Description
The Marvair 20337 Thermal Expansion Valve Assembly is used to control the flow of refrigerant to the evaporator in HVAC systems. It is mounted in the refrigeration R410A circuit and turns on and off the refrigerant depending upon load and temperature conditions to provide efficient heat absorption, and prevent evaporator flooding. It has a 208/230 voltage and operates together with compressors, condensers, and other components to ensure the pressure and the temperature remain constant. It allows to ensure proper operation, steady cooling and general system efficiency.
