow and pressure environments.
