Xylem-Bell & Gossett 110199LF Dual Valve 8 Pressure Reducing and Relief Valve,1/2 Inch ,12 Psi 30PSI

The Xylem-Bell & Gossett 110199LF is a dual valve that combines the functions of a pressure lowering valve and a pressure relief valve into one compact device. It's composed of lead-free brass, which is durable and corrosion-resistant. This valve is utilized in hydronic heating systems, particularly hot water boilers. Its principal role is to keep the water pressure safe and consistent throughout the boiler system. The pressure lowering valve reduces the incoming water pressure to a predetermined amount (often 12 psi in this type), safeguarding the boiler from any damage caused by excessive pressure surges. The relief 1valve functions as a safety feature, 1automatically releasing excess pressure if it exceeds a certain level (usually 30 psi on this type), avoiding boiler ruptures.
