Honeywell am102-ut-1lf/u 1 Inch Npt Union Mixing Valve Lead Free

Product Description

The Honeywell AM102-UT-1LF/U is a 1 inch NPT union mixing valve designed for residential, commercial, and industrial hot water systems. This valve is part of the AM-1 series, built to adjust, maintain, and limit hot water temperature at the point of use. It provides consistent mixed outlet water temperature even when operating conditions change, making it a reliable choice for domestic hot water, radiant floor heating, solar hot water systems, combo systems, and space heating applications. The AM102-UT-1LF/U is also well suited for nursing homes, public facilities, automatic faucets, greenhouses, photo processing, and industrial applications where precise temperature control is critical. The valve offers anti-scald and anti-chill protection by reducing flow within seconds if the cold water supply is interrupted. This fast response time helps protect building occupants and equipment from sudden temperature spikes. The body is constructed from Teflon-coated, nickel-plated low lead brass, which resists mineral buildup and extends the service life of the valve. EPDM O-ring packing provides a reliable seal and stands up to repeated thermal cycling. The dual-purpose design allows the valve to function as either a mixing or diverting valve, giving installers added flexibility. It operates at a minimum flow rate of 0.5 gallons per minute and features a proportional valve mechanism for simultaneous control of hot and cold water inputs. The Cv rating of 3.9 supports efficient flow across a wide range of system pressures up to 150 psi. The lead-free construction meets low lead content requirements of less than 0.25 percent by weighted average, with the LF suffix in the part number confirming compliance. This valve is CSA certified and approved to NSF/ANSI, IAPMO, and ASSE 1017 standards, making it code-compliant in most jurisdictions across North America. Installation and maintenance are straightforward thanks to the union NPT connection type and the easy-access design of the valve internals.
