Description
The Heatcraft Refrigeration SBFSE-B-Z Thermal Expansion Valve (TXV) is a precision refrigerant metering device designed for 1-1/4 to 2-ton commercial refrigeration and HVAC systems, featuring 3/8" x 1/2" ODF connections. Installed in the liquid line at the evaporator inlet, it senses evaporator temperature and pressure to regulate refrigerant flow and maintain proper superheat. This controlled flow helps optimize evaporator performance, improve cooling efficiency, and provide stable temperature control. It is commonly used with commercial refrigeration equipment, evaporator coils, condensing units, and air-conditioning systems, supporting reliable operation and helping protect the compressor from liquid refrigerant return.
