Emerson Climate Technologies XC-726 HC-2B Thermal Expansion Valve

The GE Fanuc Emerson XC-726 HC-2B thermal expansion valve is a thermostatic expansion valve (TXV) designed for industrial refrigeration and HVAC systems to regulate refrigerant flow based on temperature and pressure conditions. Part of the Emerson / Alco Controls family, this direct-mount valve uses a temperature-sensing bulb with mechanical modulation to deliver stable superheat under varying load. It is rated up to approximately 600 psi and operates from -40°C to 150°C, with multi-refrigerant compatibility (application dependent). Common installations include chillers, air conditioning systems, heat pumps, rooftop units, transportation cooling, and other industrial refrigeration or process cooling applications where precise refrigerant control supports efficiency. Maintenance teams and system integrators rely on this valve for refrigeration system optimization, performance tuning, and replacement of worn or faulty expansion valves. Common replacements include Emerson XC-726 MC-2B, Danfoss TE Series Expansion Valve, and Carel Thermostatic Expansion Valve.
