Trane VAL18579 Thermal Expansion Valve (TXV)

The Trane VAL18579 Thermal Expansion Valve is used to control the flow of refrigerant into the evaporator by modulating the flow depending on the element, which is often used in cooling units in HVAC systems, to be operated in a controlled manner. It works by detecting the temperature and pressure conditions to keep the superheat at the right level and to provide efficient heat exchange. It is connected to the evaporator inlet and to the refrigerant line and system to control the flow accurately. This cooling efficiency assists in stabilising system, operation and aids in maintaining a consistent temperature.
