Lennox 26K49 TXV 320074-702 Using a lower VA rating

Using a lower VA rating can lead to overheating and failed ignition sequences

the 100110704 ensures consistent BTU output while minimizing NOx emissions

By regulating the R410A refrigerant flow into the evaporator

Wide Operating Range: Rated for static pressures up to 400 psig

Space Optimization: Combining the sensor and relay in one housing reduces the number of components inside the panel

Lennox 26K49 TXV 320074-702 Using a lower VA ratingThe Lennox 26K49 Thermostatic Expansion Valve (TXV) is a critical metering component engineered specifically for 3 ton R22 refrigerant systems utilizing a B10 flowrater configuration. Designed to optimize evaporator efficiency, this internally equalized expansion valve maintains precise superheat levels across varying thermal loads, preventing liquid slugging and protecting the compressor from premature failure.
