Valves • Thermostatic Valves

Thermostatic mixing valves blend hot and cold water to ensure constant outlet temperatures, which prevents scalding. Typically self-acting and featuring two-port or three-port design, thermostatic valves are used within a variety of industrial equipment including compressors, oil coolers, tank heaters, pumped recirculating hot water systems, emergency eyewashes, drench showers, and combination units. Thermostatic valve types include point of use valves, standard valves, high/low valves, high/low recirculation station, and emergency mixing valves.
