Caleffi ThermoProtec™ Thermostatic Mixing Valve, High-Flow Anticondensing, Series: 280, 1-1/4 in Nominal, NPT, 150 psi, 40 to 212 deg F, Media: Water/Glycol, Brass Body, Stainless Steel Trim, EPDM Seal, 7-5/8 in L x 6-13/16 in H

The ThermoProtec™ boiler protection high-flow thermostatic mixing valve is used in hydronic heating systems with non-condensing boilers, including solid fuel, biomass, gas, LP or oil-fired. It can be installed with steel, cast iron and copper tube style boilers, automatically controlling the return water temperature, preventing condensation of the water vapor contained in the flue gas. The 280 series ThermoProtec™ valve mixes by-pass flow from the boiler with return flow from the system, sending a fixed temperature flow to the boiler which protects against corrosion from condensation occurring when a minimum flue gas temperature is not otherwise maintained.
