Lennox 72L28 Reversing Valve

The Lennox 72L28 Reversing Valve built for and compatible solely with Lennox HVAC systems. It is used in mainly heat pumps that are a combination of both heating as well as cooling systems. The valve controls the flow of refrigerant in the system while supplying it throughout the system. In the heating mode, the valve controls the flow of refrigerant to draw heat from the outside environment and take it inside. In cooling mode, the cycle is reversed where heat is drawn from within the home and expelled outside. The robust aluminum works on a normal 24V electrical supply. It is also suitable for 50/60 Hz electrical systems.
