The Ranco® 4-Way Reversing Valves are designed for heat pump applications such as window-type, unitary and split systems. They are the key component to provide heating and cooling from the heat pump system by reversing the flow direction of the refrigerant. These solenoid operated valves are slide type with a 4-way pilot valve, and operate under the full pressure of the heat pump system.
