The innovative Caleffi AngleMix 520 series thermostatic mixing valve stood winner under the Plumbing category of AHRI awards.

It accurately controls mixed water temperature in residential and commercial domestic hot water systems. It is the industry’s only thermostatic mixing valve with an angle-styled body. This geometry minimizes the number of elbows required which reduces overall installation cost. Additionally, AngleMix is the industry’s only thermostatic mixing valve that can close off its hot and cold ports at 100% tightness, preventing temperature creep or droop.

Caleffi AngleMix 520 series easily mounts at the tank-type, or tankless type water heater outlet and the angle-style body mixed temperature outlet is in line with the water heater outlet. This facilitates straight-line piping which reduces pipe elbows and overall space required for installation. The AngleMix has a lockable set point adjustment knob and includes a temperature gauge on the mixed temperature outlet for instant verification of temperature.

The precision engineered anti-scale internal components minimize service requirements, assure smooth operation and long life, and compensate for temperature and pressure fluctuations of the incoming hot and cold water. Available in a wide variety of end connections, the angle style body design is compatible with all common pipe types and connection styles from ½” to 1” sizes. AngleMix is certified to ASSE 1017 standard for point of distribution domestic water systems.
