iSeries Mixing Valves
Precise, Cost-Effective Temperature Control for Your Heating Systems
Taco iSeries ® Mixing Valves provide precise and cost-effective temperature control for your heating systems, the flexibility of zone-to-zone control, plus built-in protection against boiler flue gas condensation. Available in 2-way, 3-way or 4-way injection configurations, for either outdoor reset control or fixed water supply temperature applications, and operate off constant power or relay end switch. Features include a ball valve design, High Cv, manual operation button, solid-state microprocessor, multi-status LED indicator light and easy, one-hand actuator removal.

Use the Taco Setpoint iSeries-S Mixing Valves instead of athermostatic mixing valve for precise dial-in supply watertemperature control to a heating system. The directdrive microprocessor-based actuator modulates a 2-way,3-way or 4-way valve to inject different rates of hotwater into the cooler system return water. In combinationwith the optional boiler protection sensor, theiSeries valves provide the unique benefit of optimaltemperature control with boiler protection. The setpointtemperature is adjustable from 80ºF to 180ºF using a dial located on top of the actuator. A 15ºF setback of the supplywater can be initiated for additional unoccupied or nighttime setback control. An external multi-status LED indicatorlight, plug-in wiring connections and an easy to remove actuator makes installation and diagnostics a snap.
