Description
The Lennox 11X74 Expansion Valve operator is a metering part, an essential component used to regulate the flow of liquid refrigerant into the evaporator coil. By responding to changes in pressure and temperature at the evaporator outlet, this component modulates the volume to maintain a consistent superheat. In residential and commercial split-system air conditioners or heat pumps, it is typically installed at the inlet of the indoor cooling coil. Within the refrigeration cycle, the valve facilitates the pressure drop necessary in an HVAC system.
