Caleffi 520619A AngleMix 3-Way Thermostatic Mixing Valve 1" Sweat Union with Temperature Gauge

The Caleffi 520619A is an AngleMix 3-way thermostatic mixing valve with 1" sweat union connections and temperature gauge. It mixes supply and return water to deliver a controlled outlet temperature to the heating circuit.

AngleMix valves are 3-way thermostatic mixing valves for hydronic heating systems. They blend hot supply water with cooler return water to hold a steady, adjustable supply temperature for low-temperature circuits such as radiant floor heating. The angle body pattern simplifies piping on near-boiler and manifold installations.

Before ordering, confirm your piping is 1" and suited to sweat connections. This valve is for hydronic heating, not for potable hot water tempering.
