Description
Trane VAL11877 Thermal Expansion Valve is a refrigerant control component that controls the flow of refrigerant into the evaporator in heating and cooling systems. It works on the concept of detecting temperature and pressure variations to regulate refrigerant flow to ensure that superheat is maintained in order to ensure effective heat exchange. It is typically part of HVAC systems, like air conditioning or heat pump units in residential or light commercial systems, and is connected at the evaporator inlet to allow a controlled supply of refrigerant. Its operation facilitates balanced cooling operation, enhances system efficiency and assists in keeping the operating conditions constant.
