Expansion valves allow for the control of a refrigerant flow through a variable orifice as it passes through your Rheem furnace. When refrigerant pressure is low or the system is holding excess pressure, the expansion valve will restrict flow. As pressure increases, the valve opens allowing more flow. Different capacities and brand compatibility are designed to work with your Rheem furnace.

A Furnace Expansion Valve controls the flow of refrigerant through the condensing unit to the evaporator coil in a heat pump.
