Description
The Heatcraft Refrigeration SBFSEAZ 1/2 – 1-Ton Thermal Expansion Valve (TXV) 3/8″ x 1/2″ ODF Sweat is a refrigerant control component that regulates the flow of liquid refrigerant into the evaporator based on temperature and pressure changes. It operates by sensing superheat conditions and adjusting refrigerant feed to maintain stable evaporation and prevent coil flooding or starvation. In HVAC systems, it is used in split air conditioning and refrigeration units to ensure efficient heat exchange and consistent cooling performance. It is typically connected at the evaporator inlet during service fitting and supports improved energy efficiency, system protection, and reliable temperature.
