THERMOSTATIC MIXING VALVES
Application
Legend thermostatic mixing valves are designed for applications requiring temperature control, scald
prevention and reduction of thermal shock in domestic potable water distribution (Model T-45NL)
and radiant heating installations (Model T-46NL). The three-way thermostatic mixing design permits
controlled water temperatures to individual or multiple fixtures, gang showers or hydronic heating loops.
