Bronze Swing Check Valve | ½-Inch to 2-Inch Options

The Bronze Swing Check Valve by Fire Protection Products Inc is engineered for reliable, unidirectional flow control in commercial fire protection assemblies, water supply networks, and plumbing layouts. Designed to prevent backflow and maintain system integrity, this valve installs primarily within wet and dry fire sprinkler systems, auxiliary piping lines, and supply configurations where maintaining positive shut-off and debris clearance is critical. When forward pressure drops, the internal floating clapper assembly automatically swings closed to prevent reverse flow, ensuring consistent water delivery across the network.

This component complies with strict life safety mandates under NFPA 13 (Standard for the Installation of Sprinkler Systems) and NFPA 25 (Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems). It satisfies mandatory backflow prevention and operational reliability requirements for commercial contractor installations, undergoing rigorous hydrostatic testing to verify seat tightness and structural integrity under active operating pressures.

Key Features & Construction

• Durable Bronze Body: Heavy-duty bronze cast construction provides superior corrosion resistance and longevity in demanding mechanical and fire protection environments.
• Floating Clapper Design: Full-floating clapper assembly ensures positive sealing and facilitates smooth debris clearance during high-flow events.
• Resilient NBR Seal: Integrated NBR (Nitrile) seat seal delivers a leak-tight positive seal against back pressure.
• Versatile Sizing Options: Available in six distinct configurations ranging from ½-inch to 2-inch threaded connections to match precise piping layouts.

Technical Specifications & Compliance Table

Contractors must verify local Authority Having Jurisdiction (AHJ) requirements, system pressure ratings, and pipe sizing prior to installation. Ensure proper flow orientation according to the body markings.
