Description

Technical Specifications (Material Focus)

Main Body: Heavy-duty ductile iron (ASTM A536) with fusion-bonded epoxy coating to resist corrosion and mechanical wear, suited for both subterranean and mechanical room installations.
Internal Components: Equipped with 300-series stainless steel springs and fasteners to maintain consistent valve operation under varying pressure conditions.
Check Modules: Two independent check valves constructed from glass-filled Noryl™ or equivalent thermoplastic designed for durability and low friction to minimize pressure loss.
Seats: Precision-engineered EPDM elastomer discs that are reversible and replaceable to ensure positive hydraulic seal and long-term reliability.
Butterfly Valve: Integrated high-performance butterfly valve with resilient seat ensures quick shutoff and facilitates routine inspections and system isolation without disrupting system pressure.

Regulatory Compliance

UL Listed to UL 312 standards specifically for detector check valves used in fire protection water systems.
FM Approved and tested under Factory Mutual guidelines for fire protection system reliability.
Meets ASSE 1012 standards for detector check valves to prevent the backflow of contaminated water into the potable supply.
Complies with NFPA 13 for installation requirements and NFPA 25 for inspection and testing of backflow assemblies in fire sprinkler systems.

Operational Compatibility

Working Pressure: Rated for up to 175 PSI (12.1 bar), providing suitability for most commercial and industrial fire protection water supplies.
Temperature Range: Operates efficiently within 33°F to 140°F (0.5°C to 60°C), accommodating typical fire system water environments.
Connection Type: Available in 2" flanged ends conforming to ANSI B16.1, compatible with standard fire protection piping infrastructures for ease of integration and maintenance.
Installation Orientation: Designed for horizontal installation ensuring consistent hydraulic performance and correct detector activation under system flow conditions.

This 2" Double Detector Check Valve with Butterfly Valve is engineered to deliver reliable backflow prevention critical in fire protection systems where cross-contamination risk is high. Its dual check valve configuration continuously monitors water flow, activating a water flow alarm upon system use, providing early warning in fire events. The integrated butterfly valve enhances operational control by enabling isolation and pressure management during inspections or maintenance without interrupting the overall water supply.

Ideal for commercial buildings, multi-residential complexes, and industrial fire protection setups, this assembly protects the potable water supply by preventing backflow of stagnant or potentially contaminated water from fire lines. By meeting relevant UL, FM, ASSE, and NFPA codes, this valve supports compliance with stringent fire safety regulations, reducing liability risks and facilitating system approvals from authorities having jurisdiction.

Compared to single check valves or assemblies lacking integrated flow detection, this unit offers enhanced system monitoring capabilities and simplifies maintenance workflows. The corrosion-resistant materials and reversible elastomer seats reduce downtime and replacement costs over its service life. For fire protection professionals seeking a dependable detector check valve assembly with integral flow control, this product balances durability, compliance, and operational functionality effectively.
