Hoffman Specialty, a unit of ITT Industries (Xylem), offers a wide range of products for steam and hydronic systems. From steam traps to valves, from boiler feed units to temperature regulators and vacuum breakers, whether residential or commercial, Hoffman Specialty can fill the requirement. Hoffman Specialty was founded in 1913 by George D. Hoffman with the introduction of the Hoffman No. 1 Automatic Siphon Air Vent Valve for steam radiators, and was acquired by ITT Industries in 1970.
