Product Overview

The Danfoss TX2 (Part No. 068Z3206) is a high-performance thermostatic expansion valve from Danfoss' TX series, engineered for precise refrigerant flow control in residential and light commercial HVAC, air conditioning and refrigeration systems.
 
As the critical throttling device in the refrigeration cycle, it monitors the temperature of the refrigerant leaving the evaporator via a stainless steel thermal bulb, adjusting the valve opening to match real-time cooling demand. This ensures optimal refrigerant flow, maximizes evaporator efficiency, and protects the compressor from liquid floodback and overheating.
