An expansion valve is a precision metering device that regulates the flow of refrigerant into the evaporator in cooling and heat pump systems. It ensures optimal pressure and temperature for efficient heat exchange. In heating equipment that incorporates refrigeration cycles, a properly functioning expansion valve is critical for performance. When servicing such systems, replacing a worn or clogged expansion valve can restore efficiency and prevent compressor damage.
