Description
Technical Specifications (Material Focus)
The 4" 3000SSOS&Y FxG Double Detector Check Valve is constructed for robust fire protection applications, featuring a ductile iron body conforming to ASTM A536 standards with a corrosion-resistant fusion-bonded epoxy coating. Internal components include 300-series stainless steel springs and fasteners for reliable corrosion resistance. The check modules incorporate glass-filled thermoplastic material engineered for strength and durability under high-flow conditions. Valve seats utilize replaceable EPDM elastomer discs, providing dependable sealing performance and ease of maintenance. The Outside Stem & Yoke (OS&Y) rising stem design facilitates clear open/close status indication and straightforward manual operation.
Regulatory Compliance
This double detector check valve complies with essential safety and performance standards including:
- UL Listed to UL 312 for detector check valves, ensuring suitability in fire sprinkler systems.
- FM Approved by Factory Mutual for approved fire protection equipment.
- ASSE 1012 backflow prevention certification, confirming effectiveness for non-health hazard applications.
- Meets NFPA 13 and NFPA 25 criteria for installation, testing, and maintenance of fire sprinkler systems, enabling straightforward compliance with local fire codes.
Operational Compatibility
Engineered for fire protection use, this valve supports a maximum working pressure of 300 PSI (20.7 bar), accommodating the demands of high-pressure sprinkler risers. The FxG grooved x flanged end connections comply with ANSI B16.1 (flanged) and AWWA C606 (grooved) standards, allowing flexible integration into existing piping systems. The valve design allows installation in both horizontal and vertical (upward flow) orientations, optimizing versatility. Operating temperature range spans 33°F to 140°F (0.5°C to 60°C), suitable for indoor mechanical rooms and exterior underground vaults alike.
Application and Operational Insights
The 4" 3000SSOS&Y FxG Double Detector Check Valve is ideal for fire protection professionals who require both high reliability and real-time flow detection capabilities. It effectively prevents backflow and cross-contamination during potential sprinkler system activation, while alerting maintenance personnel through its dual pressure differential detection ports. This functionality simplifies diagnostics by signaling flow events without disrupting system operation, aiding prompt leak detection or system testing.
Compared to single check valves, this double detector configuration enhances safety with redundancy—both check valves must fail before backflow can occur, providing an extra safeguard for potable water integrity. Its OS&Y design offers durable valve control with visual position feedback, streamlining inspection routines.
To maximize performance, it is recommended that annual testing of the detection ports is performed following NFPA 25 protocols. The valve’s reversible EPDM seats and modular internals enable efficient onsite repairs without full valve removal, reducing maintenance downtime and costs.
This valve suits fire protection contractors and facility managers tasked with upholding strict fire code compliance while safeguarding municipal water supplies from contamination during fire events or system maintenance.
