Bristol 6″ Flanged OS & Y Gate Valve 300 PSI

The Bristol 6″ Flanged OS & Y Gate Valve 300 PSI is engineered to maintain safety integrity and ensure dependable fluid isolation across fire protection mains, commercial high-rise sprinkler risers, industrial fire loops, and municipal water supply infrastructure. Built with a robust ductile iron body and resilient seated wedge, this 6-inch flanged valve delivers bubble-tight shutoff against working pressures up to 300 PSI. The Outside Screw and Yoke construction keeps the operating stem threads external to the fluid waterway, protecting critical drive components from corrosion, debris accumulation, and mechanical wear. Designed with standardized ANSI flanged connections and pre-drilled boss tapping for supervisory tamper switch mounting, it offers seamless integration into monitored fire protection control assemblies.
