  • A respected national supplier of radiator valves and regulating sensors for the heating and cooling industry since 1975, Macon Controls – a division of the Tunstall Corporation – maintains a solid reputation for energy-efficient products, trouble-free service, and virtually non-existent failure rates. Distinguished by superior quality and performance, all Macon valves and controls conform to ASHRAE Standard 102P-1983 and European Standard EN 215/1215.

    Macon Controls are ideal for hydronic and low-pressure steam heating applications – and they deliver up to 30 percent energy savings. A complete line of valve sizes and non-electric control models is available, allowing for temperature regulation of radiators, convectors, fin-tube baseboard, fan coils or wherever individual control is required

    As a pioneer and developer of “smart solutions”, Macon also offers high quality, innovative accessories, including Umbrella adapters to upgrade existing thermostatic controls to Macon operators and E-Z Fit Conversion kits which transform manual radiator valves to temperature sensitive self-acting valves.
