The 4-way reversing valve operates as the switching device in heat pump systems, reversing the direction of refrigerant flow between the compressor and the evaporator/condenser.

• When the coil is not energized, refrigerant flows in cooling mode, sending discharge gas to the outdoor heat exchanger
• When the coil is energized, the pilot valve shifts the main slide, reversing flow to enable heating mode, directing hot refrigerant to the indoor heat exchanger

This automatic switching mechanism ensures efficient heat transfer, quick temperature response, and stable compressor operation across seasons. It allows a single refrigeration circuit to perform both cooling and heating, significantly improving energy efficiency and reducing equipment complexity.

1. Ensure compatibility with system pressure, refrigerant, and pipe size before installation
