Taco 5122-C2 Thermostatic Mixing Valve

The Taco 5122-C2 is a thermostatic mixing valve built from forged brass for precise temperature control. It serves residential and light commercial plumbing systems that require blended water delivery between 85 and 120 degrees Fahrenheit.

Verify pipe size and inlet temperatures before

Confirm the supply lines use 1/2 inch union sweat connections to match the valve inlets and outlets. Ensure the hot supply runs between 120 and 180 degrees Fahrenheit and the cold supply stays between 39 and 80 degrees Fahrenheit for proper operation.

Replaces older non-thermostatic mixing valves

This valve upgrades installations that lack automatic temperature regulation or certified scald protection. The jump is worth it when ASSE 1017, ASSE 1070 and NSF 61 compliance are required by code or project specification.

Questions about this item

Does the 5122-C2 mixing valve ship with the union sweat fittings or must they be purchased separately?

The valve includes integral union sweat connections for both 1/2 in hot and cold inlets and the 1/2 in outlet, so no separate fittings are required for a standard copper installation.

How do I decide whether the 1 to 14 gpm flow range suits my application?

Choose this valve when your design flow falls between 1 and 14 gpm; the thermostatic element maintains the set point across that entire range while meeting ASSE 1017 and ASSE 1070 performance requirements.

What outlet temperature will the valve deliver when the hot inlet is at 180 Degrees F and the cold inlet at 39 Degrees F?

The adjustable thermostatic cartridge can be set anywhere from 85 to 120 Degrees F and will hold that temperature even with 180 Degrees F hot and 39 Degrees F cold supply conditions.
