1-1/2" Brass Swing Check Valve, Lead-Free, Copper x Copper

1-1/2" Lead-Free Brass Swing Check Valve – Backflow Protection You Can Count On

The 1-1/2" Brass Swing Check Valve is engineered for dependable backflow prevention in commercial, industrial, and residential systems. It’s built to provide automatic protection against reverse flow in water and hydronic piping applications, helping maintain system integrity and water safety standards.

Manufactured from lead-free brass and rated for high temperatures and pressures, this valve is ideal for potable water lines, hot water systems, and mechanical installations. It features a swing-type disc that opens with forward flow and closes when flow reverses, effectively sealing against backflow with minimal flow restriction.
