An expansion valve, also known as a thermal expansion valve (TXV), is a vital component in an HVAC system. Its primary function is to regulate the flow of refrigerant through the evaporator coil. By controlling the refrigerant flow, expansion valves ensure that the optimal amount of cooling is achieved, enhancing the overall efficiency of the system. | Ashik Hamza
