Taco Mixing Valves

Taco Mixing Valves - Thermostatic and Electronic Mixing Valve Solutions for Stable Water Temperature, Safety, and System Efficiency

Taco mixing valves are designed to provide stable mixed water temperature control in domestic hot water, radiant heating, hydronic heating, and point-of-use applications. These valves help blend hot and cold water to a controlled outlet temperature, supporting safer water delivery, improved system performance, and better comfort in residential, commercial, institutional, and light industrial systems.

The Taco mixing valve product line includes thermostatic mixing valves for potable water and heating applications, high-flow mixing valves for larger system demands, water-heater-mounted mixing valves with recirculation connections, compact point-of-use valves, and electronic iSeries mixing valves for advanced hydronic temperature control.

For domestic hot water applications, Taco lead-free mixing valves with NSF 61, ASSE 1017, and ASSE 1070 certifications help support safe tempered water delivery while allowing water heaters to store water at higher temperatures. This can help increase effective storage capacity and support bacteria control while still delivering mixed water at a safer outlet temperature.

For hydronic heating systems, Taco heating-only and iSeries mixing valves help maintain the proper supply water temperature for radiant floors, injection pumping, outdoor reset control, fixed supply temperature control, and boiler protection. iSeries models add electronic control, zone-to-zone flexibility, and built-in protection against boiler flue gas condensation.
