Lennox 78M25 Reversing Valve

The Lennox 78M25 Reversing Valve is an essential component in HVAC systems with heat pumps. This operates by reversing the flow of the refrigerant around the system. In heating mode, the valve turns around to enable the heat pump to draw heat from the ambient air and deliver it inside. This cooling mode, the rate of flow of refrigerant remains the same and as a result, such heat pumps help in extracting heat from inside the building and discharging it outside. It is usually made of high-quality brass material to allow for its long-lasting and corrosion-free features.
